Continuity mistake: At the end of the film, when the Army are arriving on the island, the amphibian plane is beached, with the nose facing the beach and the camera. In the next shot, when we see the same plane again, it has been moved out about 50ft, and turned round. (01:26:00)
Continuity mistake: Towards the end Arnold is firing a gun, and the length of the ammo belt changes. They show the ammo almost gone and then after an edit it's dragging on the ground. (01:16:00)
Continuity mistake: At the end, where Matrix kills Bennett by throwing a pipe through him (OK sure, but let's just pretend). The pipe goes through Bennett, and into a steam pipe behind him. Then steam pours out of the Pipe that Matrix threw. Now what happened to all of the flesh, bone, skin, and blood that was inside of the pipe? (01:24:00)
Continuity mistake: When Matrix boards the plane towards the beginning of the film, it is early evening - the sun is shown to be low in the sky, casting long shadows. Once he has escaped from the plane and is making his way back across the runways into the airport building, the shadows are smaller and more intense, showing the sun is more directly overhead - therefore it has suddenly become much earlier in the day. (00:21:50 - 00:24:15)
Continuity mistake: The police van with Matrix inside pulls away from Cindy and drives for about 30 seconds including the fact that Cindy fired two rockets at it, and, yet, when it stops it is still much too close to where they began and this is even after someone misfired a rocket at them.
Continuity mistake: Matrix slams the caterpillar into the gun shop through the metal gates and continues for several seconds, it appears that the metal gates are knocked down a few times. Also, the caterpillar winds up very close to the window even after Matrix drives it for several seconds once inside.
Continuity mistake: When Arnold is crashing into the gun shop in the caterpillar you can see the camera to the rear (a black round one) and then also the camera at the front can be seen as a yellow box, attempting to be disguised as part of the engine block. These quickly disappear in subsequent shots.
Continuity mistake: During the motel room fight scene when Cooke crashes into the other room, the door separating the rooms changes between shots. When he first crashes through the door it's just a wooden door with a large brass knob, but when he lands on the floor in the other room the door is now surrounded by a white frame and the knob is visibly smaller.
Continuity mistake: After killing Henriques on the plane, Matrix asks the flight attendant how long the flight to Val Verdes is. When he asks her the question, her hand is on the curtain separating first class from economy, but in the next shot her arm is by her side when she answer's Matrix's question.
Continuity mistake: In the dealership, Cooke never shifts the Cadillac into reverse, and yet instantly starts backing up after he says he likes "the price." The car would have had to be in Park or Neutral in order to be cranked up and would not start in gear.
