Caged Heat (alternate title: Renegade Girls) is an exploitation film from 1974 of the "women-in-prison" film genre. It was written and directed by Jonathan Demme for New World Pictures, headed by Roger Corman. The film stars Juanita Brown, Roberta Collins, Erica Gavin, Ella Reid, Rainbeaux Smith, and Barbara Steele. John Cale wrote and performed its soundtrack music, which features the guitar playing of Mike Bloomfield.
The film was Jonathan Demme's debut as a film director. Producer Roger Corman thought that the content of his company's previous "women in prison" films was inadequate, so he instructed Demme to create a screenplay that would bring something novel to this genre. However, Corman also wanted Caged Heat to retain most of the violence and nudity that audiences for this genre had come to expect.
Demme introduced new aspects to Caged Heat, including a satirical approach and making the sadistic warden female instead of male. To a lesser degree, Demme also incorporated elements of liberal politics, feminism and social consciousness into his screenplay. Because of all these new elements introduced to the "women-in-prison" genre, and because of the film's status as Demme's first feature, some movie critics consider it to be more interesting than the run-of-the-mill, women-in-prison exploitation movie.
