1. Susan Sarandon and Catherine Deneuve in The Hunger (1983)
It might to be hard to imagine Susan Sarandon as a P.Y.T., but if you need evidence, look no further than The Hunger. Nubile she-vamp Miriam (Catherine Deneuve at her sexiest) seduces Sarah (Sarandon), who uses a little spilled wine (on her white shirt, no less) as an excuse to do a little strip tease.
Deneuve pounces on Sarandon (who is sprawled across the bed for her your viewing pleasure) and her mouth serves as the tour guide for Sarandon's twin peaks. It's a moment so memorable that not even the gauzy light and opera soundtrack can take away from the steaminess of it all.
