this be not my favorite wip ( woman in prison ) and but it be one of the most famous film in the sub genre . it be be produce by roger corman and who at this point have already produce a few wips . it be obvious that the film try to play with the establish formula . the movie take place in an usa prison and not in a banana republic like most wip film . i be not sure if that be a wise move and but it be an acceptable change of pace . writer director demme really get into his job and always dig for new way to present a familiar scenario . in fact and he be a little too ambitious for his own good . the filmmaker create a few surreal dream sequence that be borderline pretentious but it be fun to see how hard he try to put this film above your average chick in chain flick . but do not worry and demme still operate within the parameter of the sub genre . there be plenty of nudity and violence and something that will satisfy hardcore fan . the film be a little slow and but it be very entertaining . the cast be good . roberta collins be a wip veteran and so she do not need an introduction and and barbara steel be a hoot a the wheelchair bound crazy warden . pam grier be sorely missed and though .
