Plot hole: When Charlie sets out to hijack the money train, he jumps off the platform onto the tracks as it arrives, in plain sight of the driver and other passengers at the station, and only puts his mask on once he's in position on the tracks. The train conveniently stops right over top of Charlie, allowing him to enter through the conveniently-placed grate on the train's floor. (01:17:15)
Continuity mistake: When they are arguing in his bedroom, her scarf and coat are closed at one point, then open, then closed.
Factual error: When Lovell's daughter is complaining that the Beatles have broken up, she slams the album Let It Be into her rack. The scene takes place on the day of the initial explosion aboard Apollo 13, April 13 1970 - immediately prior to the Lovell family attending the screening of a television broadcast from the spacecraft. Let It Be was not released as an album until May 9th, 1970. In April Ringo was still recording drum tracks, not even possible for an advance copy to get out.
Other mistake: The Magic Eye Picture that Willem is looking at throughout the movie is NOT a sailboat. If you pause the movie and find the image it's actually three rows of 3D shapes.
Continuity mistake: In the scene where one of the "high council" is speaking (behind a desk or pedastal), there is a close-up shot of the highest ranking council member's face. In his nostril you can see a dry booger. They then change the shot and then come back to a close-up of his face. The booger is no longer there. Sorry if this is a bit gross, but I found it amusing.
Plot hole: It seems that an awful lot of time and effort was taken in planning this caper, what with all the bombs planted throughout the arena and all, but the terrorist were pulling this during game 7 of the Stanley Cup Finals. What if the series ended at game six in Chicago?
Continuity mistake: At the beginning, Nix threatens young Dorthea with a real madrill, but that's all we see of it. It's never shown being put away, and it's not there when Swann and his crew break in to incapacitate Nix.
Visible crew/equipment: During the fight between the Rippers and the guards at Water and Power, you can see the stunt wire attached to one of the Rippers.
Visible crew/equipment: During the battle against the dinosaur skeleton, you can see a SFX guy in one shot as the creature whips its head around. He is on the left edge of the screen, standing partially in the frame and visible for nearly a full second.
Continuity mistake: When Gloria is confronting her "baby's daddy", her earrings keep disappearing and reappearing.
Continuity mistake: In the final scene in which a man is shot in the airport (part of this scene actually recurs throughout the movie), the psychiatrist woman leans over him to hold him as he dies. From one angle, he reaches up to her face and his hand is clean. In the next angle, his hand is covered in blood as he touches her face.
Factual error: When the porter first gets ready to shoot at the terrorists (after Ryback falls off the train) he goes through a series of verbal instructions to remind himself what to do. The very first thing he says is "safety off". The problem is that the gun he is using is a Glock pistol. Glocks use a device called a "safe-action trigger" but they don't have a manual safety that you turn on and off.
Visible crew/equipment: When Neil (De Niro) breaks into Van Zant's apartment and shoots him, watch as Van Zandt flies backward. You can see a wire running up through the bottom of his sweat pants.
Continuity mistake: When the soccer coach is talking to the team in the class room she pulls down the world map on the screen. The camera flips back to the team for about 2 seconds and when the camera turns back to the coach the screen is pulled up
Continuity mistake: When the Aunt flags down the cop car, the cop has his seat belt on, as the plant starts coming in the car to grab him and the car. He jumps out of the car without ever undoing his seat belt. (01:14:45)
