Visible crew/equipment: When Marcus attacks Simon at the loading dock, as Simon flies through the air after Marcus kicks him, you can see the face of Johnny Lee Miller's stunt double. (00:57:15)
Continuity mistake: After the ball game, there is a cut over Miguel's eyebrow. Right after this scene, the cut has disappeared.

Revealing mistake: Brad Pitt's tattoos appear to smudge during the last fight.
Other mistake: When Chester is taking Jacko's pipe, Nelson gets up out of his seat. When they show Jacko really really mad, you can look in the background and Nelson is sitting down. When they show him again he is out of his seat.
Continuity mistake: In the scene where they are in the all you can eat restaurant, when PaPa Klump farts into the candle causing the curtain to catch fire, when they first show the curtain after the 2 men put out the fire, there is clearly a burn mark on the edge of the curtain. However, when they show the curtain again, there is no burn mark. (00:17:25)
Continuity mistake: When Elliot's the basketball player, when he scores the slam-dunk and breaks the headboard, he breaks the headboard after the slam as he bounces/hangs off the headboard. But in the replay he breaks the headboard as he makes the slam and then bounces/hangs off the headboard. (00:49:10)
Continuity mistake: Ben Affleck has a large tattoo on his right shoulder/bicep that has been covered up by make-up for the movie. During the 'waterpark' scene Ben is wearing a T-shirt and when he scoops the little boy out of the water and lifts him into the air the sleeve of his shirt pulls back a little and you can clearly see the bottom of his armband tattoo.
Continuity mistake: The 3 main characters are having dinner with Anne Bancroft. You can see Jenna Elfman's dark roots. After she and Ben Stiller go home the roots are light. Did she stop to get her hair touched-up on the way home?
Continuity mistake: In one scene where the dad is leaving for work, he sees a dog and in that shot you see his mail truck and the door is open. Then you go to a close-up of the dog and when he runs to his mail truck the door is now shut.
Character mistake: At the memorial service the principal says that it's been 39 days since 39 loved ones had died. But there were 40 students on the plane and 4 chaperones, making the total 44. Now 7 people got off the plane, which means 37 people related to that memorial service actually died, not 39. Two pilots would make up the numbers, but there would be flight crew too, which still leaves the numbers off.
Factual error: In the scene at Lord Cornwallis' outdoor party celebration, right after Benjamin Martin and his Continental Army blows up a British Ship, one of Lord Cornwallis' Captains throws back a big gulp of his drink from his Martini glass in grief and disbelief - the problem is this movie takes place in the mid 1700s and the Martini Glass wasn't invented until the 1920s, during the Roaring Jazz days.
Continuity mistake: After mowing down all the Immortals during the Sanctuary scene, one Watcher tells another to take their heads because they might be Immortals. You see the Watcher to the left side of the screen and a robed figure to his left about four feet away drawing his sword. Suddenly, that same robed figure is now to the Watcher right side and about two feet away.
Continuity mistake: When Trip passes out at Wordfest, and he wakes up with Sarah standing over him, watch her hands. Every time they switch shots, her hands switch back and forth between holding a cigarette and a box of cigarettes, to her simply having her hands at her sides. (00:28:35)
Factual error: When John Cusack puts Springsteen on his LP-player, he places the needle at the start of the record. The song that plays is the studio version of "The River." Therefore, the album has to be "The River," which is a double album, but "The River" is not at the start of either of the two LPs, but is the last song on LP #1. (00:18:10)
Continuity mistake: After Spike chases Jean-Claude out of the church, the parents and their kids stand outside. Chuckie is in his father's arms holding his Wa-wa (teddy bear). They go back inside, where Kira gives Chuckie that same missing teddy bear.

Visible crew/equipment: When the police are leaving the motel, you can see a camera reflection in the S.W.A.T. van as it drives by. (01:18:10)
Other mistake: In the scene with the last match between DDP and Jimmy King, when Jimmy King is on top of the cage and grabs the belt, he is holding it up. It shows the belt has a nameplate on it saying Jimmy King. If DDP was the champ, wouldn't the nameplate read DDP, or Diamond Dallas Page?
Continuity mistake: As Gal is in front of his pool, standing with his back to the rock face, an immense boulder is tumbling straight towards him. It comes down the mountain to his right. As it gets airborne it is still to his right. Camera cuts facing his right and it is shooting past his right side, still moving straight downward. All good. But as the camera cuts to the front of Gal, the boulder smashes into the pool a couple yards to the left side of Gal. (00:04:50)
