 Screenwriter Wallace MacDonald (qv) said in an interview that he  dreamed up the film, complete with character names, plot ideas,  costumes, etc., after he was sedated by nitrous oxide while  undergoing dental work. When he awoke he went directly home, put  everything down on paper, and brought it to producer  Nat Levine (qv) at Mascot Pictures, who loved the idea and  approved the production.
