Continuity mistake: In the middle of the hotel fight when Toby and Deliverance go through the door in their hotel room you see the door open and a number of shots impact it. The characters then go through the second of the double doors. This is commented on in the DVD commentary. Not only do the bullets not go through the second door, they don't go through the first. On top of that, you see a shot with the two doors opened, but when the bad guys enter the room the double doors miraculously turn into just one! This layout is then used for the rest of the scene.
Visible crew/equipment: When Brad Pitt is taken prisoner by the English, he tries to escape and is thrown in prison. As the camera turns back to the door, the shadow of a microphone is visible left to the door.
Factual error: Secretary of State John Hay is depicted issuing the order to "initiate hostilities" against Spain. Unfortunately, at the time we actually went to war with Spain, John Hay was not the Secretary of State. That position was held by William. R. Day. Hay did not become SofS until September of 1898, after most hostilities had ended.

Continuity mistake: At one point near the beginning when they're collecting the crew, Robert Carlyle is in the car smoking. He lifts the cigarette to his face and he's not wearing a glove. In the next shot he smokes again and he's wearing gloves.
Continuity mistake: When Joe and Gus enter the diner towards the start of the film we see the waitress come over to see if they are ready to order. The camera switches from looking at Gus and then to Joe. When the camera is on Joe, we see the guy sitting with his back to Joe turns his head round to the left to look at Joe and Gus. Then when the camera changes angle to look at Gus and Joe from in front of this guy, his head is twisting back round from the other direction (right to left).
Continuity mistake: In the scene where Dunn is collecting gear from the surplus store. The cops show up. When it shows a close-up of the cops in front of the cruiser the wipers are on, but then it goes to a distant shot and they're not on.
Revealing mistake: When Georgie stands up at the roof-top pond, she casts a shadow on the background sunrise.
Continuity mistake: When Richard Gere's attorney tries to get into the murder scene apartment, the guard says to her (in subtitles) "if you mess up the murder scence [sic] you will be in some trouble". There is a typo in the subtitles.

Continuity mistake: In the final scene, when Parker Posey shoots her brother, just before they act out their JFK shooting re-enactment her shirt is unbuttoned and she begins to button it. A couple of minutes later, when she's holding the gun, her shirt is unbuttoned again.
Continuity mistake: In the last scene, Max's bathing suit changes color, from dark blue to light tan, back to dark blue.
Revealing mistake: In the scene where the geoligist's husband calls her from the L.A. airport to say he's going to try to make it home, a strong aftershock collapses the wall that the pay phone is mounted on - as this occurs you can see cables attached to the wall pulling it over.
Audio problem: When the child is being tested for what objects he picks up, he handles one of the bells by holding the clapper, yet still the bell chimes.
Plot hole: Katherine (Kirstie Alley) the tooth fairy is instructed by Rodgers (Lynn Redgrave) that she can only go out at night, otherwise she stays in an apartment in Limbo to get her assignments. She is given names all over the world. There is always a part of the world that is in nighttime. She should always be working and never at Limbo.
Continuity mistake: In the scene where the postman gallops by the country house full blast and then comes back to pick up the letter from the boy's hand, you hear hoof sounds for long enough to take him hundreds of metres away, while the camera is on the boy. But when he is actually shown stopping to turn his horse around he has only come as far as the corner of the premises, maybe 20 meters away. (01:53:05 - 01:54:05)
Continuity mistake: After the explosion in the laboratory, Josh is laying on the floor, injured. His face is covered in blood, however during the scene the amount of blood on his face keeps changing. In close ups of his face his lips are free of blood, but in wider shots his lips are covered in thick amounts of blood.
Continuity mistake: Robert Downey Jr.'s two girl friends sit down at the kitchen counter of one's loft to share a bottle of tequila and their sorrows. The camera shifts back and forth between the two as they dialogue and the cap to the tequila bottle sitting on the counter disappears and reappears between shots.
Continuity mistake: In the end when the Kothoga is on fire and chasing Margo, it catches up to her in moments. However, everytime it dramatically changes angles, the Kothoga appears a lot futher away than it was previously, but soon after catching up once again. Noting her progress in the room, this situation is not simply replaying the same scene from different angles. Plus when she gets to the water tank, she has plenty of time to spare to hit a lever, climb the device, and jump in before the Kothoga looms overhead.
