Other mistake: When Bond drives into the train tunnel, below the train cart with the jewelry, we see that welding is going on in the other train cart. But that is before the bomb is placed in the hole below the cannon. There is no sign of weldings, and no sign of welding equipment once we get inside that cart.Jacob La Cour
Other mistake: In the scene where Jesse enters Monica's apartment, he consults her calendar to see in which class she is in school that day. There's nothing unusual about this until you look closely at the calendar and see that time time is early/mid August. Did her school's academic year run differently from other schools' years, or was she taking summer classes? The latter doesn't seem likely.
Other mistake: When Harry gets to his vacation spot he is greeted by a dog. A few seconds later the dog is seen lifting his leg to pee, showing his dog is a male. Later on in the film after he returns home after the main killer has killed the second victim, the dog is scratching at the door. If you pause the movie at this moment you notice the dog has a sagging belly with nipples just like a female dog after delivering puppies. (00:48:05 - 00:57:20)killer_sobe
Other mistake: When Norman and Mary are at the swamp, the sheriff hands him the ashtray they found and bates explains that it belonged to Mr Toomey. Mary say "Who"? and the sheriff explains who he is. This makes no sense as Mary knew full well who Toomey was and had no reason to play dumb.Gavin Jackson
Other mistake: When Fatima Blush intentionally water-skis straight up the ramp to the waterfront bar where James Bond catches her, she apologizes, "How reckless of me! I made you all wet!" To which Bond replies with his classic line, "Yes, but my martini's still dry." However, Bond's beige sport jacket (which should instantly show any water stains) is not in the least bit wet.
