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: 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: 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: When Dan and Alex are under the rain, a black man in a gabardine passes by Dan, and a frame later passes by Alex, in the opposite direction.
Continuity mistake: Dan is having a drink with Alex and he talks about his parents' divorce. His glass swaps from being on the table to in his hand between shots.
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: 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: When Glenn Close calls Michael Douglas in the middle of the night, his clock radio reads 2:13. In the next shot, without him touching it, the clock is dimmer and has been moved so we can't see the new time. Then about a minute later, the clock radio reads 2:20.
Continuity mistake: Dan throws his umbrella and it bounces on the edge of the wastebasket but lands on the floor. When he walks next to the wastebasket the umbrella is now inside.
Suggested correction: It lands on the ground and stays there.
