Fatal Instinct is a 1993 American sex comedy thriller film directed by Carl Reiner. A parody of the erotic thriller genre, which at the time had reached its commercial peak, as well as being a pastiche of 1940s film noir and psychological thriller genres, in particular Double Indemnity, the film stars Armand Assante as lawyer/cop Ned Ravine who has an affair with a woman named Lola Cain. Kate Nelligan stars as Ned's wife and Sherilyn Fenn stars as his secretary. The film title is a combination of Fatal Attraction and Basic Instinct, both of which starred Michael Douglas.

Double Indemnity is a 1944 American crime thriller film noir directed by Billy Wilder, co-written with Raymond Chandler, and produced by Buddy DeSylva and Joseph Sistrom. The film was based on James M. Cain's novella of the same name, which ran as an eight-part serial in Liberty magazine beginning in February 1936.
