(00:02:50)
Continuity mistake: The little Nono is singing the nursery rhyme in front of the cafè. One of the nazis tosses him a coin, while the other puts the cigarette down, but at the cut he's already taking a puff.
Continuity mistake: After the shootout at Sarah's birthday party, White Mike is visited at the hospital by Molly. Mike's pillow has marking "Property of Queens Hospital", they cut to Molly, then back to Mike, and the marking is gone. Regardless, they were in Manhattan, they would not have taken him to Queens Hospital anyway.
Continuity mistake: When Charlie is coaching Sam in baseball at the beginning of the movie, they get on the road and he beckons to him. In the first cut, people in the background change (most obviously, a guy is crossing the street behind him, but vanishes in the second shot). (00:07:45)

Continuity mistake: In the classroom, Jarod leaves with Detective Fairchild's business card in his right hand and accidentally (maybe deliberately) left the "Death and Cremation" book on the floor. Courtney picks up Jarod's book, apparently with the intent to give it to him the next time she saw him. Later, Courtney is reading the book and finds Detective Fairchild's business card between pages (like a bookmark). If this was meant to be the one the detective gave to Jarod, it can't be. (00:50:41 - 01:01:05)
Continuity mistake: In the beginning, when Billy is talking to the bum (who later turns out to be Tawny), the bum has a glove on his right hand. When he reaches his right hand out to Billy and Billy gives him a subway token, there is no glove. It's back in the next shot.
Continuity mistake: Throughout the motorcycle/police car chase they used two different motorcycles made 50+ years apart and just painted them both black. One is a 1940s Harley Davidson with a springer front end and the very recognizable horn below the headlight, and the other is a late 1990s (at the oldest) cruiser with a front end that's completely different in every way.
Continuity mistake: The silver SUV in which John, Laura and their son are escaping, changes several times from one to two inspection decals on its windshield. Firstly there are two decals reading 9_10. Right after Laura tries to step out of the running car and they almost collide with a truck, the SUV comes to a full stop and there is a single decal reading 5_10. When they are at the checkpoint leaving Pennsylvania we go again to two decals. Additionally, when two decals are present, they sometimes read 9_10 and some other times 11_10. (01:38:00 - 01:43:20)
