Continuity mistake: When the girlfriend of the lead actor and his cousin are sitting eating pizza in a diner, his hair goes from a little messed up to extremely messed up, then back to a little messed up in different shots. He at no time touches his head.
Deliberate mistake: In the final battle at the end, Mark Loftmore enters the back room where we see Mr. Lincoln leaning over the body of an older man with a red jacket whom Lincoln has apparently just shot. This same man later appears in the background of at least one shot of the general melee taking place outside in the gallery.
Visible crew/equipment: When the General is explaining to the scientist that everyone in the immediate area must be killed to contain the virus, the shadow of a crew member is seen on the wall behind the General.
Continuity mistake: When Bill Pullman is poisoned he has a defined red cross painted on his forehead. He stumbles around for a while and the cross smears to the point where it looks like a big red blob. But when he finally dies and looks at the camera, the cross isn't smeared at all. (01:16:35)
Visible crew/equipment: When a very powerful gust of wind blows Jack out of the castle, a support wire can be seen attached to him.
Other mistake: When Regine becomes the new host of Fright Night, she appears on video monitors and Peter Vincent is watching her on TV while in a bar. Cameras use mirrors, so she shouldn't have appeared on the monitors or on the television at all.
Suggested correction: Most cameras don't use mirrors. Only DSLR/SLR cameras do, which allows you to use a viewfinder. Other cameras, camcorders, and television cameras don't need mirrors.
Continuity mistake: Many editing mistakes with the 'accidents' including the guy at the weight set, when his ribs crack through his skin. In the following shot all is normal again.
Continuity mistake: Clearly a different guy playing Zack in the beginning as he looks to be over six feet tall and has a full head of combed back brown hair. Zack later on looks like he's only 5'5" with receding brown hair.
Visible crew/equipment: When Nicolas Cage returns to his apartment, you can see a crew member reflected in the mirror on the wall right after Cage passes in front of it. (00:11:35)
Revealing mistake: When one character's killed, stomach sliced open, you can see the wire yanking open the prop stomach to the left of the camera.
Other mistake: When translating Dutch for English, one translation uses "their" when it should've been "there." It's in the scene when we first see the lead cop talking to his daughter.
