Tiffany Case made it to the film. Jill St. John captured a lot of Tiffany`s attitude in the film without having to explain what caused her to be so cold towards men. The Spang Brothers gang of crime was replaced by Morton Slumber and his dense goons.
Shady Tree went from being a New York mobster in the book to a lounge act in the film. Wint and Kidd were faceless killers right up until the end of the book. They wore masks, were from Detroit and were more vicious in the book than in the film, though they were still lovers in the film. Felix Leiter made both the book and the film, though in the book he was working on the same case as Bond, but from a different angle.
