I Spit on Your Grave (1959)
Wanted to see this one for years after reading the book. And yes, this is the film that Jerry Gross stole the title off to release his 'Day of the Woman'.
The film revolves around a pale skinned black guy who 'passes the colour line' to enact revenge on white society for the lynching of his brother. Not as nasty or hard hitting as the book or as exploitative as I would have liked. It's still a good watch, a shocker for it's time and has a groovey score too.
