THE NAKED JUNGLE
A throwback even for 1954, this romantic creature-feature does the romance better than just about any "proper" sci-fi film, and does its creatures fair justice, too.
1954
Directed by Byron Haskin
Written by Philip Yordan, Ranald MacDougall, and Ben Maddow (based on the story "Leiningen Versus the Ants" by Carl Stephenson)
With Charlton Heston (Christopher Leiningen), Eleanor Parker (Joanna Leiningen), Abraham Sofaer (Incacha), William Conrad (The Commissioner), and John Dierkes (Gruber)
