1980
Directed by Sean S. Cunningham
Written by Victor Miller and Ron Kurz
Friday the 13th is a bit imposing to discuss. It's simultaneously very difficult to write about (its reputation precedes it, and as a subject of film criticism it's been as fully excavated as any of history's most celebrated and foundational classics, to the point that, like it or lump it, we kind of have to agree that it is one) and very easy (its reputation precedes it and there's a certain ritual pleasure to Friday the 13th, and hence a ritual pleasure in simply reciting in one's own voice what everyone already knows about its plain scenario, its doofy characters, its grindhouse-adjacent production quality, and the winning twist it puts at the end, such that it seems like it ought to have precluded this movie ever turning into the 1980s' most-franchised slasher brand, and yet with seven sequels in that decade—notwithstanding the several more still to come—that's what happened anyway).
I'm going to try to say new things about Friday the 13th, though I expect that's impossible. But, to begin with, I was not prepared to much enjoy my return to the headwaters of Crystal Lake; shotgunning the whole rest of the 80s Fridays a couple of years ago, but without rewatching the original, which till then had been the only one I'd seen—an original which is somehow exactly the same as all its sequels and entirely unique within its series—might have played some role in this. However, what probably helped the most was my recollection of it as pretty lackluster, a mediocre slasher film that also tended to have bad photography, altogether amounting to a rather dull murder spree despite its enjoyably unusual killer. Basing this opinion on that single watch, I don't know what the chip on my shoulder was that night ten years ago, but that chip has detached itself in the decade since: prepared to be bored, I wasn't; prepared to find its characters mildly annoying and incredibly poorly-acted, they weren't (too badly, anyhow); prepared to grumble about too many unlit night scenes, even that turned out to only be, like, six shots out of a 95 minute film, and clearly the combination of a format upgrade for Friday the 13th itself and the march of cinematographic trends here in 2024 has been of enormous benefit to DP Barry Abrams in 1980. His creaky old movie with a lighting budget of $20 could generate some spontaneous applause today with its ideas about how darkness, or even daylight exteriors, ought to be rendered in a horror movie, purely on the basis of "wow, this is what cheap, churned-out movies could look like back then?," and while I don't like the flatness of many of the interiors, I could probably go further and note that it's even resisting some of the more disagreeable cinematographic trends of its day, with very little blow-out in its exteriors, and a solid grasp on how to take a sunny summer idyll and make it gloomier only as the horror draws nearer. And so, by modestly praising the photography of a famously sloppily-photographed film, maybe I already have said something new about Friday the 13th.
But its charm is not its craft, as such, even if it doesn't quite get the measure of credit it deserves for it; it's the simplicity, lifted out of complete featurelessness only by the slight convolutions of a "boo" horror flick stinger and, before that, by its aforementioned twist. And that twist—honestly—might not even qualify as "a twist," given that virtually nothing has been done to set it up, and to the extent it is any "twist," it's more exploiting the in-universe assumptions of its heroine than it's ever exploiting its audience's. In any case, I really can't imagine watching Friday the 13th—even watching it completely cold—and not realizing who the killer is within about fifteen seconds of her finally showing her face. (If I could, then it's only because a kid today might have a harder time than their primitive forebear in 1980: for it's possible that the pop cultural weight of the many films subsequent to this would suggest that the first Friday the 13th is likewise about the killer, Jason Voorhees; but, of course, it's not. Its principal writer, Victor Miller, reportedly doesn't even like what the subsequent twelve films did with the innocent exigence for his killer's rampage.) But that's all speculative: Friday the 13th is, needless to say, one of those movies where all its present-day viewers will have been entirely spoiled as to how it ends. I mean, sure, one of the characters in the film is kind of set up as a red herring, in that his whereabouts aren't accounted for during the early murders (he's the last twenty-something teen to die, in fact), and he has a tendency to wander off beforehand, and he's shown some talent with a bladed instrument; but I had to have this actively pointed out to me, because whether that was something consciously built into Miller's script as a misdirect, I don't know if director Sean S. Cunningham noticed, since the actual Friday the 13th has zero interest in drawing your attention to it.
So: simplicity, then. The idea seems to have germinated with Cunningham, who famously started advertising his movie before it even started production, receiving its (frankly) terrible original logo and title card design from a marketing firm who appear to have trained themselves on industrial protocol manuals. He was probably then best-known as a producer on Wes Craven's brutal 1972 thriller, The Last House On the Left—if not that, then for directing not one but two (unrelated!) Bad News Bears knock-offs—but Last House is probably the touchstone, as Cunningham wanted a horror film that backed off on the nihilism, and come the end of the decade he finally got around to it, openly admitting that he was prompted above all by the previous year's Halloween and, more to the point, Halloween's epochal financial success—hence his renaming of the film from the more descriptive A Long Night At Camp Blood, and a brief conversation to establish "golly, boy, but it sure is Friday the 13th, here in the present year," which, as a bonus, confirmed the silly tradition of slasher films being named after calendar events, even if it stands slightly to the side of it. Let us observe that Cunningham obviously wasn't the only one working along similar lines in 1980; yet he made the definitive Halloween knock-off, so that every slasher to come was just as likely to be a knock-off of his as John Carpenter's.
What it undeniably offers, though, is one of horror's most iconic settings. So let's head on out to our cabin in the woods alongside scenic Crystal Lake, our present company being poor Annie (Robbi Morgan), now hitchhiking her way to rural New Jersey (tangibly playing itself) to take her employment as the cook for Crystal Lake's revived kids' summer camp. We've already become familiar with Crystal Lake by way of the 1958-set prologue, where two horny counselors were murdered by an unseen assailant; but that isn't even the only reason that locals such as the truck driver (Rex Everhart) or the crazy prophet of doom (Walt Gorney) call it "Camp Blood." Besides the 1958 murders, there was also the 1957 death by drowning of a little boy, some kid named Jason, and ever since there's been the less lethal but scarcely less threatening legacy of poisonings and arsons that pop up every time somebody makes a damnfool attempt to reopen the place.
Such is the ambition of its new director, Steve Christy (Peter Bouwer), Annie's boss, and he'll not really live to regret it, nor will Annie, this being not-unintelligently foreshadowed, without anyone calling explicit attention to it, when her current ride drops her off at a crossroads adjoining the gates of a cemetery. And so there we have it: what Cunningham and Miller, or uncredited script doctor Ron Kurz, or Abrams, or somebody, is already doing is conjuring the mood that will attend the franchise for several more films, and which is the Fridays' greatest strength, namely their ability to draw their tale out of what presents itself, and has the sensation of, a bunch of local yokel folklore, the kind of scary story you tell out by a campfire, or in a dimly-lit cabin during a violent thunderstorm in between bouts of strip Monopoly. What happens in Friday the 13th happens because it has to, in a sense, because that's how the legend goes ("and it was his mother")—otherwise why would you bother telling the tale? That's fundamentally the case for any horror movie—any movie!—and Halloween obviously prefigures its efforts; but Friday the 13th is already making it a part of the textual fabric of its own atmosphere in ways that very few other horror movies manage.
Inevitably, Annie is the first to die, picked up by another driver in a Jeep whom we conspicuously don't see. (And if I make it sound like I prefer this to Halloween, I'm afraid I do, one minor reason being that I have less of a discombobulating reaction to Friday the 13th's killer driving around the hills in a utility vehicle than I do when Carpenter's far more effortfully-mythic Shape drives around suburbia in his station wagon. I also prefer this film's rumored mysteries of Camp Blood to Michael Myers's established facts.) Annie's absence, anyway, is a source of conversation and annoyance from her colleagues, Steve's other employees, numbering six: Ned (Mark Nelson), the mold for the socially-anxious prank-lover who would become, for better and worse, a fixture of the genre, but at least this one's not shrill and dies first; Jack (Kevin Bacon), the pleasant hunk (though only Bacon's distinctive voice so much as suggests "movie star" in his future); Marcie (Jeanine Taylor), Jack's girlfriend and the straightforwardly horny one; Brenda (Laurie Bartram), the more circuitously and self-amusedly horny one; Bill (Bingspawn Harry Crosby), also a hunk, also horny; and Alice (Adrienne King), an outdoorsy young woman and aspiring artist with a certain thoughtfulness to her, and who is perhaps less horny in comparison to her friends, though there's no particular reason to suspect she doesn't fuck all the time just because she got better dice rolls during strip Monopoly. However, she does wear pants, when she nails pieces of wood together, and she has a short haircut, and she's played by an actress who somewhat physically resembles Jamie Lee Curtis and was blatantly told "act like Jamie Lee Curtis did, in Halloween," so now I guess we can just stop watching these slasher movies I obviously don't like, and jump, immediately, to writing my master's thesis on slasher cinema.
At some length, a storm kicks up, and the camp employees begin to die, one by one, always when separated, till at last we get our Final Girl (thereby confirming that archetype, too), Alice, who stumbles through the killer's tableau of death, arranged for her benefit and ours by our murderer, Mrs. Voorhees (Betsy Palmer). Palmer, as an actor, is up to the most interesting performance in the movie, despite its brief screentime, pitching Voorhees toying with her unwitting victim (Alice naturally assumes she's a bystander who'll render aid), and almost laughing in Alice's face at her obliviousness, as something perilously close to a fourth-wall breaking aside, but not immediately sliding fully into camp. (Not that we shouldn't slide towards camp, but it's Voorhees speaking in her drowned son's voice—"kill her, mommy, kill her!"—that's gonna get us all the way there, basically already an unstressed meta-joke about oepidal serial killers.) Now, Palmer is really not up, physically, to believably keeping herself from being readily outrun or slammed around by a woman less than half her age, but that's okay. She's still the vehicle for one of the low-key weirdest images in horror, that of a cable-knit sweater hung off a deranged old mother, murderously protective of the sanctity of her son's gravesite, and that's surely sufficient.
So I've alluded to how Friday the 13th goes about being a horror movie—sort of less than insistently, and it occupies some nebulous space at the crossroads between the aligned forms of threadbare scary movie, watchably-shitty 80s teen comedy, and 70s porno. Traditionally I've viewed this as its weakness, and I've come around to more-or-less holding it a strength: we have, to begin with, a cast that isn't even really that differentiated by their stereotypes, and who are allowed to bumble around to an almost reckless degree through a number of scenes devoted more to young adult naturalism than even nominal paranoia or comedy. (Their dialogue is by-and-large comprised of affably bantery lines that sort of have the shape of jokes but, even if you allow yourself to get on the movie's wavelength, they're probably never going to do more than elicit a confused smile; this would be one more thing Friday the 13th confirmed for its genre, mostly for the worse this time.) The shadow of Annie's demise is almost even dispelled, for a time. But there is allowed to creep in, not anything like all at once, a sense of immense morbidity: Marcie's apropos-of-very-little relation of a recurring nightmare about blood rains, or, above all, that sequence with a snake that very literally brings the kids face-to-face with violence and death—at the wholly unnecessary cost of a real snake's life, which does, in fact, piss me off—but with attention paid to the genuine disquiet on Crosby's face, which would take him out of the running for "red herring" even if the film's complete disinterest in that hadn't. Even once the murders begin in earnest, we still don't quite have "a horror movie," and I suppose that's a double-edged sword: the movie simply kind of continues but with fewer characters, and it's hard to work up a proper febrile terror when nobody onscreen is scared for more than a couple of seconds right before they eat it. Yet, like I said, the movie continues as if it's ignoring all of Alice's friends disappearing one by one, almost until she's been left all alone before death, and it really can't be ignored any longer. As it's my penchant to get grandiose about slashers, it's worthwhile to ask if it's not a fairly accurate, if violently accelerated, take on this thing we call "life."
I'm not going to go too far and insist that you shouldn't find this boring, but this time, I didn't find Friday the 13th's 95 minutes too much to get at this mood. (Besides, if we're talking cuts, those should all belong to the Final Girl sequence: at some point we do have to wonder if it's worthwhile to have Alice hysterically beat the shit out of Voorhees fully three times before she finally arrives at the deadly solution.) But one guy keeping it less boring than it could be is gore maestro Tom Savini, whose extreme special makeup effects represent another genre-codifying element here, maybe the most important one. Friday the 13th is the film that confirmed the expectation that slasher movies would be about loving depictions of ruptured anatomy; and the quality and amount here, and the insistence on not leaving it to the imagination, is exactly how the slasher film ought to examine the reality of death, and with its climactic awesome machete decapitation, I suppose even the potential price of life. (On the other hand, once it has, at last, become "a horror movie" for its last batch of characters, death tends to happen a lot more offscreen; I suspect this is more a budget thing, or just set-up for the corpse tableau, than "an artistic choice." Either way, we do see the results of death.)
I mentioned up top that Cunningham's direction is underrated; it's not tight, but gets tighter, and is certainly good at parceling out information. (Alice and Bill freaking out while attempting to phone for help from the still-nebulous threat while the camera cranes to follow the wire to its dangling conclusion is not world-shaking good direction, but it is good direction, and he generally knows how to frame and block his actors and use negative space.) But the other big factor, which as much as Savini, few detractors have been able to stand against, is composer Harry Manfredini, whose score is, analyzed in bulk, mostly an energetic ransacking of Psycho and Jaws, though it's creatively derivative thriller music even at its worst; of course, at its best and most iconic, it's innovative indeed, with Manfredini's own voice spitting "kill, mommy" and then manipulated and roughly synthesized until it's not words anymore but more like a malign spirit panting over your shoulder. And nonetheless focusing on that, or even the other thriller cues, discounts how much Manfredini's accomplishing: there's a Pino Donaggio-like elegy fittingly-built for the epilogue which, oddly, Savini devised, and that turned out to be the perfect way to end this half-real, half-legend tale, demanding a surprising amount of patience as we enter into a largely new and metaphorical territory with Alice out there on the water in her canoe and trapped by some airless sound design and nothing but Manfredini's score. At least, until we get that jump scare with Jason—hey, he does show up!—and that ending is two great things simultaneously: an absolutely sincere acknowledgment of Alice's loss of innocence and dark passage into adulthood; and a dumbassed jolt of ridiculous horror flick fright that's been expressly admitted to be a rip-off of Carrie's nearly-identical denouement, assuring you that what you just saw was the fun way to approach the gravest and most universal of subjects. It just works: Halloween blazed the path, but Friday the 13th showed the flexibility of the form it had established, and honestly it's no wonder they made like three hundred more of the things.
Score: 8/10
OK, I admit I have been incredibly bad at actually leaving comments lately, because mobile (where I read everything) won't let me anymore, so I have to haul my ass over to my laptop's browser to actually accomplish anything so usually I forget by the time I'm home. But I have been enticed out of my hole by Friday the 13th.
ReplyDeleteIt's so nice to see people warming to Friday the 13th, I agree there is something almost alchemical about the way it works, it's a really unusual movie. And I think it's easy to give it way too much leeway from having seen it too many times, but there's so much stuff that gets to me. Like in the prelude to Marcie's death, she says something like "it must be my imagination" and you see the shadow of the axe rising exactly from where her head is, almost as if she herself conjured it up. IDK, Friday the 13th is just neat.
Yeah, it's a movie where you can identify the consensus criticism of it building on itself until it becomes hyperbolic and barely related to the movie as it exists: it's fairly obvious, for example, that Miller and Curz and Cunningham are probably not capable or interested in generating really sharply-defined and interesting personalities or unique performances, but it also should be fairly obvious that it's not a cast and crew *literally* just dicking around out in the woods, which honestly seems to be the starting assumption for a lot of people watching it. (And perhaps my own, many years ago, unfortunately.) There are definitely completely braindead movies in this world--some of them clearly exist because of Friday of 13th (and, sure, some Friday the 13ths get close)--but they're not *that* common, and anyway this just isn't one of them. It's avowedly junky, sure, but isn't that what it ought to be?
DeleteGreat review. I'm very excited to read your takes on all of these that will undoubtedly more interesting and nuanced than my own when I binged and reviewed the Paramount entries last October. I haven't decided whether to hit the last 4 this fall or take on another series like Nightmare on Elm Street. With how busy I am with "real life" stuff I don't think I have both in me like I'd initially been hoping.
ReplyDeleteBut as much as I enjoyed reading your appreciation here, I still don't really see it. In theory, I get and dig the "campfire story come to life" angle, but it never seems quite so mythic to me as that. Its seams as half-written teen comedy with solid mood and well-crafted gore are too obvious. The characters are too same-ish. The mom twist is too awkwardly bolted on to align with the rest of it. It's not a disaster by any stretch, and I get why people like it (it so elegantly lays out the slasher formula).
You have bumped up my respect for the work Manfredini and Cunningham are doing here, though.
"Friday Week" is a great series title by the way. Absurd out of context, confusing if you don't know that Kinemalogue "Weeks" go on well past 7 days/entries, and just right for a series that includes "A New Beginning" released 11 months after "The Final Chapter"
DeleteDon't forget lazy! If I'd put any thought into it, it'd be Thank God It's Friday, which would be objectively worse.
DeleteRe: myth, one reason I try (I may have failed in the past) to avoid that word regarding F13 is that I do make some hazily-understood distinction between "myth" and "[urban] legend." So on one hand Star Wars or the idea that Iram of the Pillars or Atlantis are out there, versus the "we were making out in my car and there was a horrible noise and when we got home there was a HOOK ON THE HANDLE!" register that the first four Fridays operate in, especially as they get inconsistent. It can be much junkier and significantly more banal and to some extent benefits from being junky and banal, serving somewhat different social or emotional functions. (Or something like that anyway. I'm sure there's some long-established academic distinction that I'm groping towards in an ignorant way.)
I do wonder if that shades into "no, no, you don't understand, it's actually good that it's bad," and I probably use verbiage that arrogates a more mythic scope to it sometimes.
Anyway, I really enjoyed your F13 write-ups. I don't know how pathologically completionist you are, but the more the merrier. I'm... sort of looking forward to the Fridays I haven't seen? I guess? Well, it's only about six hours' worth of material either way.
This hypothetical 90s kids who didn't immediately peg Mrs. Voorhees for the killer because of JASON was me! At that point I'd already seen Fridays 5 and 7 (the Corey Feldman one and the psychic girl one, respectively) and went into Part One looking forward to seeing Jason's first foray of frenzy. In fact, even after Mrs. Voorhees revealed herself to be Jason's mother I was STILL anticipating her to reveal that she'd been secretly raising Jason this entire time and has let him loose to kill those lousy camp counselors. It wasn't until she started chasing Alice around with a knife that it fully dawned on me that she was indeed THE killer in the movie.
ReplyDeleteIt was mind-blowingly cool for me. I had already gotten a sense for "Jason's Mom" being some kind of Friday the 13th background story lore thing before then, mostly from the Nintendo game and recalling another kid mentioning that in one of the movies the "main girl survives by pretending to be Jason's mom," so for me my first viewing of Part One was akin to, like, an amazing cinematic archaeological discovery or something. Good times, good times!
Also, seeing Scream a couple years later, I was proud to know that I would've survived Ghostface's deadly trivia game where Drew Barrymore had failed. >:)
Er, by "the Corey Feldman one" I did in fact mean Part 5 'A New Beginning' even though Part 4 'The Final Chapter' has a lot more Corey Feldman in it. Not sure why I referred to it as such! For me "A New Beginning" was the actual beginning.
DeleteWell, hey, there we go!
DeleteIt does sort of use gender expectations against you*, but that she hasn't existed in the movie previously at all is... a strange structural choice. Not necessarily bad in effect, but definitely a technical demerit.
*Which arguably isn't a "good" trope itself, though I've seen it used much better, notably in a movie I was prompted to think about earlier today. I'm not going to name it, though I'd be astonished if you or anybody reading this hasn't seen it, I'll just say "it's a Batman project." It does it pretty much perfectly, prompting one to slap one's head because they're not even really bothering with a red herring, but it still came off as a surprise to me (at least so I recall).
I've also seen it used horribly, horribly worse in a movie I've recently seen (but also won't explicitly name).
Something I've figured out over time is that Friday the 13th is mostly ripping off the *beginning* of Halloween. "Oh snap! The killer is a mom" is its version of "Oh snap! The killer is a kid." It's not meant to be a whodunnit really, just a point of intrigue.
DeleteAlso as time goes on the more I like that Mrs. Voorhees never appears before the end (though I might've had someone mention her at some point, or at least one more line somewhere about the drowned kid). I also think the gradual reveal was inspired: making it super obvious from Mrs. Voorhees' first shot but never quite making it explicit until she pulls out a knife means that *everyone* in the audience will figure it out at some point in-between and you don't get that "heh, didn't see it coming didja!" smarmy feeling you get from some movie twists. I think the idea is that when you first see Mrs. Voorhees you think, "No... that CAN'T be the killer, right? {minutes pass}...Well, shit I guess she is! Haha, this one crazy ass movie!"
I'm not sure what the examples you're referring to are, but don't tell me, I'll figure 'em out!
(Huh? I could've sworn I had another reply here. Let me try again. If it reappears somehow and I end up with two extremely similar sounding comments, my apologies!)
DeleteOne thing I've learned over the years is that Friday the 13th is mostly ripping off *the beginning* of Halloween. "Oh snap! The killer is a mom" is its version of "Oh snap! The killer is a kid." It's not really trying to be a whodunnit, more just a point of intrigue.
Also the more I think about it the more I like that Mrs. Voorhees doesn't appear before the end (though I would've had someone mention her at some point, or given someone at least one more line about the drowned kid), and I think the gradual reveal was inspired. The way it makes it super obvious from her first shot but never quite making it explicit until the instant she pulls out her knife, it means *everyone* gets a chance to figure it out at SOME point in-between and you don't get that smarmy "heh didn't see it coming didya" feel you get from some other movie twists. I think the idea is that when you first see her you think, "No... that CAN'T be the killer, right? {minutes pass} Well, shit, I guess she is! Haha, this is one crazy-ass movie!"
Oh, I don't know what your examples are referring to, but don't tell me, I'll figure 'em out eventually!
It just got caught in the spam filter, fixed; regret that you had to repost it.
DeleteAs far as first kills in movies goes, this rewatch of Friday the 13th made me finally realize what In a Violent Nature is doing in the end (it's a parody of the demise of Annie, F13's inaugural victim, or at least as far as the main narrative goes). It does not better-dispose me to that terrible ending.
No worries about the spam filter. I'm impressed with myself over how closely I managed to retype the post from memory!
DeleteAnd you're reminding me about 'In a Violent Nature' which I completely forgot about. I gotta check that one out here before I forget again, even if it's more to satisfy my curiosity about it than it is because I expect it to be real good or anything.
Btw, you mention that you felt differently about the cinematography than you did years before (and a specific mention about idyllic summer exterior shots looking spooky) that got me wondering what format you saw it this time around, because Paramount remastered this around 2020 or so and the result was a darkened image (or they increased the contrast... or something I dunno). This web trailer uses the same master: (https://youtu.be/sAzkW7HFh5U?si=9X-eb3nYjoZe6ZHJ)
ReplyDeleteOn one hand, the new look indeed looks scarier IMO, the daytime shots especially. On the other hand, the night scenes are likewise even DARKER than before! On the OTHER other hand, the uber darkness at least looks like it was done on purpose this time rather than by accident, and the film overall has a stronger sense of purpose to its image, if that makes sense.
There's also the matter that it's arguably revisionist, though this is tempered by the fact that so far it hasn't seemed to fully supersede the original brighter image; from what I can tell the 4K and some streaming apps (I know Amazon Prime for sure) are the darker master, but the concurrent regular 1080p Bluray releases still sport the brighter visual (I think they both come from the same 4K scan).
So you can say that Friday the 13th is a land of contrasts. Like, literally this time!
Still relying on the 2018 (cheap) Paramount blu-ray set; the Shout! set, which I believe uses those transfers you mention (it came out--wait for it--October 13th 2020), has always been tempting, but it's ungodly expensive, or at least it feels that way especially when a fully-satisfactory, much-less-expensive option was right there. So I can't speak to the newer version in any of its formats. Kind of seems like mine's better.
DeleteAs for that first watch, years back, I'm fairly certain it was a Netflix DVD; if so it probably dated to, like, the early 2000s, and should have been expected to look like shit. I kinda wonder if maybe that's part of its subterranean reputation, too, since it can be hard to walk back an opinion like "man, this Sean Cunningham guy sure is a joke."
As for other formats, it's fucking bonkers these don't seem to be on Paramount+. Streaming isn't a rip-off, I guess, but man does it often feel that way.
I believe the Shout! box set has a brighter image**, though still remastered (my guess is that it comes from the same *scan* as the dark variant but was put through a separate post-processing, uh, process), as is the case with a newer standalone bluray (for all I know it could literally be the Shout! disc being sold on its own). It seems that the darker version is reserved for formats that hit 4K rez, so that'd be UHD and wherever it might be streaming at the moment.
Delete**Fake Edit: Yeah just confirmed. No clue who "4K Kings" are but their vid here compares the two (https://youtu.be/8Yo_NLUAfRY?si=JXdbcuKq7e8RTN23).
