Continuity mistake: Bernie gets shot underwater with the spear and can't let go of the chest. But when they take the vest off Larry to float Bernie up to the surface, Bernie takes his hand off of the handle to get the vest on.
Plot hole: A nuclear armed stealth fighter is accidentally sent back in time to 1940's Nazi Germany. After the Nazis capture it, two days later they drop a nuclear bomb on the United States. There are several basic problems here. Firstly, if the Nazis captured advanced technology, wouldn't they spend more time taking the plane apart and interrogating the captured pilot? How on earth did they manage to train a pilot to fly the stealth in such a short length of time? And how did the stealth fighter manage to reach the U.S. from Germany when in-flight refuelling was unknown then?
Revealing mistake: When Wayne has gone to the church for Cassandra and finds out that it is actually the one across the street, he walks across between them. If you look where the sun is coming from, his shadow is actually in the wrong direction when he is between them. (01:18:10)
Deliberate mistake: Within the final crash scene, in the shot where the flames are first shown exploding through the cabin, you can plainly see that all the seats (especially the aisle seats) are empty. In addition, this shot takes place after several shots depicting cabin breakage, and debris flying everywhere. Here, nothing is flying anywhere, and nothing is broken.
Continuity mistake: When the waitress at Dottie's seduces Butch, the degree of boob exposure varies depending on the camera angle (not only due to perspective). (01:17:15)
Other mistake: During Waverly's second chess match, her opponent says "check" (and play continues) even though it is checkmate.
Continuity mistake: When Walter (Robert Duval) is shaving Frank (Richard Harris), notice how the shaving foam on the upperlip disappears before the upperlip has even been shaved and then suddenly reappears in the next shot where the upperlip is shaved.
Continuity mistake: When Joe, the Heisman candidate quarterback, jumps his Harley off of a dirt cliff, one camera angle is from below as the bike is in the air. The angle clearly shows the bike is different from the Harley he started and finished with. Most noticeable is the fact that the tyres on the stunt bike are knobby enduro tyres, but later when the bike is stopped, you can see the smooth street tyres are back again.
Revealing mistake: After Naomi is thrown from her balcony in the beginning, the blood on her face has beaded down her face and is staining her blouse. This is impossible being that the injuries she received happened less than a second before and she landed face down after going through the glass, so the blood couldn't have ran down her face in that direction.
Continuity mistake: In the scene, towards the end of the movie, Billy Baldwin is running down the street chasing the cab that the girl he wants is in. His shirt changes from having a pocket to not having a pocket. The colour also changes from yellowish to more brownish.
Other mistake: After Molly crashes the taxi, she is standing outside in the bitter cold. Yet you never see her breath (vapor) when she is speaking or when she is huffing and puffing when confronted by the wolf.
Continuity mistake: When Bessie is examining the cards she found under the desk, they constantly shift relative to each other between shots. (00:23:05)
Continuity mistake: This movie has many flashbacks to the late 1970s or early '80s, but in one scene the little boy is in his pajamas and it depicts symbols of NHL teams. Half, if not most of those teams were not around at that time.
Continuity mistake: When the bus is coming to pick up Alfre Woodard as she is finally meeting her son, we see Robert Downey, Jr. briefly touch her on the shoulder. Since she's a soul, this is impossible.
Visible crew/equipment: When Emilio and Sam arrive at the "Squealer's Motel" and get out of the car, the camera man and sound man are visible in the window behind them as they walk towards the group of police.
Continuity mistake: In the hotel scene where Darby calls Gavin to give him the instructions to meet her the next day, he eats one of the chocolates on his pillow and throws it down. They show a close up of the chocolates. After Khamel murders Gavin, he walks to the bed, pulls the recording device and eats one of the chocolates. They are now in a different spot on the bed. (00:59:55 - 01:00:25)
Revealing mistake: At the end of the movie with Matt Cordell (Maniac Cop) chasing after the detective in a police car while being set on fire, you can see the safety goggles under his mask in several of the changing shots in this stunt scene.
Factual error: During the scene where Bruce leaves his girlfriend's parents home, it's raining. He leaves in a huff on his motorcycle and you can clearly hear the sound of screeching rubber on the pavement. Peeling out and making this sound would not have been possible in a rainstorm.
Audio problem: In the scene where Tyler is preventing Whoopi Goldberg from sitting down by asking her stupid questions, there is a part where Frankie says, "Oh you're gonna get jumped after school Tyler." When the word "Oh" is heard, his lips aren't moving.
Continuity mistake: When a nude Brad Pitt is digging a big hole, at first his skin is clean, then in an instant with a camera angle change he is covered in dirt and sweat.
