Revealing mistake: During the car chase scene, if you watch the speedometer on the car, it never rises above zero. That and the obviously poor image quality of the "road" in front of them shows that they were using projected film in front of the car.
Revealing mistake: When the new Pope is announced, the New York Times headline is shown, and 'Copyright 1990 The New York Times' is visible. The event took place in 1979.
Visible crew/equipment: When Officer Romero and Arthur are alone in the house, handcuffed to the brass shelving unit, as she says, "Help me or I will crush you like a damn bug," a crewmember wearing glasses and a blue shirt is seen crouching on the floor, at the bottom right of the screen. (00:53:05)
Revealing mistake: In the disco scene, the DJ is playing music, but the Pioneer decks and the DJ Mixer are not even turned on, as no lights are showing.
Other mistake: When Iron Man and Iron Monger are fighting, Iron Man catches the SUV, and you can see the family inside the car. Although the car is completely vertical, the hair of the people in the car seems to defy gravity.
Plot hole: Prior to the final show, when the horsemen are performing separately at different locations in London. [Scene X] Jack is busy with his card swap trick. While others are doing their tricks too, [Scene Y] McKinney is believed to be tricked once again by his face sharing brother at another location... Dylan gets a call and then he calls everyone to wrap up and meet somewhere. [Scene Z] Jack also wraps up and leaves the place... OK. Later after the expose in final show McKinney tells the story about how Jack successfully hypnotized his brother [in the Scene Y]. How could Jack be at two different locations at the same time? He was performing somewhere else when he did hypnotism at another location and then wraps up his trick back where he started.
Continuity mistake: While breaking down the bathroom door with the axe, Jack repeatedly strikes and damages the right hand panel, but as he turns away from the door (when he hears the snow-cat) both left and right panels have been damaged.
Continuity mistake: When Bella and Edward talk in the woods, Bella drops her backpack in front of a tree. In a subsequent shot, the backpack has disappeared. (00:49:55 - 00:50:55)
Continuity mistake: Terence Stamp takes out a pursuing vehicle by reversing his own car into it at high speed and pushing it over a cliff. When he subsequently drives off, amazingly there's no damage at all to the rear of his car. Shortly before, it is peppered with gunshot holes which mysteriously disappear.
Continuity mistake: When Mulder and Scully start frantically running from the bees inside the dome Scully is clearly seen untying her belt twice. (01:01:55)
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. (00:31:00)
Continuity mistake: In the beginning of the movie when the Angels are rescuing the US Marshall, Lucy Liu is wearing stiletto heeled boots. When they jump out of the window, the heels are square. (00:01:30 - 00:06:40)
Other mistake: During the scene where the Japanese are being rounded up and taken to the internment camp, the camera is panning over the crowds of people walking down the street. Half way through this scene, there is a woman and a little girl, who seems to be carrying a stuffed Elmo, hardly appropriate for the time period.
Continuity mistake: At the end of the film before Nicolas Cage jumps in the ocean, the sky is overcast. Once he is in the ocean, the sky is clear blue.
Continuity mistake: When Bond escapes from the Willard Whyte facility in the desert in the moon buggy, a car that is chasing him goes over a ridge and turns on its side as the buggy speeds by. A wheel rolls back into the shot, all on its own. It doesn't belong to the car, or the three three wheelers also chasing, but looks like it belongs to the buggy, which has its full compliment of wheels all through the scene.
Plot hole: The whole concept of a kidnapper 'pretending' his victim didn't get on the plane in the first place is utterly laughable. Even if nobody saw her in her seat, why didn't they see her walking down the aisle to her seat, or waiting to board the plane, or in the boarding tunnel itself? Why isn't she listed on the passenger manifest, or on her mother's travel documents or airline ticket? And there would have been security cameras all over the airport.
Continuity mistake: When Felix looks out at the Anfield pitch you can see executive boxes on the opposite stand. He is meant to be in an executive box but can't be, as only one stand at Anfield has boxes. (01:16:20)
Other mistake: The construction of a staircase does not require a large nail at the site shown on the steps. Furthermore when Emily snags her clothes basket on the stairs it lifts a small nail up. How did it grow into a 2 inch fat nail?
Factual error: The plastic explosive used on the cockpit door was C-4. When shot (as shown), C-4 does not explode; it requires the use of a detonator.
Suggested correction: You can see him applying a detonator prior to him shooting it.
Continuity mistake: When Carter and Zhang Ziyi are fighting, Carter is wearing alligator skin shoes (brown). However, when Ziyi thrusts the sword at Carter and Carter falls back on a chair raising his feet, you see him wearing black running shoes with a white sole.
