 According to director John Coney (I), the film utilized a sound  stage that was controlled by Artie Mitchell and Jim Mitchell  (IV), who were concurrently filming  _Behind the Green Door (1972)_ (qv). The production teams from both  films shared the sound stage expenses, as well as the sound stage  itself: the riser on which the Arkestra performed was also used by  the Mitchell Bros. for "other purposes."
