Nightmare Circus aka The Barn of the Naked Dead or Terror Circus is a 1974 horror film directed by Alan Rudolph under the pseudonym of Gerald Cormier, and cowritten by him and Roman Valenti.
DVD Verdict panned the film, commenting that it was just dull and dumb. In the book Cult Horror Films Welch Everman criticized the movies attempt to contain what he saw as phony feminism, as he felt that it was added as a way to allow viewers to enjoy the movies violence against its female protagonists and not feel guilty afterwards. AllMovie gave the film a negative review complimenting the films premise, but criticized the films failure at delivering the kinky delights it promised, slow pacing, and lack of character development, calling the film an amateurish mess of sex fantasy and nuclear horror.The film was first released on DVD by Legend House LLC on January 29, 2008. It was later rereleased by Shriek Show and Code Red on March 31, 2009 and September 27, 2011 respectively with Code Red releasing the film as a double feature alongside the 1981 horror film Scream. ........
