Sean Young may have famously -- and insanely -- campaigned for the role (Madonna was also considered), but Tim Burton chose Pfeiffer to play super-hot Catwoman and her alter ego, the bespectacled and buttoned-up Selina Kyle, for 1992's "Batman Returns." Pfeiffer went through 60 cat suits (at $1,000 each) and had to put a live bird in her mouth. But the big news? She and Michael Keaton embarked on what's been described as a "very stormy affair." (While Pfeiffer was single at the time, Keaton was in a relationship with Courteney Cox, which lasted from 1989 to 1995). Pfeiffer and Keaton's chemistry shone through in the film, as they won Best Kiss at the MTV Movie Awards.
