I have to say that I enjoyed this more than the testosterone-fuelled man-movie "Brute Force". It was more nuanced in it's portrayal, more balanced. To me it was more Noir too - we follow the lead from a scared, new-fish, innocent girl, through a huge change to the hardened and cynical woman who leaves the prison a scant 15 months later: in true Noir style she pays for her mistake in the past, not with death but with an obvious descent from good to bad, and the prospect of ending up like the old lifer who tried to turn her away from her path into crime.
Eleanor Parker was excellent too in portraying this change. You physically see her getting stronger and more hard-boiled as the film progresses, her voice altering to match that change.
My favorite part: the very end. Almost wordless, she exits the prison - and movie - to her life of vice: sleazy movie breaks in and she flicks away her cigarette in a tough-guy manner before climbing into a car with 4 strange men and off to her new life. Excellent film.
Yes, Caged is an excellent film. Eleanor Parker does some fine acting and her transformation is a classic noir theme.
Parker is a beauty but that doesn't get in the way in this gritty film.
