Hercules vs. Vampires

Hercules vs. Vampires is an opera by composer Patrick Morganelli. The work is written as a companion piece to the 1961 film Hercules in the Haunted World.

Premise
The work integrates the 1961 film by projecting the film in its entirety behind the action on stage. However, the soundtrack of the original film is replaced with Morganelli's music. The performers on stage sing a libretto adapted from the 1961 film screenplay by Mario Bava, Sandro Continenza, Franco Prosperi, and Duccio Tessari in sync with the projected film.
