The writers of the movie were childhood friends who had watched the Legends of the Hidden Temple game show during its original run and pitched their ideas while dressed as Kirk Fogg and a Green Monkey contestant. One of the writers dressing as a Green Monkey contestant is a possible reason Dudley bought Noah a Green Monkey shirt and the two brothers, along with their older sister, Sadie, got help from a real green monkey named Mikey.
The feline actor that played the red jaguar found in the Pit of Despair was actually a cougar (it did not have any spots or a flexible jaw).
