Drive-In Massacre is a 1976 horror movie starring Bruce Kimball (as Jake Barnes), Adam Lawrence, Douglas Gudbye, Verkina Flower, and written by George 'Buck' Flower (as Buck Flowers), John Goff, and Stu Segall (as Godfrey Daniels), and directed by Stu Segall, with make up effects credited to 'the Duke of Disguise'. Co-writer John Goff allegedly has a cameo in the film, but this is unconfirmed.
The title is shown as though it were written in letters on the marquee of an actual drive in theatre.
The plot begins on August 10 in a California drive-in theatre, and concerns a killer on the loose, with the victims beheaded with a large sword. Two policemen are sent to investigate the killings, and question the owner of the drive-in, his assistant and a local peeping Tom, before going undercover to catch the killer themselves.
The original video release also includes the theatrical trailer, in which the title is misspelled as Drive-In Masacre. This was retitled 'Drive-In Killer' for its West German release.
The film was released on DVD in the United States in 2007.
