Corrected entry: In the scene where Ben gets the lever action rifle from the corpse, he cocks the lever expelling a used round and supposedly loading one more in the chamber. However when he runs down after hearing the screams he cocks the rifle again and no round is released. Meaning the gun is empty but in later scenes it fires without anyone reloading it.
Corrected entry: I don't see how Ben turned into a zombie. When the guys got to the house, they had to cut open the door meaning that zombie's didn't get through it and Ben was never bitten.
Corrected entry: After the truck explosion in which Tom and Judy were killed, Helen fights her husband forcing her into the basement, loudly exclaiming that she wants to wait for Ben to get back. However, if Ben hadn't fallen off the truck, he would have been there when it exploded. There was no way for Helen to know that Ben hadn't been killed.
Corrected entry: Towards the end of the film (after the zombies raid the house) Ben sits alone in the basement. When he turns on the radio, the date is given; late August, 1989. However, just look at the clothing in this film, everyone is wearing suits, long clothes. Tom is even wearing a jacket. In fact, when Ben goes out to kill the zombie he hit with his truck, his breath is visible, indicating it is quite cold outside.
