Continuity: When Michael first comes home after becoming a vampire he gets some milk out of the refrigerator and when he collapses the whole top of the carton busts open but when his mom comes home and picks it up only one side of the carton is open.

Continuity: Near the middle of the film we see that Michael has a transparent reflection in a mirror because he is a half vampire. Yet, earlier in the film when the other vampires, who are full vampires, are in the video store, their reflections can be clearly seen in a glass counter.

Other: The footage when the vampires are entering the cave. Later when they are exiting the cave, the waves are flowing backwards. The footage has been reversed.
