Celebrity Paris Hilton will sing in a futuristic thriller, alongside actors Alexa Vega and Paul "Goodfellas" Sorvino in the cast of "Repo! The Genetic Opera," a musical feature co-financed by "Saw" makers Twisted Pictures and Lionsgate.
The film is set to shoot in Toronto this fall.
Darren Lynn Bousman, director of the last three "Saw" films, has spent years developing a movie version of the opera, with screenwriter/composers Darren Smith and Terrance Zdunich.
Dan Heffner and Twisted's Carl Mazzocone, Mark Burg and Oren Koules are producing.
Setting of the film is 2056, when a plague nearly destroys the human race and survival is dependent upon being able to finance organ transplants.
Hilton will play the daughter of evil organ transplant magnate (Sorvino).
Aside from her run in the reality show "The Simple Life," Hilton previously acted in the films "House of Wax" and "Raising Helen."
