Depends on which Batman. The first Batman with Tim Burton was Micheal Keaton and Kim Basinger. The sequel to that had Micheal Keaton again with Michelle Pfieffer as catwoman and Danny DeVito as the Penguin. In The other lame batman movies they had George Clooney and Val Kilmer. In The Dark Knight Batman was played by Christian Bale, the Joker was Heath Ledger
