Corrected entry: When Steele shoots the soldier who got bitten in the neck, while trying to collect another zombie, he shoots him in the forehead; the blood splatter appears directly behind his forehead. When the soldier's head kicks back then moves forward, we see that there is no bullet hole in the soldiers forehead. We can also see there is no bullet hole, because Steele's flashlight is shining on the soldier's forehead.
Corrected entry: Towards the end of the movie, just after Rickles is torn apart by the zombies, Steele comes running towards the door that Rhodes locked. He uses his pistol to kill a few zombies, but then he runs out of bullets and puts the gun back in his holster. The slide on his pistol should be back if the chamber is empty, but it appears to be in the normal position.
Corrected entry: When they first make it to the mall, one of the characters is washing her hands in the fountain. In the first shot her left hand is just about clean of blood, but in the underwater shot her hand is bloody.
Corrected entry: In the scene where the zombies enter the bunker the soldiers get scared. Capt. Rhodes is the first one to flee - taking the electro car. next time we see him, there are zombies all around him, he actually hits one with the car. So where do the zombies come from? He must have taken a detour (there is none shown, though) or must have driven that slow, that the slow moving zombies could have overtaken him. Both most improbable.
