Trivia: Shirley Jones was pregnant during the movie. She wore a special corset to conceal this. Director Morton DaCosta did not want anyone else involved in the movie to be aware of her pregnancy. He was so successful, that it was not until the kissing scene on the bridge that Robert Preston (Harold Hill) found out, when he was shocked to feel Jones' baby kicking him in the stomach.
Trivia: The first Carry On filmed in colour.
Trivia: When Humbert first sees Quilty in the mansion, he asks him if he is Quilty, to which Quilty replies with "No, I'm Spartacus. Have you come to free the slaves or something?" This is a reference to the scene from the movie Spartacus, where the slaves who have been recaptured by the Romans all announce that they are Spartacus to try and protect Spartacus when he tries to announce who he is. This is also serves as an in-joke as it was Stanley Kubrick's previous movie, which he made before doing Lolita. (00:03:36)
