Composer Jeff Simmons was a member of the L.A. freak band Easy Chair in the late sixties. His work on this movie came soon after the band broke up, and the band's drummer performed on the soundtrack.
During rehearsals, one of the actors/stuntmen was killed when a motorcycle gag went wrong. The filmmakers were forced to re-shoot all the scenes he'd been in previously, which was tough on such a low-budget production.
