BLOSSOMS IN THE DUST

Spoiler alert: inapplicable? though Edna Gladney is not, I daresay, actually well-known, plus they make up a whole lot of stuff, so "moderate"

Cardboard Science: Twisted Eden

The Cardboard Science series intends to be a catalog of the science fiction of the past, today.  Science errors will be mocked.  20th century mores will be challenged.  Glories will be recorded.  Films will be, as usual, reviewed.

FORBIDDEN PLANET

The standard by which all space opera is judged, and I doubt I could love it more even if Anne Francis were wearing fewer clothes than she already is.

1956
Directed by Fred Wilcox
Written by Cyril Hume, Irving Block, and Allen Adler (based on The Tempest by William Shakespeare)
With Leslie Nielsen (Commander Adams), Walter Pidgeon (Dr. Morbius), Anne Francis (Altaira), Warren Stevens ("Doc" Ostrow), Jack Kelly (Lt. Farman), Earl Holliman (Cooky), and Robby the Robot (himself) (huh?)

Spoiler alert: severe
Content warning: I do cuss a lot in this one, but the main thing to warn you about is that it's excruciatingly long.  Cardboard Science was conceived as something I could do on the fly, because I'd be mostly discussing B-movies that were barely made at all, and I'm sure that's how it will be as the usual case.  But if we must begin with Forbidden Planet, and I'm afraid we must, the effort must be taken quite seriously.  On the plus side, there are a lot of juvenile jokes, and I split it up into parts so you can quit reading and never return to it.
