Continuity mistake: One scene has Glenn Close in bed shot from profile, and the sheet in down exposing her breasts. The film cuts to a frontal shot and the sheet is up around her neck. When it cuts back to profile, the sheet is down again.
Other mistake: Dan and Alex go to what looks to be Alex's apartment after meeting at the office and going for a drink. After romping around in bed, they go dancing, and on the way back through the meat-packing district, she leads him to the door of her apartment and tells him she lives upstairs and he says something like, "this is your building?" It seems odd as they were just up there having sex.
Visible crew/equipment: When Michael Douglas goes to the police for the first time, after he gets the tape, when he is talking to the policeman watch for the reflection of the boom mike to the right of the cop's head in the trophy plate. It's beautiful and in every shot. (01:22:40)
Continuity mistake: In the beginning, Michael Douglas tells Glenn Close that he has a 6 year old daughter. Later in the movie when Douglas is talking to his wife on the phone about the daughter missing school, she says "She's 5 years old, what is she gonna miss, Trigonometry?"
Visible crew/equipment: The boom mic is visible in the top corner of the Volvo's windshield, when Michael Douglas waves goodbye to his daughter on the street at the beginning.
Continuity mistake: While in his first meal with Alex, Dan's collar swaps from being outside to inside his jacket.
Other mistake: After Dan visits his wife in the hospital, he goes to Alex's apartment. In the scene where he's chasing Alex and crashes into the glass door, shattering it, look closely at his face and you'll see it's not Michael Douglas but a stunt double. A few seconds later when they are struggling in the kitchen, look again and you'll see the same stunt double.
Visible crew/equipment: While Michael Douglas is listening to the tape in the attic there is a reflection in the window of someone who looks to have long blonde hair, just above and slightly to the right of the lamp. (01:20:40)
Revealing mistake: As Glenn Close is being choked, Michael Douglas is holding her throat very loosely. (01:42:20)
Continuity mistake: When Michael Douglas puts on Glenn Close's tape in the rental car, the radio is set at 97.1. When he removes the tape, it's at 107.9.
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: While Dan [Michael Douglas] is listening to the Alex's [Glenn Close] tape in his car, Alex is following him in her car. They both have to drive through a toll gate and slow down so as to throw coins for the toll fee into a funnel. Observe Alex: As she is about to throw the coins, we see her in close up using her RIGHT hand. In the long shot, we see her LEFT hand depositing the payment.
Continuity mistake: At the end of the film during the final confrontation when Michael Douglas first forces Glenn Close into the bath tub only her ankles are over the edge of the tub, however in the very next shot her knees are dangling over the edge. (01:52:40)
Continuity mistake: In the last portion of the film, the background shows autumn-leafed trees when Anne Archer drives downtown. When the scene switches to the house, all the trees are lush and green in the yard.
Audio problem: The dialogue that Michael Douglas hears Glenn Close saying when he walks into his apartment to find Glenn Close talking to his wife is the exact same thing that she says just before she leaves when Ann Archer gives her their phone number.
Revealing mistake: In the final confrontation scene Glenn Close comes out of the bath tub and raises her arm, the scene cuts to the gun and when it returns to Glenn Close you can see the fabric of her dress has changed to a thicker one to accommodate and cover the squib needed for her gunshot wound. (01:54:05)
Revealing mistake: When Michael Douglas is listening to the "deposition" in his study, look closely at the background window. You can see Anne Archer's reflection in the glass, together with someone else (probably crew), just waiting for her cue to come in and surprise her husband.
Continuity mistake: Iron Couple Award: Not necessarily a mistake, but Michael Douglas and Glenn Close start their frenzied lovemaking in the kitchen as a clock reads 4:45, and they're still going at it when the clock later reads 6:15.
Suggested correction: You're right, it isn't a mistake and shouldn't be listed as one. Some people can have sex for hours, you know.
Continuity mistake: There is a scene near the beginning shortly after Michael Douglas and Glenn Close meet. They go to a restaurant and get caught in a rain shower on the way. When they sit down, Michael Douglas is soaking wet. The shot changes from Michael to Glenn and then back to Michael - suddenly he is bone dry. Then the camera goes back to Glenn and then back to Michael and he's soaking wet again.
Continuity mistake: Glenn Close changes her dress from the shot where she gets up out of the tub to the next shot where she is shot. The bloodstains on the collar are different. (01:54:10)
