Revealing mistake: That isn't Joan Sims in the shower as seen from above. The stand-in doesn't remotely resemble her.
Revealing mistake: When Valerie Leon is about to blow a dart at the "Head Chef", look carefully and you can see there are already two darts in the Chef's mask.
Continuity mistake: When the jungle boy says "woman" to June, he points to his chest and puts his hand to the ground. In the next shot, he is pointing to his chest again.
Prof. Inigo Tinkle: I'm flabbergasted! My gast has never been so flabbered.
Trivia: This was the second Carry On film not to feature Kenneth Williams. He was initially asked to play Professor Tinkle but had to turn down the role due to scheduling conflicts with his own television programme, The Kenneth Williams Show. Williams was then offered the role of Walter Bagley but turned it down, stating that the role was too small for his liking.
