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: The role of June was originally intended for Angela Douglas, but she turned it down as she decided to take a break from the Carry On films following her pregnancy.
Trivia: Ug and June's home, seen at the end of the film, was previously used as Yoki's owner's house in Carry on Regardless (1961).
Trivia: Charles Hawtrey plays Terry Scott's father in the movie, even though he was only 12 and a half years his senior.
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.
