- AFI's 100 Years... Series:
- Blooper: At the end of the movie, as Dan is talking to the cops outside, the front door of the house is clearly open. Dan shakes hands with the cop, turns to walk up the walkway. . .cut to inside of the house where Beth is waiting as Dan opens the now closed door.
- Creator Backlash:
- Glenn Close was so angry over plans to reshoot the ending that for two weeks, she refused to do it. To this day, she prefers the original version, feeling that Alex was more suicidal than psychotic. Adrian Lyne wasn't keen on having to redo it either and presumably wouldn't have had test audiences not hated it.
- Close also felt that her portrayal of Alex Forrest perpetuated stigmas against mental illness, particularly the misconception that people with Borderline Personality Disorder are violent towards others.note Ironically, she would later create the organization "Bring Change 2 Mind", which is devoted to de-stigmatizing mental illness.
- The Danza: Ellen Gallagher is played by child actress Ellen Hamilton Latzen.
- Dawson Casting: Alex states her age as 36, but Glenn Close was 40 during filming.
- Enforced Method Acting: Adrian Lyne got Ellen's tearful reaction upon watching her parents argue by bullying the actress and threatening to take away her stuffed animal (that's why she's clutching it). Once the scene was complete, he assured her he was only kidding, and Douglas comforted her with a hug.
- Focus Group Ending: The film originally ended with Alex committing suicide and making it look like Dan (Michael Douglas) murdered her. American test audiences thought this wasn't a good enough punishment for the antagonist, so the ending was changed to Dan killing Alex by drowning her in the tub, but Alex doesn't stay dead at least until Dan's wife shoots her. The original suicide ending has been shown in Japan.
- Mid-Development Genre Shift: Initial scripts were of something more akin to a horror movie.
- Playing Against Type: Up to this point in her career, Glenn Close had played warm, fuzzy, earth-mother women—indeed, she was actually dismissed as a candidate for the role because of this—and been nominated for Oscars three times. This was a radical changeso radical, in fact, that she got stuck playing similar characters for a while.
- Real-Life Relative: Adrian Lyne's daughter Amy Lyne appears as a party guest. Also their first names start with the same letter.
- What Could Have Been:
- The original ending (which is shown in the Japanese version) had Alex commit suicide to make it look like Dan did it and Dan getting arrested for Alex's "murder." Dan's wife then finds Alex's note on tape that reveals the whole thing was a suicide and goes to the police about it.

- John Carpenter and Brian De Palma were offered the chance to direct but both backed out because they feared that the story was too similar to Play Misty for Me. De Palma also felt that Michael Douglas was not a good leading man, but has since admitted he was wrong about Douglas. Carpenter also turned it down because he felt the audience would not accept the originally scripted, downbeat ending. John Boorman was also offered the director's job but turned it down to do his personal wartime childhood memoir Hope and Glory.
