Now that you bring it up...I heard a rumor around the time of the Schumacher films that they would bring back the Joker in that series of films, with those rumors even going as far as stating that Jack Nicholson would reprise that very role, though I'm glad that rumor never came to life; Schumacher would've screwed up the Joker's character the way he screwed up the two films he directed. Under Schumacher, we would basically be seeing the Joker from that 60s TV series.
