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.
Audio problem: When Cooke starts up the Cadillac in the dealership you hear the engine turn over and fire twice.
Audio problem: When Arnie sets his stop watch to count down from 11hrs, each second that the watch ticks over there is a loud 'beep'. This is consistent with when he looks at his watch later in the mall, when it reads 9hrs 40mins to go, his watch is still beeping every second. Therefore, Arnie's watch should have been beeping every second of the movie in between these two scenes, but we never hear it. Also, when Arnie and Cindy arrive at the Sunspot Motel (7hrs 57min to go) and when Arnie's in the back of the police wagon, at 5hrs 2min to go, the watch no longer beeps with each passing second.AngryBird
