Rockula is a 1990 American comedy horror film directed by Luca Bercovici and written by Bercovici, Jefery Levy, and Chris Ver Weil. Dean Cameron stars as the vampire Ralph LaVie, Toni Basil plays Phoebe LaVie, Ralph's mother, and Thomas Dolby is the villain, Stanley. The story centers on a vampire under a curse; the tagline for the film is: "He's a vampire that hasn't scored in 400 years—tonight's the night!".

Bo Diddley plays a supporting role as Axman, the guitarist in Ralph's band, which is incidentally named Rockula. The director of photography was John Schwartzman, later the DP on Seabiscuit and Saving Mr. Banks.

In the film, Ralph is a vampire who was born in the late 16th century. In the 1680s, Ralph was involved in a romantic relationship with the mortal girl Mona. Mona was killed by a pirate, who happened to be her jealous ex-boyfriend. Mona is reincarnated every 22 years but keeps getting killed by pirates on the anniversary of her original death. Ralph has been romantically involved with each of Mona's incarnations but has been unable to prevent the series of deaths. In the early 1990s, Ralph courts a young singer, who happens to be Mona's latest incarnation. He seeks a way to end the curse, while starting his own musical career in an attempt to work alongside his love interest.
