Some of the films produced by Roger Corman's New World film company in the 1970s represent the best kind of B-movie, where the limitations of the genre actually act as a kind of freeing influence on the writers and directors  such classic drive-in films as "Deathrace 2000", "Hollywood Boulevard", "Grand Theft Auto" and "Caged Heat" emerged from this environment. Unfortunately, his former confederates at American International Pictures were running out of steam in the 1970s, particularly in the absence of Jim Nicholson, and they often produced second rate imitations of Corman's films, sometimes featuring his self-made stars. "Black Mama, White Mama" is one of those films. It's basically a cheaper imitation of "The Big Doll House with some of the same stars doing a lot of the same things. Yes, this is a John Ashley co-production (yes, the same John Ashley who was the hilarious Elvis wanna-be in "How to Make a Monster" and paired up with Debbie Walley in "Beach Blanket Bingo") with all the signature marks of his productions  women's prisons where everyone except maybe 2 or 3 lead characters including the inmates and the guards are Filipino actors in mostly non-speaking roles, where we see supermodel-type women taking on the roles of revolutionary militants, and where the primary joy of the film is derived through rudimentary S&M exploitation.<br /><br />The print I saw most recently was horribly light-damaged (good ole Will Viharo described it as "Yellow Mama, Yellow Mama"), but I think even in the best conditions the photography and directing are extremely routine. There's also very little visual value here Corman must not have had very much to do with the film itself because he was always canny enough to at least give his films some extra production value by filming in free public spaces that would make the film look more impressive. This film doesn't look impressive, it doesn't have an impressive soundtrack, and you just feel embarrassed for anyone who shows a shred of talent. The only remotely interesting performances come from Pam Grier as a feisty whore out to escape the life, Filipino actor Dindo Fernando as her grotesquely self-indulgent pimp, and Sid Haig as a cowboy styled mercenary. The story places Grier and co-star Margaret Markov in a low budget female version of "The Defiant Ones", but does very little with the melodramatic possibilities afforded by that premise. It's basically just an excuse to ensure that the two protagonists can still stop for a good mud wrestling match while they're trying to escape the prison together. This is all in the spirit of good fun, but the film ultimately fails even as exploitation because there's a certain edge and rawness that should be present in such scenes that is instead replaced under this director's hand with a kind of yawning predictability.<br /><br />So the film will have little value for fans of hard-core exploitation value  at least in the version I saw it's no more explicit than "Faster Pussycat, Kill! Kill!" from over a decade earlier, and far less interesting visually and thematically. For those who just enjoy getting a laugh out of "so bad it's good" films, this one might provide some fun but it's not in the upper tier. People would be more advised to seek out "Caged Heat" or some of the others that revel in their own brutality to the point that it becomes camp; this one is more similar to less ambitious efforts like Cirio Santiago's "The Muthers". Sadly, the best thing about this particular film is the title and the presence of Pam Grier, who was better in other films around the same time (particularly Jack Hill's "Coffy"). This film perhaps illustrates a midway point in Miss Grier's journey from Corman secretary to B-movie Queen-For-A-Day, but other than its historical "significance" as such it will have little value even to Grier's big fans because she is given very little to work with here.<br /><br />Worth skipping, unless of course you get to see it in a movie theater with a lot of friends and a lot of beer like I did. And even then its value is questionable.
