Other: When the zombies come out of the river and start marching, look closely. The first zombies to come out wear wet clothes, but the ones in the back are dry. Submitted by Grigory the Wanderer

Continuity: When Kaufman sees Big Daddy, he shoots at him, particularly in his right shoulder. When Big Daddy turns to look at Riley at the end, the bullet holes are gone.

Continuity: When the bikers ride through the zombie infested town for the first time watch when Big Daddy is shot at. The windows behind him are shattered by the bullets but a few seconds later are fully intact. This may be hard to see as it is dark but they are back, easiest way to tell is by the reflection from across the street. (Time)

Visible crew/equipment: When Dead Reckoning (the massive truck) is starting to be surrounded by zombies there is an extra spotlight mounted on top of it. It wasn't there in any of the earlier scenes. The shot where it's visible has Dead Reckoning on the right, eight or nine zombies on the left all walking by, and a few powerlines visible in the background. It looks like they just put it on top to give some extra light on the zombies.

Revealing: At the beginning of the movie, when the guy is bitten in the wrist, if you watch and listen closely when he shoots himself, the blood comes out of his head before he actually shoots.
