Trivia: When Bond first meets Tiffany Case in her apartment, she is playing some music. If you listen carefully, you will notice that it is the theme song for the film.
Trivia: The 'Gambling Ring' Q uses in the Willard White casino is the only Bond gadget (at least up to 'A View To A Kill') which doesn't actually work.
Trivia: It was well documented that the deal put before Sean Connery to tempt him back into the role of Bond was more than generous, a reputed $1 million. So generous a fee was it, that at that time it was listed in the Guinness Book of Records. He donated the entire amount to his charity, the Scottish Education Trust. In addition, United Artists agreed to fund the production of two movies of Connery's choice.
Trivia: In the scene when Bond is taking a bath in his casino suite, Sammy Davis Jr. is on the cover of the magazine Bond is reading. The entertainer appeared as himself in a cameo that was deleted from the film's final release.
Trivia: With the location came its own particular temptations and much gambling took place by the cast and crew during their spell in Las Vegas. Whilst there, however, Cubby Broccoli fell prey to one of a spate of high profile robberies, where his hotel room was burgled whilst he slept and his wife Dana's jewellery was taken.
Trivia: Before being cast as Mr. Kidd, Putter Smith was a jazz musician with no previous acting experience.
Trivia: Two bathosubs were built for the final scene, one with a complete entrance and the other made from concrete, this was to give the sub weight when it smashed into the buildings.
Trivia: Although Mr. Wint and Mr. Kidd are Blofeld's henchmen, they never share a scene with Blofeld in the whole film.
Trivia: During the fight in the pre-credits sequence, Bond places Blofeld's body on a trolley and pushes it into a bubbling lava pool. The 'bubbling lava' you see is actually Cadbury's Smash (instant mashed potato) with added food colouring.
Trivia: The chase in the car park in Vegas was actually the film studio's car park.
