Trivia: This marked Kenneth Connor's return to the series. His last film had been "Carry On Cleo" in 1964.
Trivia: In the scene involving Terry Scott's "Tarzan" character at the waterfall, the first take of this shot was ruined when Terry Scott's ...er "manhood" fell out of his loincloth, leaving Mr. Scott a little bit more exposed than the script called for. Producer Peter Rogers was later quoted as saying, "If I'd known THAT was going to make an appearance, I'd have put make-up on it."
Trivia: Charles Hawtrey plays Terry Scott's father in the movie, even though he was only 12 and a half years his senior.
Trivia: Second "Carry On" film not to feature Kenneth Williams. He was originally offered the role of Professor Tinkle but turned it down as it clashed with his TV show. Williams was then offered the role of Walter Bagley, which he turned down as being too small.
