Second of three movies Lon Chaney Jr and Vincent Price appeared in together. The first was Abbott & Costello Meet Frankenstein (1948) and last The Haunted Palace (1963)

Lon Chaney Jr and Bob Hope had appeared in My Favorite Brunette (1947) together.

Lon Chaney Jr and Raymond Burr had previously appeared in Bride Of The Gorilla (1951) together. They would again be reunited the same year in Passion (1954).
