Auto Focus is a 2002 American biographical drama film directed by Paul Schrader and starring Greg Kinnear and Willem Dafoe. The screenplay by Michael Gerbosi is based on Robert Graysmith's book The Murder of Bob Crane (1993).Auto Focus tells a dramatized story of the actor Bob Crane, an affable radio show host and amateur drummer who found success on Hogan's Heroes, a popular television sitcom, and his dramatic descent into the underbelly of Hollywood after the series was cancelled and he formed a friendship with John Henry Carpenter.

Carpenter was later tried, and acquitted in 1994 of Crane's murder. Although the crime remains officially unsolved, Carpenter has remained the main subject of suspicion even after his death in 1998.
