Elvira's Macabre Mobile was created for this film. The 1958 T-Bird hardtop was purchased for $2,500 and went through $7,000+ in alterations. The automobile remained in the possession of Cassandra Peterson, who occasionally used it for personal appearances, but she frequently complained that although it looked beautiful, it never worked well. In December 2021, Peterson auctioned off the steering wheel, license plate cover, hood and dashboard ornaments for a total of $19,795.
Cassandra Peterson's personal hand and body double for this film was Susan McNabb who was later assumed to be Peterson's sister at hundreds of Elvira's public appearances. McNabb retired as Peterson's personal assistant in 2005 after nearly 20 years.
Elvira's (Cassandra Peterson) dress is cut in a specific way and her hair is long in the back to hide burn scars Peterson has on her neck and shoulders from an accident in her youth. Peterson has joked that her Elvira costume only shows "the good bits".
Then-unknown Brad Pitt auditioned for one of the teenage boy roles, but Cassandra Peterson thought he was too cute and felt that Elvira would not be interested in Bob if Pitt was one of the teenagers trying to get her. On her casting notes of his audition, she wrote next to his name, "Yum Yum!" Later on, Brad Pitt would go to purchase her gothic styled mansion in Los Angeles.
The painting of Elvira's great-aunt Morganna Talbot is actually a painting of Cassandra Peterson, sans makeup and black wig. The portrait was painted by Robert Redding, who helped create Elvira's look, and to whom Peterson dedicated the film.
