When the group of kids is running to the cabin after "Lisa" is bitten the character of "Julie", played by Kathleen Rupnik, is missing from the group as they run to the cabin door. Once the cabin door is opened and they cut to the inside shot when they enter the cabin Julie "magically" re-appears among the group. This was first pointed out by Bill Hinzman himself at a private screening at his home in 2003.

The sheriff rounding up the zombies at the end of the movie says "We're going to head west until we meet up with the group coming from the east with Deputy Gary". To meet up with Deputy Gary, they would have to head east if the Gary is coming from the east.

When Harv runs to his car he starts to ring dispatch even though he had plenty of time to start the car and drive away. The plot demands that he stays in the car so that he can be attacked.
