Factual error: When Professor Dent tries to shoot Bond at Miss Taro's and Bond is waiting for him in the darkened room, the 'Walther PPK' that Bond is busily screwing the silencer onto, at the beginning of the scene, does not have an external hammer, and is therefore not a Walther at all. It's a Browning 1910 .32 calibre. (00:55:10 - 00:56:35)
Trivia: Roger Moore was Fleming's original choice to play 007, but he was under a network contract for the television show "The Saint". Other actors who were considered for the role of James Bond included Cary Grant, Trevor Howard, Rex Harrison and David Niven - he would play the role of Bond in the spoof 1967 film "Casino Royale".
