Continuity mistake: Dick Jones brags (admits?) to Robocop, "I had to kill Bob Morton because he made a mistake. Now, it's time to erase that mistake" while Robocop is crouched on the ground, not only looking away from him from across the room, but also Robocop's eyes are in a vertical position. In the playback, Jones is facing the camera as though it were videotaped or filmed in a studio. (01:10:50 - 01:35:10)
Continuity mistake: When they steal the truck at the mall they have to hot wire it to make it start. Later at the San Andreas fault scene where the road ends, in the same truck, he turns the truck off with the key.
Continuity mistake: In one scene after Hutch is beaten up on the bus, he has no facial injuries. Then in the next scene, they are back.
Continuity mistake: Agatha's nightgown strap switches between hanging down on her arm, or being up on her shoulder, normally.
Continuity mistake: When Jesse is going to race Johnny Tran at Race Wars for pink slips, and Johnny Tran pulls up in his Honda S2000, Tran has on a black long-sleeved shirt. When the camera goes from side to front view, Tran has on a black tank top. (01:12:41)
Continuity mistake: When Portnow meets with Bishop at the church, in the first closeup of Bishop's crossword puzzle the word "MUD" is the second word across at the top, and at the center of the puzzle the 4-letter word "GEAR" is written in the 5-letter answer - with the fist space left empty. However, in the next closeup of the puzzle, now the word "ETA" is the second word at the top and "MUD" is the third, and the word "GEARS" has the "S" added, with the letter "G" started properly in the first space of the answer. (00:10:15)
Continuity mistake: When Danny & Debbie are having their New Year's dinner at home, the champagne foam instantly disappears in the very next camera angle after pouring it.
Continuity mistake: The morning after Christian brought a drunk Ana back to his hotel room, she is sitting in bed eating some breakfast. The piece of toast she is holding keeps changing shape, having one bite taken out of it, then two, then one again in a different pattern.
Continuity mistake: Near the end of the movie, when Oppenheimer is being interrogated in the small room, his lawyer is on the phone (we later find out it's Kitty). In a wide shot, he gives Oppenheimer the phone, and he puts it to his left ear. The next shot is a tight shot of Oppenheimer's face with the phone to his right ear.
Continuity mistake: When Richard and Francoise are making love on the beach. They begin kissing deep under the water and continue all the way to the top. When they reach the surface they can stand up in the water which appears to be waist-level.
Continuity mistake: When Danny gets shot at the end of the film, his paper flies out of his hand. But the very next shot of him shows that the paper is still in his hand being held over his head while he falls backwards. In one of the following shots the paper is back on the floor, but it's on the opposite side it should have been when it flew out of his hand. It's all shown in slow motion and it's very obvious.
Continuity mistake: In the 'Gaston' song sequence, near the end, Gaston is sitting in his huge antler chair with Lefou. In the wide shot, there is a bear rug behind the chair. The camera does a close up of Gaston, then in the next wide shot, the chair is on top of the bear rug. Also, after this, Gaston gets up off of the chair and in the next shot, both the chair and the rug disappear completely. (00:29:20)
Continuity mistake: Arnold goes to the gay bar to solicit the help of the guy he saved at the beginning of the movie. The guy is wearing a white shirt and a vest black/gold lamay. During their conversation he takes off the vest, then it cuts to another bartender. When it cuts back the guy has the vest on, another shot and the vest is off again. (00:08:05 - 01:10:50)
Continuity mistake: Where Swazye and Moore are at the pottery wheel, seconds after their hands and arms had been smeared with clay, they're clean.
Suggested correction: The director explained this in the commentary. The scene where they are clean isn't meant to be immediately after the clay pot scene. It was just the same evening.
Continuity mistake: When Adam Banks is playing in one of the games, he scores a goal and his teammates on the bench stand up and cheer when he scores. Problem is, Adam Banks is on the bench too.
Continuity mistake: About 10 minutes into the movie, when the truck is chasing the 2 college students in the car and starts ramming them, the bumper and the trunk is smashed in. The shot changes and shows the car's rear end and it is in perfect condition. This repeats at least 3 times.
Continuity mistake: In the kitchen scene, when Frank's parents are arguing, the clock reads about 6:45 and then in the next shot, it is 6:15.
Continuity mistake: Why does the Twinkie Kevin Bacon eats disappear immediately? If things that go into him disappear, when they give the needle to the gorilla, you shouldn't see the needle point when it is stuck in her arm.
Continuity mistake: In the first scene when Maverick enters the airbase on his motorcycle it is mid-morning based on the sun and shadows. When he takes off in the test jet it is pre-dawn.
Suggested correction: The movie sequencing/reveal is shoddy for this. Prior to him uncovering the motorcycle and heading out he slaps the calendar on the wall where it says, If I recall, "Mach 8." the day before on the calendar says something like "training" or "physical test" or something (I honestly forgot). That happens the first day ("afternoon") as shown with him on the treadmill; he sleeps on-base to get up "pre-dawn" and that's when the admiral arrives and he takes off.
This shot is likely referring to the fact that at Mach 10 he's travelling so fast towards the west that the sun (which only just set) appears to be rising again, as he outraces the darkness.
Travelling that far west would bring aircraft and pilot well over the pacific. No chance to find a lift back there.
I've watched this movie many more times since my comment. The runway assigned is "21", which has a heading of 210°, roughly southwest. This puts him facing the setting sun, but at his speed he's covering such a distance that he's actually seeing it "set" again. Even with the turn, the POV of the breakup appears still heading west. Somehow he ends up in rural (Northern?) California, walking all night to arrive at the diner for breakfast.
Continuity mistake: When the cow blows by the truck, the truck is driving down an empty dirt road with water on both sides. During the shots of the occupants, the road behind the truck is paved and dry. Also in one of these rear shots a truck (Red Chevrolet Blazer) drives by in the opposite direction. (00:42:25)
