Continuity mistake: When Richard Gere is driving through the city in his Corvette convertible, he starts with the top down, then you see the car with the hard top bolted on, then again without.
Visible crew/equipment: As Nikita is dragged from the courtroom by the police, she rolls around. You can see that a pad has been taped to her lower back for protection. (00:11:45)
Plot hole: Detective Mason Storm has been in a coma for a number of years, so how is it that on the day he awakens from the coma, he not only has the strength to move his bed down corridors, but also knows the layout of the hospital?
Continuity mistake: When the mother is putting icing on a cake she destroyed during baking, in the next shot she is shown walking over to Steve Guttenberg's animation table and the icing is gone from the cake.
Continuity mistake: At the end, when Jack shoots the main bad guy, he had already double-tapped somebody, but then shoots at least 5 more shots from a 6-shot revolver.
Continuity mistake: At the end of the movie, Jack parks the car in front of a palm tree and walks onto the beach. The shot changes while he stands there for a few minutes. As the shot changes back to show him walking off the beach, the car is no longer in front of the tree, nor does he drive by during the credits. I hope he enjoys his walk back to Miami.
Continuity mistake: When the girls go to Steppes, Sara's skirt is only just above her knees, yet when she gets home and argues with her Dad the skirt has shrunk to just below her bottom.
Continuity mistake: When Harry Maddox is about to go for a ride with Dolly Harshaw, he reaches for his shirt and is mesmerized by the legs of his other love interest, Gloria Harper. Gloria catches Harry admiring her, with her head turned backwards, cigarette poised near her lips. In the frames immediately preceding this moment, she clearly does not have a cigarette, lit or unlit, anywhere near her.
Factual error: After Robert De Niro awakens, Robin Williams takes him on a ride around New York and Robert is amazed by all the surroundings. The movie is set in the early 1970s, but you can see plenty of vehicles around from the time that the movie was filmed (1990). Notice the square headlights that originally appeared in the late 70's.
Continuity mistake: At the jail bus arrival, the new African American inmate (with orange suit, as the other new ones) is getting off the bus handcuffed and wearing sleek black glasses, next shot, the glasses are gone (handcuffs still on). (00:10:18)
Revealing mistake: During the pirate attack, Rosencrantz sits up in bed, narrowly avoiding a sword that's thrust through the wall next to him. Just before the sword appears, the film jumps a little. It also jumps again just after the sword has been withdrawn and he lies back down. Clearly these two motions (him sitting up and down in bed and the sword appearing/disappearing) are two separate takes that were spliced together.
Continuity mistake: When DeDe walks into Joe's apartment at the end of their date, she places her handbag on the floor a few steps across from the door. When she comes back in to get the bag because she forgot it after she leaves, she reaches for the bag just inside the door.
Other mistake: When Big Boys' men drive through the garage door trying to escape, Dick Tracy, the cops and the goons start opening fire. Yet, nobody seems to feel the need to stop and reload their weapon. They just keep firing without ever running out of bullets.
Revealing mistake: In the beginning, when Hamlet's father is being buried, the new king takes his sword and places it down onto the grave. When he does this, the tip hits first and you can see the blade bend.
Continuity mistake: When Lily breaks into Roy's apartment, she unscrews two small light bulbs in the fixture next to the front door, throwing that whole end of the hallway into darkness. When Roy returns home, he opens the door and the hallway is brightly lit again. (01:32:45 - 01:34:15)
Continuity mistake: When Ralph is running from the hunters at the end and he finds the pig's head on the stick, he stops with his arms spread out a bit. In the next shot, even though you only see his head and shoulders, you can tell that his arms are now straight at his sides.
Continuity mistake: When MSgt McKinny is patting down the prisoners for contraband, his cap changes position on his head between shots. (00:34:55)
Continuity mistake: After Mike punches Billy and pushes him down onto the bar, Billy stands up and shakes the popcorn from his face. The camera angle changes, and now Billy has more popcorn stuck to his face than he ever had before. (00:23:45)
Audio problem: Near the middle of the movie, in the scene when Van Damme's friend Joshua is taking Helene money, you see that the military police have set up a surveillance across the street. They show the policeman's point of view as he is looking through binoculars. You can hear Joshua spray breath freshener into his mouth. The window is closed and they are too far away to hear this on a busy street.
Continuity mistake: When Marvin is trying to get money to pay off the speeding ticket, Bobby reaches into his pocket with his left hand and takes the cigarette out of his mouth with his right hand. Both hands are in motion as this shot ends. The shot then switches to another angle, and Bobby now has the cigarette in his left hand, both arms already at his sides. There was no time to complete this move between shots.
