Eine verhängnisvolle Affäre

Glenn Close still has the knife she used in the movie hanging in her kitchen, stating: "It's beautiful, made of wood and paper. It's a work of art! And it's nice for our guests to see it. It lets them know they can't stay forever."

While Dan is in his attic study listening to a tape, Beth can be seen reflected in the window, waiting just out of shot for her cue.

Barbara Harris is sometimes credited under the name Barbara Iley. In the final credits here, under 'Party Guests,' she is credited under both names.

In the network version shown on TNT in the scene where Alex phones Dan at 2:13 a.m., there is additional dialogue between Dan and Beth after Dan hangs up the phone that is not in the theatrical/DVD version. Beth asks, "Who in the hell was that?" Dan says that it was a client calling and that this happens when you're a lawyer (being called at odd hours). Beth says that it's the middle of the night, still wondering why someone would call at 2:15 a.m. Dan justifies this by saying it's only 11:00 or so in L.A.
