Revealing mistake: The female zombie grabs onto the back of the car and is dragged through the mall. Stephen shoots the zombie in the eye and if you look closely you can easily see this is no longer the woman from before, but actually a man who doesn't resemble her at all.
Revealing mistake: In one of the river flooding scenes after the dam bursts, you can see a modern day vehicle (most likely a pickup truck) for a few seconds on a highway next to the river. (01:50:30)
Revealing mistake: In the opening shot, as Jennifer gets into her car, people on the street, stop, stare and even point at the camera.

Revealing mistake: When the neo-nazis burst into Kohler's apartment, they stab him and he slides down with his back against the wall. While Mengele picks up the phone, you can see the 'dead' Kohler blink in the background.
Revealing mistake: After the trailer explodes on the bridge, towards the end the truck swerves to the left. As it drives off the bridge there is no tail shaft between the gearbox and front diff - the truck falling off the bridge is just a shell.

Revealing mistake: Watch carefully during the fight scene between Billy and Rifki, you can see the stuntmen a few times.
Revealing mistake: During the sax player's solo (final concert), his fingers don't match the notes, and he stops moving his fingers before the solo is over. Also, the sax player in the blue jacket behind Buddy's right side often lags behind the sax player to his right. At times, it looked like the sax player was watching the sax player next to him to know when to play. Sometimes, he would put the reed in his mouth for a fraction of a section and just pretend to be playing. Near the end, both sax players seem lost and even laughing at themselves. (01:47:17)
