Continuity mistake: When the windows on Nick's truck are smashed, Elizabeth has protective gloves on when she covers her face from the glass, they are then gone when the truck comes to a halt.
Continuity mistake: After Brenda hears a noise, she puts her book down next to the candle, and walks to the door. When she gets to the door, the book is now by the opposite side of the candle. (00:52:50)
Continuity mistake: The amount of blood on Kate's face decreases between the time she is attacked and discovered. The pattern changes from shot to shot as well. (00:34:15)
Continuity mistake: Kim is at the kitchen table with her brother Alex. Kim has a necklace on. Kim asks Alex about having a date for the prom and all that is around her neck is a gold chain. The shot then cuts to Alex and then back to Kim and now there is a gold star hanging from her necklace.
Continuity mistake: At the beginning of a bedroom scene, Elizabeth Taylor breaks a mirror. Later on in the same scene, she sits down at her dressing table, and the mirror is back in place and unbroken.
Continuity mistake: In the last scene, the Butler and Groomsman load a Sarcophagus in the back of their station wagon. The tail gate is left open and both step back as the vehicle pulls out. As they are driving off down the driveway the tail gate is closed.
Continuity mistake: When Mrs. Morgan notices the peppermints, they're individually wrapped. When she picks one out, they're unwrapped.
Continuity mistake: The roof of the Chessman House changes, going from having a middle roof to no roof in the middle.
Suggested correction: You can't see the full roof in the second image because it's a low-angle shot looking up. But if you look closely, you can indeed see a little bit peeking out, and even see the tips of the two attic windows. Furthermore, it was a house exterior they built specifically for the film... what purpose would there be for removing the roof for this one random shot?
Continuity mistake: In the very last scene, Hoskins opens the back left hand passenger door. He gets in, and is seated right on the edge of the seat (as far left as he can go) when the car takes off, and Brosnan pops up and aims a gun at Hoskins. Hoskins does not move. However, from the camera angle, Brosnan is pointing a gun at the middle of the row of seats, whereas Hoskins is sitting on the far left.
