Continuity mistake: In the very first scene we see Ann Archer pulling down a shade from afar with the curtains pulled to the side. Then we switch to her inside the apartment and see the curtains are already closed. (00:02:00)
Continuity mistake: Quincy is sleeping on the little girl and keeps changing positions on her lap. (00:02:10)
Continuity mistake: As a little girl is sitting on the couch with the dog, there is a book to the left of her which is gone in the next shot. (00:02:35)
Continuity mistake: In the party scene the people behind Stewart Pankin on the slow moving food line change it just a matter of seconds from shot to shot. (00:04:50)
Continuity mistake: The part in Stuart Pankin's hair keeps changing in the party scene. (00:05:40)
Continuity mistake: In the elevator scene as you look down the shaft from above, the air is crystal clear with no smoke in sight. Then in a few seconds smoke appears near the windows but in the next shot when the elevator stops the smoke is gone. (00:20:10)
Continuity mistake: In the scene where Michael Douglas is listening to the answering machine look at the towel to the right of the paper towel rack. It is moved the next time you see it. (00:22:15 - 00:23:05)
Continuity mistake: As Michael Douglas listens to the answering machine, the green overhead lamp that is above the table in the beginning of the movie is gone. (00:22:20)
Continuity mistake: When Michael Douglas comes home the first night after being a bad boy with Glenn Close, he is shown in the kitchen talking on the phone to his wife at a little after 8:30 AM. Not only does he talk to her, but he also has a whispery chat with his lover, walks all about the kitchen, sits at the table, and the time on the clock doesn't change once. (00:22:20 - 00:23:05)
Continuity mistake: When Michael Douglas pretends to be hurt in the field, Glenn Close says, "My father died of heart attack," and she has a long earring dangling from her right ear. In the very next shot it's gone. (00:27:05)
Suggested correction: The earring is still there.
Continuity mistake: After Glen Close kicks Michael Douglas out of her apartment he's standing next to her bicycle holding his stuff. It can be assumed that he put the stuff on the bicycle seat because in the next shot his hands and the handlebars are empty. But later as we see him getting ready to leave again his stuff is the on handlebars. (00:34:35 - 00:37:10)
Continuity mistake: As Michael Douglas busts down Glenn Close's door, you to see from the outside it's not latched. But from the inside it is. (00:41:25)
Continuity mistake: The amount of wine in the Michael Douglas' glass changes in the scene where he is talking to his daughter about rabbits. It fills up without being touched. (00:41:30)
Continuity mistake: When Michael Douglas is listening to Alex's tape it's midday when he enters the East River Drive underpass and comes out the sun has clearly set. Alex's tape doesn't skip a beat. (01:17:00)
Continuity mistake: When the little girl is playing in the back yard outside the rabbit cage it's winter, not a leaf in the tree she is under. In the very next shot as they get into their car all shrubs and trees in this shot have their leaves. (01:23:10)
Continuity mistake: The little girl appears to have been given a haircut after we see her at the empty rabbit cage, most apparent when we see her the following morning. (01:27:00 - 01:30:30)
Continuity mistake: Playland, Rye NY in the spring, summer and autumn. Alex and the girl walking to the Dragon Coaster. It's spring with the leaves in bloom. Then in stock footage of a different roller coaster being pulled to the top, it's fall with the leaves a golden yellow. Then in other stock footage, the trees are a lush summery green. (01:36:35)
Continuity mistake: In the famous bathtub scenes there's a close-up of Alex's feet with blood dripping on her right foot. Later when we see her in the tub the blood is in a different spot on her foot. (01:51:40 - 01:53:15)
Continuity mistake: There is a lot less blood on the knife after Glenn Close flings it than there was in the shot before when you see her fall. (01:51:50)
Continuity mistake: The water level was almost but not quite overflowing the brim of the tub when Michael Douglas is pushed in, and the faucet was still running, so there should have been more water on the floor. (01:52:25)
