What do you think of Mark Hamill's portrayal of Joker as opposed to Heath Ledger's, Jack Nicholson's, and Cesar Romero's? What about Batman's portrayals (Adam West, Michael Keaton, Val Kilmer, George Clooney, Christian Bale, and Kevin Conroy)?

Hmm, good question. Your forgot Lewis Wilson, he played Batman back in 43' ^.^

BUT anyway, I didn't like George Clooney. I thought he brought a very dimming light onto Batman. That and he sucked as Batman. He didn't have the raw toughness of Batman, that people before him portrayed. Therefore, my favorite Batman actors:

Lewis Wilson

Adam West (I love how he went from Cape Crusader to a moronic mayor in Family Guy)

Micheal Keaton

Val Kilmer (Okay with how he portrayed Batman)

Micheal Bale

Kevin Conroy

Now as for Joker. People who have played him have become severely depressed. Because of how Joker's mind set. I know when Jack Nicholson played him, he didn't act for a little while after that. But people who have taken the roll, such as Jack or Heath or Cesar or even Mark. They all did a wonderful job portraying the nasty villain of Batman. Though, I would love to see an actress play Harley, that would be interesting But yes I did like all of the people that played the Joker
