The set used for the Partmiter home, where 'Joanna Miles' 's character has her head set ablaze by a "bug", was the same set at Paramount Studios in Hollywood as the one used for the interior of the Brady home in ABC-TV's The Brady Bunch (1969). Due to very poor ratings, the series had been canceled in 1974, a few months before filming on this film began. Since this film's release in 1975, "The Brady Bunch" became a ubiquitous hit in syndication, and the set has become easily recognizable to several generations of classic TV watchers, even though the set was altered for use in this film.
