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.

Revealing: In the scene where Michael is trying to keep up with Kiefer Sutherland et al along the beach towards Hudson's Bluff, you can see the tyre tracks from the camera vehicle in the sand.

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.

Continuity: About 45 minutes into the movie, when Michael is floating on the ceiling then out the window, he knocks the phone off the hook. The phone then rings and Sam answers.

Continuity: The family dog bites Michael on the left hand in order to "protect" Sam, which leaves a nasty, bloody gash. As Michael runs up the stairs to talk to Sam, he leans the palm of his left hand on the railing a couple of times for balance. There are no bloody hand marks when he picks his hand up.

Continuity: In the scene at the beginning of the movie where the flying vampires are chasing the security guard across the boardwalk parking lot, the positions of his arms as he is running changes back and forth between shots. In the close-ups of the guard's face, his hands are up, holding his hat down on his head. In the wide shots, his arms are down at his side.

Continuity: When the mother is leaving a bottle of wine at Max's house and is being chased by the dog, the dog lunges through the fence. The fence slightly breaks apart by the dog's mouth. The shot changes, and the fence is intact. Another shot and the fences has an even bigger gash in the side, and again, intact.

Continuity: During the opening we see Michael, Sam and their Mom enter the town and check it out. Michael asks a man if there are any jobs in town. The next time we see Michael he's taking his motorbike off the trailer. Then we see him in the car for one shot. When they reach Grampa's house he is riding the bike.
