An important American film, co-starring Perry King, who also stars in the trash cinema classic "Bad" (1977). Almost certainly an influence on Tarantino's "Django Unchained"! I actually liked this one more. And at the time it was released there were extremely trashy television ads for it, I wish i could see those again but there's a trailer here that will give you a taste: https://www.youtube.com/watch?v=SF1TmC-k-Gg
Unflinching Southern gothic melodrama, gorgeously filmed with a sweaty, grotesque atmosphere oozing from each frame. Far more than just a "camp classic", this is an anti-Gone with the Wind that isn't afraid to stare the ridiculousness of slavery and racist hysteria straight in the face.
