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.
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)
Suggested correction: Correct to say it's not a PPK, but it's not a Browning either - in a close up one can see the Beretta logo on the grip.
First off, it is certainly not a Beretta. That's not the Beretta logo (3 arrows), but it's the Fabrique Nationale logo (stylized FN). Plus the Beretta has an external hammer and the gun in question does not. It is indeed a Browning 1910 (which is manufactured by Fabrique Nationale. Finally, it is not necessary to submit a correction for mistakes that are accurate but have one or two words wrong (not that this mistake had any words wrong).
Factual error: Bond is worried that Dr. No has picked up the sails of Honey's boat on his radar, as indeed the good doctor has (in the movie), but radar systems cannot detect cloth or a wooden mast. (01:01:40)
Suggested correction: Depending on the quality and power of the radar set, wood ships can be detected. A military warship radar, even in the early 1960s, could detect a wood sailboat.
Continuity mistake: When Bond leaves the hotel to go to Governor's House he has no pocket square. At Governor's House he has his pocket square. Then in the next scene at professor Dent's, the pocket square is gone again. (00:25:30)
Revealing mistake: Bond, Quarrel, and Honey are supposed to be walking through a saltwater river and yet none of them seem to react when coming out of the water with their eyes open so obviously it's fresh water used in the river. (01:15:10)
Suggested correction: Freshwater... river.
