Produced by Roger Corman, "The Big Doll House" is a sweaty, salacious slice of women-in-prison exploitation that helped kickstart the whole "babes behind bars" subgenre. Shot in the steamy Philippine jungle, this grindhouse classic follows a group of gorgeous inmates plotting their escape from a brutal tropical slammer. Featuring a young Pam Grier, mud wrestling, sadistic guards, and ample T&A, it's a veritable checklist of 70s exploitation tropes.
