In l933, Richard Hollingshead invented the drive-in movie theatre, a cinema for Americans infatuated with the automobile. For fifty years, the drive-in asserted its place in American culture as a mecca for families and restless teenagers. Today, the "passion pit with pix" has become a dinosaur. Drive-In Blues celebrates the drive-in and laments its decline. A blank white screen looms behind interviews with old-time theatre owners who reminisce about the heyday of the drive-in as they confront the reality of a dying business. Laced with unusual archival trailers, the tone of the film swings between camp and nostalgia.
