Trivia: Although it lasts for only 45 seconds on screen, the stabbing scene in the shower took seven days to shoot and used 70 different camera angles.
Trivia: In 2010, on the 50th anniversary of the release of the film a reunion was held at The Alamo Village. Of the main actors only 6 of them were still alive. 69 year old Frankie Avalon was there and five defectors were there with Mrs John Wayne. Richard Widmark (Jim Bowie) had died in 2008.
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: This film is loosely based on the Scopes Case, where in 1925, a Tennesee subsitute teacher was accused of violating a law that prohibits the teaching of Darwin's theory of evolution. This case pitted Christian fundamentalists (who rejected the theory of evolution as they felt it contradict their literal belief of the Bible) against supporters of evolution.
Trivia: In the film, Pollyanna shows Reverend Ford (when he practices his fired up sermon in the field) the locket with the quotation "When you look for the bad in mankind expecting to find it, you surely will," inscribed upon it and then credits the adage to Abraham Lincoln. Seeing an opportunity, Roy Disney, Walt's brother and Disney Studio CEO, had thousands of promotional lockets with those inscribed words (duplicates of Pollyanna's charm bracelet as well) produced and sent to gift shops. By a stroke of luck, while on a family trip to Disneyland, the screenwriter/director, David Swift, happened to notice the locket copies in one of the Disney gift shops and contacted Roy at the Disney Studio and told him to recall all the lockets straight away, because he deliberately fabricated the quote for the film - Abraham Lincoln never said it.
Trivia: To make the office appear larger than it was, the team used forced perspective - adult actors at the front, with child actors behind them, and tiny desks with wire-operated dolls at the back.
Trivia: When a rider is speared in the back by an Indian, he yells the Wilhelm scream.
Trivia: In the opening title card, you will notice there is no "Story" credit. Michael Maltese was the story writer, but as he had left Warner Brothers for Hanna-Barbera, his name was removed from the credits.
