The producers of the film wanted River Phoenix to play the lead. They approached him several times for the role, and kept increasing their offers, but he didn't feel a connection to the material and felt he was unsuitable to play the part, so repeatedly turned it down.
The original climax shot for the movie took place at the Carlsson Copper Factory, as it happens in Ira Levin's book, but it failed test screenings so the climax was changed to Jonathan's childhood home in Pennsylvania.
The film's director James Dearden had written the screenplay for Fatal Attraction (1987). Many movie posters for the film feature a slogan positioned above the names of the two lead stars reading: "From the creator of Fatal Attraction (1987)".
The movie was nominated for two Razzies at the 12th Golden Raspberry Awards in 1992. For her dual role as twins in this film, actress Sean Young won Razzies for both Worst Actress and Worst Supporting Actress. With this movie, Young became the first actress to be awarded two Golden Raspberry Awards in the same year.
First of two consecutive thrillers for actress Sean Young who in 1992 would star in the erotic thriller Love Crimes (1992). At the Golden Raspberry Awards Young again would be Razzie nominated for Worst Actress for the subsequent film having won the Award for this film (along with Worst Supporting Actress).
The movie's original ending was shot in a steel mill in Wales, that served as scenario for the Carlsson Copper Factory. After the ending failed test screenings, it was re-written and re-shot in Jonathan's childhood home in Pennsylvania. A few scenes of the original ending can be seen in the theatrical trailer: Jonathan and Ellen wearing helmets at the factory, Jonathan throwing an unidentified man off a crane and Jonathan chasing after Ellen. The trailer also shows unseen scenes such as Jonathan looking through a window blind and a door knob being forced while Jonathan hides behind it with a stretched rope. A few promotional stills for the film show a few more unseen scenes: Ellen and Cathy chatting in the street, Thor grabbing Ellen by her shoulders, Thor, Jonathan and Ellen standing next to a helicopter, Jonathan and Ellen wearing flowery shirts holding exotic drinks.
According to Edwin Jahiel, the movie "blends the style of 1940s and 1950's films noirs with several homages to 'Alfred Hitchcock', some devious, others obvious, like Ellen watching Vertigo (1958) on TV; or like references to Psycho (1960), notably in a steamy sex scene inside a steamy shower, and a close-up of the drain".
In the film's source novel and in the earlier movie version, the Jonathan Corliss character played by Matt Dillon was called Burton Corliss (nicknamed Bud) whilst the two sister characters were called Ellen Kingship and Dorothy Kingship (nicknamed Dorie), and are renamed Ellen and Dorothy Carlsson in this remake, both being played by Sean Young, and instead also, both are made twins. Moreover, in the source book there was a third sister called Marion Kingship, who, like with the first film, does not appear. The Jeffrey Hunter character, who appeared in the original movie, is removed in this remake.
