Sharon Stone

She is knwon for portraying a crazy hottie more than once. She does, afterall, fit the role of a highly attractive, psychopathic killer to the tee.

The film that did the trick for her was Basic Instinct of course, where Sharon Stone was a Black Widow type character who was hell bent on sleeping with a police officer before she kills him. A far from likely concept perhaps, but definitely one of the sexiest whack job women we've ever seen in real or reel life!
