The Lost World (1960)

Trivia: Thanks to the money guzzling Cleopatra, the film company that put it out was forced to cut back their budget for other films like this one. Irwin Allen (director of this B grade epic) was forced to use real reptiles as dinosaurs instead of stop motion.

Trivia: In the movie, the native Indians were the bad guys, but in the book, they were the good guys. They were fighting the ape-like species living there, and were helped by the group from England. They however did try to keep the group from leaving the plateau, wanting them to stay.
