The Big Doll House (1971)
Cast: Roberta Collins, Pam Grier
The Big Doll House is a 1971 American women-in-prison film starring Pam Grier, Judy Brown, Roberta Collins, Brooke Mills, and Pat Woodell. The film follows six female inmates through daily life in a gritty, unidentified tropical prison. Later the same year, the film Women in Cages featured a similar story and setting and much the same cast, and was shot in the same abandoned prison buildings. A nonsequel follow-up, titled The Big Bird Cage, was released in 1972.
