Above is an Italian poster for the American financed, Philippine shot sexploitation actioner The Big Doll House, which starred Roberta Collins, Brooke Mills, Pat Woodell, Pam Grier, and Judy Brown. This wasn't the first women in prison movie—those had been appearing for decades—but it was the one that got the ’70s prison sexploitation ball rolling in the U.S. It offers a full slate of whippings, waterboardings, overheated isolation, and bizarre snake tortures, orchestrated by the evil wardeness Christiane Schmidtmer. Collins leads the beautiful convicts' eventual escape from bondage and hers is the most memorable character in the ensemble, though all the personalities are interesting. Don't get us wrong—the acting is of course atrocious, and the production values aren't high, but that didn't bother us and it didn't bother American audiences either. They made the movie a hit and the women-in-prison conveyor belt quickly cranked out other Filipino bondage productions like Women in Cages, The Hot Box, The Woman Hunt, The Big Bird Cage, and many others. The Big Doll House wasn't the best of the lot, by any stretch, but hey—being a trailblazer matters. We think it's worth a viewing.

What a difference four years makes. Talent-wise, the Claudia Jennings from the 1972 rags to riches flick Unholy Rollers is not remotely in the same league as the one from 1976’s Dynamite Women, which we discussed here. If Jennings ever had acting lessons, she must have driven to the first one ten minutes after Unholy Rollers wrapped. Some difficulties stem from poor scripting, editing and directing, but those problems take a backseat to the fact that Jennings simply hadn’t had enough dramatic training when she starred here. We recommend this one only for fans of Jennings and/or roller derby. Unholy Rollers premiered twenty-nine years ago today, and above we have probably the best part of it—the kick-ass promo poster painted by Aller, aka Carlo Alessandrini, for the movie's Italian run.

When Pam Grier goes bad, she goes all the way bad. In the Roger Corman produced Women in Cages, she’s the head matron of a hellhole prison somewhere in the Philippines and spends the movie permanently covered in a sheen of sweat as she sneeringly tortures her beautiful female convicts. The girls endure every manner of humiliation—the rack, rats, snakes, the hole, leeches, electric shocks, and some really harsh words. Oh, and the whole prison is basically a racket to sell the women into sexual slavery, so there’s that problem too.

After enough of this treatment the jailbirds finally decide it’s time to escape into the jungle, but unforeseen circumstances result in them taking Grier hostage, leading directly to her death via gang rape and strangulation. The audience is supposed to feel she’s gotten what she deserved, but all we felt was our lunch coming up. Such are the vicissitudes of '70s b-cinema.

Women in prison movies are misogynist by definition, but there is still a line somewhere and, though it’s difficult to know exactly where it is, it isn’t difficult to know when it’s been crossed. Anyway, once Grier has been disturbingly dispatched, the escape takes a few more turns which we won’t give away. We’ll just sum up by voting thumbs down on this one, and footnote by adding that we’re glad Pam went on kill so many men in her later movies. Women in Cages premiered in the U.S. today in 1971.
