Revealing mistake: When Solina is crawling on the wall, whenever she turns her head, her long hair turns with it, instead of falling freely downward toward the floor. (01:05:20)
Revealing mistake: In the scene where Violet sings for Kevin for the first time, he starts to switch the lights off. Notice when he has turned off the lamps, the room is still very bright, but when he blows the candle out, the room is suddenly totally dark. That single candle could not possibly have lit-up the room and the characters the way it did, after the electrical light was switched off. (00:58:20)
Revealing mistake: At the airport when Jack says 'tow it', there is an extra waiting for his mark to walk outside seen in the reflection of the doors.

Revealing mistake: When Alejandra comes to John's room the first time you see distinct t-shirt marks on John's upper body, his arms as tanned as his neck and face. This in spite of the fact that he wears long-sleeved shirts throughout the movie (except, of course, during his nightly encounters with Alejandra). (00:49:30)

Revealing mistake: During the war flashback there is a newspaper photograph with Captain Junuh on the shoulders of Savannah's young men. When the camera zooms into his face you can see it's someone else's, only in close-up it switches to Matt Damon's.

Revealing mistake: When the priest is running and jumping down the stairs to the subway, he bounces up again, as if he fell on a mat. (00:15:25)
Revealing mistake: In the bowling alley scene where Jeremy and Nick are discussing the red-haired woman, you can see Nick shaking from laughter and even hear it. It is easier to spot if you have watched the outtakes. Nick simply could not contain his laughter during this scene and so they just shot him from behind and left it in. This happens in another scene as well, when they first enter Jeremy's "manly" den. These two were just having too much fun filming this movie. Watch the outtakes.
