The Hand that Rocks the Cradle (1992) - 8 mistakes

Continuity: After Claire punches Peyton for the first time, there is blood on Peyton's face. When she gets up off the floor, the blood is completely gone.

Continuity: The baby's burping pad disappears and reappears from Claire's shoulder after Peyton pretends to save the baby from choking on the earring.

Audio problem: When Claire is in the car about to leave hospital, she turns around to tell Emma to put her seat-belt on. Though you hear her say "fasten your seat-belt sweetheart" - her lips aren't moving when you hear "sweetheart".

Continuity: There is a scene where Marlene is frantically driving. They show her from the side without a cigarette and without any cigarette in either of her hands. then they show out the front windshield so that you can just see her empty hands holding the steering wheel. When they cut back to her a face she has a miracle cigarette in her mouth.

Plot hole: It's extremely unlikely that through the proceedings, before Dr. Mott kills himself, that the family would never have seen his wife, especially with all the news coverage of the story.

Continuity: When Emma takes the baby to hide in the closet, you hear him frantically screaming. As they show his face, he is just looking around calmly.

Other: When Peyton and Emma are watching a scary movie in Peyton's room, Emma is eating popcorn. However, if you watch her mouth, she isn't actually eating anything (just doing an incredibly bad job of pretending to).

Audio problem: When Claire and Marleen return from lunch and both are greeting baby Joe, you can hear him screaming his head off. However, when Claire hands him back to Peyton, you see his face and he is not distressed at all (even though you can still hear the crying).
