Body Heat is a 1981 American neo-noir erotic thriller film written and directed by Lawrence Kasdan in his directorial debut. It stars William Hurt and Kathleen Turner, featuring Richard Crenna, Ted Danson, J. A. Preston and Mickey Rourke. The film was inspired by the classic film noir Double Indemnity (1944), in turn based on the 1943 novel of the same name.

The film launched Turner's career—Empire magazine cited the film in 1995 when it named her one of the "100 Sexiest Stars in Film History". The New York Times wrote in 2005 that, propelled by her "jaw-dropping movie debut [in] Body Heat ... she built a career on adventurousness and frank sexuality born of robust physicality".
