Trivia: Bill Millin, Lord Lovat's piper, earned the nickname 'Mad Piper' due to the fact that he was spared by German snipers on D-Day because they thought him to be crazy playing bagpipes in the middle of a war.
Trivia: The teenage neighbour to the Hudson sisters is Bette Davis' real-life daughter, Barbara Merrill.
Trivia: Sean Connery started going bald when he was 21. In 'Dr. No' (he was 32 then) and any subsequent movies in which he has hair, he was actually wearing a hairpiece.
Suggested correction: Contrary to popular belief, Sir Sean Connery was not wearing a hairpiece in his first two outings as James Bond. Although he was already balding by the time Dr. No was in production, he still had a decent amount of hair and the filmmakers used varying techniques to make the most of what was left. By the time of Goldfinger (1964), Connery's hair was too thin and so various toupees were used for his last Bond outings.
Trivia: Peter Lawford, who plays a U.S. Senator, was the brother-in-law of three Senators in real life (Jack, Bobby, and Ted Kennedy).

Trivia: There is not a single speaking role for a woman in the entire film.
Trivia: Angela Lansbury plays Laurence Harvey's mother in this film, but in reality she is only three years older than him.
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: "Quackodile Tears" was Arthur Davis' final cartoon as director for Warner Bros. Many printed sources erroneously credit Friz Freleng with directing this cartoon.
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)
Trivia: Towards the end of the film, in various scenes involving trains & railways, if you look carefully, you can quite see that no attempt has been made to disguise the loco's etc. into German locos. You can quite see in various shots 'British Railways' and the British Railways roundel etc. If you know your train stuff, you can quite see all the locos, coaches, wagons etc. are British Railways stock. Also, in the scene in the big station before Dirk Bogarde is captured, and put into a room out the back with his fellow escapees, if you look closely in the background, the station is London Victoria by the way, you can quite see a SR suburban EMU waiting in one of the bay platforms.
Trivia: "Honey's Money" is the only time in the original theatrical cartoons that Yosemite Sam isn't paired with Bugs Bunny.
Trivia: Although Carroll Baker plays George Peppard's mother in this film, she was only three years his senior.

Trivia: In the scene where Robert Mitchum is with Polly Bergen in the boat and picks up an egg and squeezes it. The fear on Polly Bergen's face is real. It was ad-libbed and she had no idea what Mitchum was going to do.
