Other mistake: In the scene where hundreds of men burst into the place where Penelope Cruz gives her cooking lessons, you can see that one of the waitresses drops the plate she is holding a split-second before the guys swing the doors open and rush past her.
Other mistake: The radio station had no power or telephone lines anywhere in the vicinity, and the lines would not have been buried in 1937. A telephone is seen on the wall inside the building, yet it couldn't have been connected to anything. There wasn't a generator to power the radio transmitter, because it would have had an exhaust pipe through the roof, nor was there any adjacent building to house a generator.
Other mistake: When Bullet-Tooth Tony goes to 'open the dog' in order to get the diamond out, and then Vinny confesses that he has it, the dog starts to go crazy and in one scene proceeds to pull Sol's jacket off. If you look at Bullet-Tooth Tony's face, he is laughing at how crazy the dog is (this would have been a real-life giggle because the character is quite serious at that moment in the film).
Other mistake: When Brian and Jake are sitting against the fence just after being beaten at basketball, Jake asks why Anna called Brian and not him. Brian yells "What are you, in the eighth grade still? Fynn before Shram." When he says "Fynn" which is his surname, he points at Jake, and when he says "Shram," Jake's surname, he points at himself.
Other mistake: The wet nurse that cares for the newborn Titus is pregnant when she is hired. She is far enough along to be producing milk, yet doesn't give birth until Titus is a year old.
Other mistake: When Honey Whitlock throws a grenade during the shoot at the Baltimore Film Commission meeting, you see the explosion before the grenade actually falls all the way behind the wall that the explosion supposedly comes from. I think the pyrotechnics guys let the explosion off a little early.
Other mistake: There are references to there being 50 representatives in the pageant, however "Miss District of Columbia" is seen numerous times during the early stages of the pageant.
Other mistake: In the scene where Tzekel-Kan reveals the big tiger thing, he is on his knees facing it. He says "do as I command" and raises his right arm and the tiger raises his left arm. The tiger and Tzekel-Kan should both raise the same hand because the tiger is built to mimic Tzekel-Kan's exact moves.
Other mistake: During the landing, when Jerry is getting Ethan and Roger out of the shuttle using the escape pole, the two people going out (presumably the stuntmen) look to in fact be jumping out the hatch, instead of just being pushed/thrown by Jerry.
Other mistake: The second time Virginia goes down the slide in the 9th Kingdom, you can see that it is a stunt double hurrying to get off at the end.
Other mistake: The end credits show Annie, Clarabel, Bertie and Harold under the voice cast for "the trains", but Annie and Clarabel are rolling stock, Bertie is a road vehicle, and Harold is an aircraft, respectively.
Other mistake: More than halfway through the film, after Gwen's room-mate has died of an overdose, she rings her sister on a phone that is not only "Emergencies Only", but it has no numbers on it. So how did she dial out?
Other mistake: When Martha May is getting ready to put up her lights with the cannon, she pulls a charging handle, and starts firing. If you watch closely, you see a lit string of lights come out, but the spool that they're on isn't moving, or lit up. Then after all of the lights are out, it still fires several more times (watch the aiming indicator- it continues to flash with the sound).
Other mistake: When Elliot the genius homosexual and Allison arrive at his apartment he hangs her wrap on the arm of the statue. He then begins to take off his overcoat and hangs it on the other arm. There is a cut to another angle and the coat is already hung on the arm and he is sliding out of it. There was not enough time for this transition to happen. (01:02:15)
Other mistake: When Orlando Jones uses the stickup for his hands, in the next play his hands are very clean, and if you have ever used it, you know what I am saying.
Other mistake: Deebo's name is spelled with 2 e's, but throughout the movie the subtitles spell it with only 1 e.
Other mistake: When the airbags are deployed on the "indestructible" Peugeot they stay inflated, making it difficult to get the driver out of the car. Comedic effect aside, real airbags do not deploy when the vehicle is stationary or hit by a hand on the roof and also begin to deflate immediately after deployment due to the gasses cooling and leaking out of the vent(s) in the bag. A previous correction speculating about modified airbags cannot be proved and is irrelevant as they are a legal safety feature of the vehicle and cannot be modified.
Other mistake: At the beginning, the police say, "Mona Deary is dead." But how do they know that? The car isn't hers, it's her son's, and it's in the water. It's only when the car has been dragged out of the water that they can see the true picture.
Other mistake: Jack's friend Bill (Tom McGowan) was scheduled to have heart bypass surgery, but he is bowling the next day or shortly thereafter.
Other mistake: When the cow is seen on the road, note the black and white patterning on its hide. At the end, when you see the cow in a neck brace, it has different patterning. (00:29:50 - 01:44:35)
