My Super Ex-Girlfriend

This Super Hero movie takes a decidely different approach. He's a regular guy with the hots for a woman at work, but she has a boyfriend. Instead, he strikes up a relationship with a meek woman on the train, and things go well. It turns out that she is actually a Super Hero with super strength. After a while he decides that he actually does prefer the woman at work, and dumps his super girlfriend... which turns out to be a big mistake, as hell hath no fury as a woman scorned. And when the scorned woman has super-human powers, you'd better watch out...
