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: Angela Lansbury plays Laurence Harvey's mother in this film, but in reality she is only three years older than him.
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.
