When two trouble-making female prisoners (one a revolutionary, the other a former harem-girl) can't seem to get along, they are chained together and extradited for safekeeping. The women, still chained together, stumble, stab, and cat-fight their way across the wilderness, igniting a bloody shootout between gangsters and a group of revolutionaries.
From a story by pre-fame Jonathan Demme, this is partly an homage to the 1958 classic "The Defiant Ones", which structured the same type of situation for its leading characters, played by Tony Curtis and Sidney Poitier. Then we bring on director Eddie Romero, who was an actual Filipino director who worked primary in the Tagalog language. Well done, AIP, for not bringing in your own guy.
There were a number of jungle revolutionary films in the early 1970s, starting with Jack Hill's "Big Doll House" (1971), also starring Pam Grier. Actually, Grier was the queen of 1970s Filipino jungle women-in-prison films, also appearing in Hill's "The Big Bird Cage" (1972), plus Gerardo de León's "Women in Cages" (1971). Grier really made her name in these type of films before transitioning to "Foxy Brown".
Grier's co-star Margaret Markov also appeared in "The Hot Box" (again written by Jonathan Demme). She starred opposite Pam Grier again in "The Arena" (1974). She never quite reached the level of Grier because during the making of the latter she started dating producer Mark Damon (who had risen to fame through Roger Corman); the two later married and Markov retired.
The Arrow Video disc features an audio commentary with filmmaker Andrew Leavold, director of "The Search for Weng Weng". He loves to recommend the documentary "Machete Maidens Unleashed", and I would second that if you want to see how "Black Mama" fits into the whole Filipino action film cycle.
We also have new interviews with stars Margaret Markov and Sid Haig. Markov covers the entire breadth of her career, even spending time discussing Rock Hudson and Gene Roddenberry on "Pretty Maids All in a Row" (1971). Haig had many films in Philippines, so he has a few tales to tale. We are treated to a previously unseen archive interview with director Eddie Romero. (Exactly why an interview would have been filmed and not used, I don't know.) What is missing? An interview or commentary from David Sheldon, as on the disc for "Sheba Baby". Sheldon has contributed by far the best audio commentary in years, and we really need more of those from him.
