Continuity mistake: When the Joker's henchmen are trashing the museum, one guy puts red handprints all over a portrait, later the Joker walks by the same portrait and the handprints are gone. (00:59:55)
Continuity mistake: When chasing Jamie in the woods, Mikey's headlights go from normal chevy headlights to off-road high beams.
Continuity mistake: Notice Marty's hair in the scene when he's playing "Johnny B. Goode." It's quite larger than when he says, some seconds later, "I guess that you're not ready for it yet." That's because when he says that, it's a recycled shot from the original BTTF, whereas most shots showing he's playing the guitar are newly made for BTTF2. However, Marty's hair is considerably longer in the new shots. (01:27:19)
Continuity mistake: When Spock, wearing rocket boots, is in the turboshaft carrying Kirk and McCoy on either arm, he fires the booster rockets, thus propelling the three of them up the turboshaft. If you watch carefully, the deck numbers in the background as they rise upwards go as follows: 35, 52, 64, back to 52, 77, 78, and then 78 again! Not content with one goof, Kirk and McCoy can quite clearly be seen with their feet dangling in mid air, not on Spock's boots. They aren't exactly clinging to him either, more like leaning against him. Surely Kirk and McCoy would be unable to hold onto him!
Continuity mistake: At the end of the movie, when Riggs is in the cargo area, a gunman shoots at him, he rolls and starts emptying the clip into him - you see the bullet holes in the gunman. But as Riggs is face to face with the gunman, the holes disappear.
Continuity mistake: In Ellen Barkin's apartment, Al Pacino accidently knocks a postcard off of the fridge. A few seconds later, it's back where it was, though nobody picked it up.
Continuity mistake: Early in the film Bud throws his wedding ring down the latrine and then retrieves it with his right hand so it is covered with the blue disinfectant. In a (much) later scene, Bud has a blue right hand, despite not having had one in the intervening period. (01:44:48)
Continuity mistake: When Beck meets Webly on Christmas Day, Webly takes his glasses off and throws them on the desk, but in the next shot (from behind) he is still wearing them. (00:16:50)
Continuity mistake: When Tango and Cash are playing the "good cop, bad cop" routine with Requin, the tape on Requin's mouth is almost off, but in the next shot the tape is OK.
Continuity mistake: Towards the end of the movie Dave takes Walley's jacket and uses it to help them slide down a cable. Before they slid down, Dave tells Walley to hold on, and Walley asks if they're going to be above the ground. Dave tells him no, and off they go. However, Dave is deaf, and reads lips, and Walley is standing behind him when he asks the question. So how did Dave read his lips if he wasn't looking at him?
Continuity mistake: There is no knife on the table when the wife enters the kitchen at the very end, however, she walks straight to Louis, hugs him and then magically a knife appears at the edge of the table which she picks up and uses to stab him (implied - the movie actually ends at that point).
Continuity mistake: In the scene on the plane, you see Bond hanging at the door on the right side of the plane. In the next shot, you see the plane making a left turn. In the following shot, Bond is still hanging on the right-side door. Shouldn't he have fallen into the plane?
Continuity mistake: While Tom Hanks is driving to the motel after leaving the fish packing plant, scratches are on his face and blood is on his ear. When he pulls into the parking lot of the motel, the scratches are gone.
Continuity mistake: In the scene where they are discussing why Dalton fired Mr Wesley's nephew (upstairs in the Double Deuce). Mr Wesley's nephew threatens Dalton with a knife and when Dalton takes a swing at him, there is blood on Mr Wesley's nephew's face way before contact. (00:34:05 - 00:38:00)
Continuity mistake: In the shot where the Roses are hanging in the chandelier, Kathleen Turner goes from being barefoot to having some type of shoe on and then back to barefoot.
Continuity mistake: When Andre Toulon puts Blade into the suitcase, near the start of the film, Blade's hook is on his right hand but it is attached to his left hand in all other shots of him. (00:09:45)
Continuity mistake: When Alice and Mark are collecting all the sheets from the floor, Alice looks at a sheet about Amanda Krueger. Then in the next wide shot as her dad calls for her, all the sheets are in a pile to her right. Then in the following closeup, she starts picking up sheets of paper from all around her. (00:53:35)
Continuity mistake: During a car chase, the "killer" is rushing a little girl to the hospital. As they pass the sign, it reads (in English) "Scared Heart Hospital" - instead of "Sacred".
Continuity mistake: In the race for King of the Mountain, Anthony wipes out and begins cursing. Then, in the next shot, he has to spit out some snow before he can curse again.
Continuity mistake: During the "exciting" conclusion, Investigator Natsuo runs toward the villain's vehicle, jumps, and kicks through the windshield. Besides the fact that there are some poor special effects at work, watch this quick shot closely. As he is flying through the air in that split second, the villain's car changes colour! It is quite obvious, as the car goes from a dark red color to dull grey.
