3. Poison Ivy: the Car Hookup
The Couple: Drew Barrymore and Tom Skerritt
The Scene: This scene, which involves Ivy completing her seduction of her best friend's father, Darrel, on a rainy day on the roof of a car, is one of the steamiest and creepiest in the entire film. Drew Barrymore wasn't quite an ingenue at this point in her career, and as evil seductress Ivy, she definitely knew what she was doing.
What's So Sexy about It: The fact that it's so forbidden makes this scene sexy – and a little skeevy, to be perfectly honest, except you can see how torn Darrel is even at this point in his infatuation.
