Fatal Instinct is an Airplane-style spoof of the late-'80s, early-'90s cycle of erotic crime thrillers. Setting the plot in motion is a kinky murder. Armand Assante plays the cop assigned to the case; he's also the prosecuting attorney; the "Sharon Stone" part is essayed by Sean Young. A dash of Body Heat is thrown in the pot as Assante's wife Kate Nelligan plots her hubby's demise. Tony Randall has a bit as a judge, while the film's semi-mocking jazz score is provided by Clarence Clemmons -- who shows up on screen to toot his sax at various crucial plot junctures.
