Revealing mistake: After Bond and Felix first meet, the background behind Goldfinger is a blatant rear projection. Notice how the couple behind him is completely frozen, as if someone forgot to start the projection running. (00:10:00)
Revealing mistake: When Felix points at Goldfinger's card-game partner, watch the two extras on the right. They stand perfectly still for several seconds before suddenly starting to walk—waiting for the crew's cue. (00:10:04)
Factual error: A crushed Lincoln would be too heavy for a Ford Falcon Ranchero to haul. (01:22:05)
Chosen answer: They're not. Q was just indicating to Bond that these were the wing machine guns, he wasn't stating which was which.
