Sharon Stone
Sharon Stone is a star who is not normally cast to play characters that are smart. In fact, in movies such as Silver, Casino, and Basic Instinct, she is often cast in sexual roles. She is all the evidence you need to know that looks can be disappointing. Mind you, 148 is the IQ of this great actress.
Mayim Bialik
Mayim Bialik is an actress best known for her work in Blossom and The Big Bang Theory. Her IQ has yet to be confirmed because a source said 150 while another said 163. There is no arguing, at any rate, that she is a bright woman. She actually earned a Ph.D. from the University of California Los Angeles in 2007 in neuroscience. She was clearly the best person to play her character in The Theory of the Big Bang!
