One of a cycle of thrillers made during the early 1990s which were set around husband and wife characters. The films include: Malice (1993), Deceived (1991), Shattered (1991), Mortal Thoughts (1991), Consenting Adults (1992), Unlawful Entry (1992), Presumed Innocent (1990), Guilty as Sin (1993), Sleeping with the Enemy (1991), and A Kiss Before Dying (1991).
Screenwriter Daniel Pyne once rented an apartment to a tenant that he could not evict. The film was inspired from this scenario.
The home of Melanie Griffith and Matthew Modine's characters is not in Pacific Heights at all, but right across town in San Francisco's Potrero Hill district at the corner of Texas Street and 19th Street.
In the original script, Carter (Michael Keaton) was a bisexual man who sexually threatens Drake (Matthew Modine) and Patty (Melanie Griffith).
Christopher Reeve unsuccessfully lobbied John Schlesinger personally for the "Carter Hayes" role.
Melanie Griffith didn't like the experience of filming this movie, and made some complaints about it while she was filming The Bonfire of the Vanities (1990), which started filming a few days after this film had been completed.
