I’ve been meaning to reread this one to find out if it’s as racist as it is reputed to be. The racism went over my head when I was 11 years old, and I loved it and it blew my mind.
I Drink Your Blood (1970)
A band of satanist hippies roll into a town and begin terrorizing the local folk. After raping a local girl, her grandpa goes after them, only to be beaten and forced to take LSD. His grandson then plots revenge on the satanists by feeding them meat pies infected with blood from a rabid dog. They turn into crazed lunatics and begin killing and/or infecting everything in their path.
So, basically a Disney movie?
