Winter Kills is a 1979 satirical black comedy thriller film written and directed by William Richert, based on the eponymous novel of 1974 by Richard Condon. A fiction inspired by the assassination conspiracy theories about President John F. Kennedy, its all-star cast includes Jeff Bridges, John Huston, Anthony Perkins, Eli Wallach, Richard Boone, Toshirō Mifune, Sterling Hayden, Dorothy Malone, Belinda Bauer, Ralph Meeker, Elizabeth Taylor, Berry Berenson and Susan Walden.

The film simplifies the plot of the book somewhat, emphasizing humor. It follows the events surrounding the assassination of the fictional President Kegan (based on John F. Kennedy). Several years later, Kegan's half-brother Nick (Bridges) discovers leads which suggest there may have been a plot to kill the President.
