Revealing mistake: When headshots are shown of Bond inside the Aston Martin at the Auric Factory, and when he drops Tilly off at the gas station, you can see the three holes left in the headliner of the car where they have removed screws for the interior sun visor. (00:37:50)
Revealing mistake: When Bond's car crashes at the Auric factory, and the Mercedes comes to a stop, you can see the cut edges of the colored paper covering the headlights of the Mercedes. (00:45:50)
Revealing mistake: When the small jet taking Bond to Washington is shown taxiing away from the assembled VIP the engines are not running (no exhaust) and one can faintly see a tow cable pulling the plane to the right.
Revealing mistake: At the beginning of the film, Bond shoots his rope gun to climb over the wall. If you look closely, the rope he shot didn't even come out of his gun. It comes from off the left side of the screen. Very visible in slo-mo, or paused
Revealing mistake: When Bond is at the hotel at Miami, in several scenes you can see that film was shot at a hotel, and then the editors placed the card game opponent's figure in the film. The filming of the figures is a lot clearer and crisper, while the background looks like a homemade film.
Revealing mistake: When Oddjob throws his hat at the statue and the head comes off the head falls on top of the arm and breaks it. Obviously this was not meant to happen as there is a quick edit in the film before the arm falls completely off (notice the trees behind the statue suddenly freeze).
Revealing mistake: When the CIA guys are following Odd Job to the airport in "Kentucky" there are several indicators that show they are in Florida. One is a big sign that says Opa Locka, which is north Miami.
Revealing mistake: Bond's unconscious body falling out of the car at the end of the car chase is obviously sped up.
Revealing mistake: When Oddjob throws his hat at the statue and the camera cuts a close up of it, as the hat goes by the head, you can see the seam (in a freeze frame) where the head is propped up by the filler used to disguise the break. Also, the brim of the hat where the blade is, passes about two inches above the break. Therefore, were it possible, the brim doesn't cut the statue.
