Continuity mistake: As Harris and Trudi are driving down the freeway, while having a shootout with other drivers, Harris hits a water container on the truck next to them and water sprays across his windscreen. In the next shot (which is wider) the windscreen is completely dry and remains that way for the rest of the scene.
Revealing mistake: At the beginning of the film when a Judge is thrown out of the airplane, you can see a parachute is attached to him.
Visible crew/equipment: When the cop car chasing the tow truck does a complete flip in the air, a roll bar is clearly seen where there was none before.
Continuity mistake: At the end of the movie, when Woody Allen and Bette Midler are both using the payphones Bette Midler says, "Mine was from Hans," and she's looking at her planner. In the next shot, however, she's on the phone, having already dialed Hans' number.
Continuity mistake: In the "Corn Scene" when Pepto is eating with the bums, and he tells the bum that he has a piece of corn on his face, during cuts a white plastic knife suddenly appears beside his bowl.
Continuity mistake: Towards the end of the movie, when Dr. Alex Tremor goes to see Marina Lemke, he enters her apartment and it is light outside. He stays only long enough to have a 5 minute argument with her. As he exits her building, it is very dark.
Other mistake: After Nora leaves with the wrong bag, Snaps calls the Underwood home to ask someone to come over and switch them back. Later, Nora herself returns and Aldo makes the switch for her. Then the Underwood chauffeur comes to trade the bags, and Aldo does this for him. But Aldo would've known that Nora had already retrieved the correct bag, so why would he change them back?
Visible crew/equipment: During the scene where the grandmother and the monsters stop at a variety store in the tinted bus a camera man can be seen. As the bus pulls away, you can see the camera man standing there filming the scene quite clearly in the reflection of the bus windows as it pulls away. (00:24:30)
Continuity mistake: When Oliver puts the divorce papers in his jacket he puts them in his LEFT hand breast pocket. When he hands them to Charlotte he takes them out of his RIGHT hand breast pocket.
Continuity mistake: When Alec Baldwin finds Kim Basinger in Las Vegas, she is wearing a white dress with thin straps. One strap is continually off her shoulder - except for one shot after he has followed her into her dressing room. They shoot her back, and both straps are up. All other shots have the one strap off her shoulder.
Visible crew/equipment: Toward the end of the movie Curly Sue comes back home from the orphanage. She sees the letter from Bill and begins to walk slowly to the living room - look left to the screen and you will notice something drop from above kinda looks like something silver, maybe a boom mic.
Visible crew/equipment: In the scene where Jack approaches Parry's bed, a crew member is seen on the right hand side of the shot wearing a walkie talkie. He inches out of frame in 3 or four seconds. (01:51:05)
Revealing mistake: When the assistant warden explodes after his body starts inflating due to the warden shooting him with the elephant bullets, in the close-up shot of his head exploding, we can see that his head has been replaced with a fake dummy head. (01:23:18)
Character mistake: When the Tradewind arrives at the island, captain Hilliot says, "They might not be civilized," to which Richard replies, "Civilized: c-i-v-i-l-i-Z-I-D."
Character mistake: In the very first scene, in the first shot you see a sign in Spanish that says "NO PASE por orden del departamento de arquiologia". The correct Spanish word is arqueologia.
Character mistake: We see in a flashback (so, early 1600s) the protagonist with his mother in Ruen, back in motherland France. She tells him she is praying to St. Joan (d'Arc; they are in front of a statue of hers). Joan d'Arc wasn't canonized until the 20th century. You could argue that in the eyes of the laymen she was already considered a saint. However, her son does not object and considers her a saint as well, doubling down on the statement even later on in Quebec when he does not have to humour his mother, and he is a Jesuit. He obviously should know better. (00:35:25)
Factual error: Hawking explains how time slows as one approaches a black hole's event horizon. To illustrate this a CGI-animated analog wristwatch is shown ticking away the seconds progressively more slowly. It's the kind of watch that ticks intermittently: once each second the hand sweeps one second-long increment around the dial and then waits one more second to sweep another increment. In the animation, the frequency of the ticks lessens, but the speed at which the hand sweeps each increment stays the same. To be consistent, the sweep-speed needs to slow down just as much as the tick-frequency. (00:36:30)
Continuity mistake: When the red haired woman is undressing to enter the jacuzzi to kill the guy, her red dress is either on top of the white robe, or next to it, depending on the shot.
Continuity mistake: The little girl who was missing after falling off the cliff, suddenly shows up again after the evil woman is struck by lightning and is seen standing with the other children to react. But then she's gone again only to then show up with Santa.
Other mistake: Jack gets hit in the face by a car trunk but when he wakes up later there's no cuts or bruises on him.
