The Name of the Game Is Kill (1968)

Synopsis
Hawaii Five-O's Jack Lord stars in this odd little thriller directed by Gunnar Hellstrom. Lord plays a Hungarian man named Lipa who meets the beautiful Mickey (Susan Strasberg) while wandering the highways of Arizona. Mickey runs a gas station in the desert with her mother (T.C. Jones) and two sisters and invites Lipa to stay with them. He does, not knowing that the entire family is stark-raving mad. The usual psychological games ensue, with Lipa being attacked by a rattlesnake, seduced by the psychotic sisters, and run over with a car before figuring out the predictable truth -- that "Mom" is really a man. Gorgeous photography by Vilmos Zsigmond and some amusingly sadistic set-pieces accent this enjoyably trashy thriller. ~ Robert Firsching, All Movie Guide
