 Exteriors were shot on the Columbia Studios backlot (now part of the  Warner Bros. Backlot), the same lot as the exteriors for the TV  series _"Bewitched" (1964)_ (qv) and  _"I Dream of Jeannie" (1965)_ (qv). Many scenes were shot on  Courthouse Square at Universal Studios, which doubled as Hill Valley  in _Back to the Future (1985)_ (qv).
