Continuity mistake: When Ben has dispatched the first Zombie out of the door and turns to Barbara, there is blood on his shirt near the shoulder. Yet when he takes off his jacket the shirt is clean, only for the blood to reappear again when he is walking towards the windows. (00:13:50)
Continuity mistake: When Cooper is saying its a good idea, you can see a beer can on the piano and Cooper is holding a baseball bat in his right hand. When Barbara says look outside, the next shot Cooper is holding the beer can in his right hand, and the baseball bat in the other. (00:33:55)
Continuity mistake: After the sequence where Ben tells Barbara she is losing it and then comforts Judy Rose, we see Barbara reloading a shotgun and Ben in the background nailing a white door in the next room. After it cuts to a shot of Judy and Tom nailing another door, we see Ben knock over a table while holding and putting in place the same door he had previously been nailing the window shut with. (00:53:30)
Continuity mistake: When Cooper goes upstairs to get the TV set, in the room, the power cord hangs a little bit. Next shot, in the hallway, the same cord is on the TV set, not hanging at all. And in the next shot, when going down the stair, he holds the cord in his hand. (00:57:00)
