New this month Audio problem: In the beginning, when Murtaugh's daughter comes downstairs in the black dress the dialog is dubbed in. After the spin, she's talking but she doesn't move her mouth (even before the spin she isn't in sync). Her little sister replies and doesn't move her mouth either.
Revealing mistake: Riggs handcuffs himself to the depressed businessman. They jump off the building but they're not handcuffed to each other anymore. They used plastic cuffs which could separate during the stunt in case anything went wrong. They break just as they jump, so they grab each other's hands to stay in contact. After they land the cuffs are attached again.
Continuity mistake: In the scene where the girl jumps to her death from the balcony, it shows her hitting the car towards the right halfway onto the windshield. Then in the next shot, it shows her laying right in the middle of the roof of the car.
Visible crew/equipment: When the car crashes into the bus and lands on its top, you can see a big square hole cut out of the car's underside.
Continuity mistake: At the end, when Riggs is at his wifes grave, it's supposedly raining. In one shot you see Riggs' hair is dripping wet, and when you see him bend down to put the flowers on the grave in the next shot, his hair is dry, and in the next shot it's wet again.
Continuity mistake: During the scene where the General is escaping in the car and Murtaugh shoots the driver. When the car is hit by the bus on the avenue you can see part of the device that makes the car flip over and roll away from the crash.
Continuity mistake: There is a scene where Riggs and Murtaugh are driving in a car, and the column shifter keeps going from park to drive and back.
Continuity mistake: When Hunsaker's shot, his eggnog gets all over his tie and shirt. When the camera angle cuts to Murtaugh's reaction, Hunsaker's shirt and tie are clean and there is no eggnog pouring from the container. Also there is no hole of any kind in the glass door behind him in which the bullet made.
Continuity mistake: In the scene where "the General" and his driver were fleeing down the alley, the driver is shot. The general takes control of the wheel and carries on driving, but the car is in park...
Continuity mistake: The Christmas illumination on the balcony of Amanda Hunsaker's hotel room is arranged in three different ways: In the first shot, before she takes drugs, it is attached to the side of the railing. When she steps out, the lights are hanging about 10 inches below the railing, like they are later when Murtaugh searches her room. And when she climbs up to jump the bulbs are directly hanging down from the railing.
Continuity mistake: As Riggs exits the car, he takes the cigarette out of his mouth. The camera angle chages to show him standing outside the car, handling his pistol, and the cigarette is back in his mouth, with no time to put it there and the audio indicates the shots are consecutive time.
Continuity mistake: When Riggs sees the car with Mr. Joshua coming he pushes the hooker away and starts running, but when he is shot at it looks as if he was standing with his back to a shop window. Accordingly, his bullet-proof vest has holes in the front, but then his red jacket has only holes in the back.
