"Women's Prison" (1955)

High camp B-movie heaven. This one has it all: wisecrackin' broads and dames behind bars, a goon squad of hatchet faced prison guards, a vulpine Ida Lupino as the viciously sadistic warden, and for the finale, a plot by the inmates to take over the whole joint. Add in Howard Duff as the kindly prison doctor who wants to help these wayward ladies and some howlingly good/bad dialogue and you've got an even better "Orange is the New Black"...only in black and white.
