The film centers on Dracula's plot to convert Billy the Kid's fiancé, Betty Bentley, into his vampire bride. Dracula impersonates Bentley's deceased uncle, calling himself "Mr. Underhill", and schemes to make her his vampire bride. A German immigrant couple comes to work for her and warns Bentley that her "uncle" is a vampire. While Bentley does not believe them, their concerns confirm Billy's suspicions that something is not quite right with Betty's uncle.
Eventually, the Count kidnaps Betty and takes her to an abandoned silver mine. Billy confronts the Count, but soon finds that bullets are no match for a vampire. The Count subdues the notorious outlaw and sets out to transform Betty into his vampire bride. Just then, the town sheriff and a country doctor arrive. The doctor hands Billy a silver scalpel, telling him he must drive it through the vampire's heart. Billy throws his gun at the vampire and knocks him senseless, making him easy pickings for a staking. With the Count destroyed, Betty is saved and Billy takes her away, presumably to live happily ever after.
The film was announced for production as early as June 22, 1965, in Daily Variety announcing both Billy the Kid Versus Dracula and Jesse James Meets Frankenstein's Daughter.[1] Principal photography began on June 22, 1965.[1] Both films were the last features directed by William Beaudine, Sr.[1] Beaudine spent the rest of his career after these films by filming television.[3] The film was completed on July 9, 1965, and was completed with a budget surplus of $25,000.[1] Each of the two features was shot in eight days in California's Red Rock Canyon, Corrigan Ranch, and Paramount Studios.[3] According to the assistant to the producer Howard W. Koch, Jr., they "were made as cheap as movies can be made."[3]
According to the American Film Institute, an official release date of the film is not confirmed.[1] The film was shown as early as March 30, 1966, in New Haven, Connecticut.[1] Box-office reports in the September 28, 1966, issue of Variety stated that it was featured on a double bill that month as a reissue in St. Louis, Missouri.[1]
Billy the Kid Versus Dracula was released on DVD by the label Cheezy Flicks on October 25, 2005, and again on DVD by Cheezy Flicks in a compilation titled Shockorama: The William Beaudine Collection.[4] The film is set for release on blu-ray and DVD by KINO Lorber Studio Classics on August 20, 2019.[4]
John Carradine later spoke on the film, "I have worked in a dozen of the greatest, and I have worked in a dozen of the worst. I only regret Billy the Kid Versus Dracula. Otherwise, I regret nothing." And again: "My worst film? That's easy, a thing called Billy the Kid Versus Dracula...It was a bad film. I don't even remember it. I was absolutely numb!"[5] Critic and historian Tom Weaver stated that the film could have earned "the semirespectability" of Curse of the Undead, another vampire-themed Western "if it [were] truer to vampire lore, if it didn't feature a 'name' outlaw like Billy the Kid, if the vampire in it weren't Dracula, and if Carradine's performance [were] much better. (That's a lot of ifs.)"[5]
