- The Cast Showoff: Michael Douglas (a former race-car driver) did most of his own stunt driving in the film.
- Dawson Casting: Nick was described in the script as being 42. Michael Douglas was 47.
- Deleted Scene: Subverted. The sex scene between Nick and Catherine was shot over five days so that it could be edited rather than cutting it completely should the MPAA object to its explicitness, which they inevitably did.
- Enforced Method Acting: During an interview with RuPaul and Michelle Visage, Cassandra Peterson reported that during the scene Bill Cable is stabbed with the ice pick, the ice pick was only supposed to hit the blood packs on Bill's chest, but Sharon Stone got so into the scene, that the ice pick ended up piercing through the blood packs and penetrated his chest underneath in multiple spots. No one was aware at the time, except for Bill, whose screams of pain were real. Bill was later rushed to the emergency room and treated for puncture wounds varying from half an inch to an inch deep. Thankfully, he didn't sustain any serious injuries, but the incident left him with permanent scars on his chest.
- Follow the Leader:
- In the mid-nineties, every single thriller was Basic Instinct with some conceit.
- And this film itself was following Fatal Attraction. Not only is Michael Douglas playing the male protagonist in both films (and many of the same actors were considered for both roles), some could see Catherine as an Expy of Alex (many of same actresses were considered for both roles) and both films "good girls" are named Beth.
- Playing Against Type: In the Japanese dub, you don't expect someone like Sumi Shimamoto (in the NTV version, at least) a voice actress well known for voicing sweet, Yamato Nadeshiko-kind of girls or heroic girls like Nausicaä, Kyoko Otonashi, Kanata Izumi or Yuko Asou voicing someone like Catherine.
- Star-Making Role: For Sharon Stone.
- Throw It In!:
- Michael Douglas and Jeanne Tripplehorn were merely rehearsing the sex scene between their characters and didn't even know they were being filmed, but the director liked the footage so much that he put it into the film.
- As well as the infamous pantyless shot. Paul Verhoeven recalled a woman doing this to him years before to embarrass him and decided to put something similar in the film—it was never in the original script.
- Underage Casting: According to the original screenplay, the character of Gus was supposed to be 64. George Dzundza was 42.
- Wag the Director: Michael Douglas declined to go full frontal in the film, or to let his character be bisexual.
