Dante lent the studio $50,000 worth of his magic equipment.

Final film of actresses Pauline Garon, Marguerite Churchill and Marie Osborne.
According to a news item on Los Angeles Daily News, this film is based on a book by Reginald Taviner entitled "Fortuneer", and on the film "Crime Ring", a 1938 RKO release for which Taviner wrote a screen story. Other sources, however, list Taviner's story for Bunco Squad as unpublished. It is not known if Taviner wrote additional material specifically for "Bunco Squad". The LADN item also noted that the film incorporated "material from recent files of a Los Angeles bunco squad."
