Sean Connery was paid $5,600 for his role in this movie. When asked to play in the next Tarzan movie, he said he couldn't because "two fellows took an option on me for some spy picture and are exercising it. But I'll be in your next." The "spy picture" was Dr. No.
Cheetah appears only during one line ("So long, Cheetah"). This is because the chimpanzees brought from England to Kenya for the filming were so terrified of the jungle night noises they wouldn't perform.
Producer Sy Weintraub also wanted Anthony Quayle to come back for another Tarzan movie, but Quayle had been offered a part in Lawrence of Arabia after having been seen in this film, and couldn't accept.
This was the first film for producer Sy Weintraub. He would make Tarzan adventures, including the popular television series, throughout the 1960s.
