9. LIV TYLER AS BETTY ROSS

Love interest: Bruce Banner a.k.a. The Hulk
Betty Ross isn't a pesky journalist in 2008's The Incredible Hulk, nor an emotional actress; she's a female scientist who's trained to experiment on and handle big weapons. In the later versions of the comic, she is even resurrected as She-Hulk. Now we understand why she was so at ease with her green hero; if there's anyone who can take the ginormity of the Hulk's appendages, it's a woman just as big. Um, pause.
