Bob Kane's comic book hero Batman was first introduced in Detective Comics #27 back in 1939. With Christian Bale retiring from playing Batman next year he follows a long line of actors who have put on the cape and cowl.

Who played Bruce Wayne first? Who played him the longest?
Who's your favorite Batman actor?
