Sissy Spacek is tormented daily (most memorably in a shower-room scene full of naked high-school girls), then just when she’s made to feel special (via rigged prom queen vote), down comes the pig’s blood and out pours the psychic rage (school fire), which later also takes out her tormentors (car crash) and her mother and herself (collapsing their house). A classic for obvious reasons. Spacek was memorably nude in Prime Cut also, and probably in Badlands but I don’t remember. She was 26 in this so it’s okay to get naked.
