9. Catherine Tramell (Basic Instinct Movies)
Crime novelist and sexual predator Catherine Tramell (Sharon Stone) is someone you don't want to cross. Her forte is enticing men to bed, having sex with them, then stabbing them to death with an ice pick - kind of like a black widow. She is cool, calm and collected throughout the investigation and interrogation (we all remember that scene), which makes her even more dangerous. She's a real ice-maiden. Of course, one way to try to save yourself from certain death, if she does get you in to her bed, is to satisfy her sexual desires, like Detective Nick Curran (Michael Douglas) did - that way, she might just spare your life. However, the best way to guarantee your safety is to stay well out of her way entirely.
