Continuity mistake: The ruler in Tess' hands instantly changes design. It looks like she flipped it over between shots, but without any time or reason to do so. (00:19:20)
Continuity mistake: The 3 girls lock Sadie Shelton in a closet and then bring a chair to secure the door and Rose sits. A couple of seconds later, Rose is standing again holding the door. (01:28:05)
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)
Continuity mistake: Throughout the film Elvira wears her trademark black dress, split to the top of her thigh, and underneath it she always wears black pantyhose. Inexplicably, this changes to black stockings and suspenders when she is undressing for bed on her first night in her new house. (00:31:35)
Continuity mistake: In the scene where Bill's old boss comes back to see him notice when Bill shoots him and takes the drink. All of the drink comes out of his chest because of the bullet holes. Well notice his shirt is all wet, then in the next scene when he takes off his hat his chest is all dry.
Continuity mistake: When Harrison Ford is on the rooftop and the suitcase accidentally opens, the Statue of Liberty goes flying off the rooftop and on to the ground, several stories down. In the next shot, the little statue is perched at the edge of the rooftop. Also, the clothes that fly away magically reappear next to the suitcase a shot later.
Revealing mistake: During the fight montage, the winner of the first match wins by kicking his opponent in the face. His foot never makes contact.
Visible crew/equipment: After Ken kills the last dog and the witness has a heart attack, he walks out of the house he was in and in the reflection of the black door you can see a crew member and a camera. (01:19:35)
Revealing mistake: During the big fight scene, you can tell easily that Frank is wearing knee pads (try looking when his pant leg is wet). Construction workers will often wear knee pads for work but most often they wear them on the outside of the pants to save the knees of their pants. (00:58:50)
Deliberate mistake: When Barry is on the phone with Kent for the 2nd time (right before Barry invites Kent to the station), we see Dan (Alec Baldwin) in the booth trying to get Barry to hang up on Kent. Dan holds up a sign that says "dump HIM." Problem is, we are looking at a reflection of the sign, so the sign was actually written backwards, as a mirror image.
Continuity mistake: Arnie enters the parking lot driving on two wheels crying "Woooa." The close shots show him with one hand on the wheel and the other outside on the window; but on the wide shots, with the stunt, both hands are inside and his mouth closed but still the cry is heard. This mistake goes on every time angle changes.
