Oh dear.
Nicholson was great and all, but he was playing HIS Joker. That was his take on the character.
Mark Hamill's Joker was better, because he was more genuinely funny and dangerously likable.
Both were great, but to say Nicholsons was the best is crap. He based his Joker off of Romero's anyway, the character isn't TOTALLY his.
Nicholson was great, but I think there would be more than a few budding actors out there who could do an even better job.
And, for the last time, Begins is not a prequel. This is really bugging me as to how people can be so stupid. They will be doing The Joker again. Wasn't it obvious from watching Begins that this is a clean-slate beginning? How can Batman make his first appearance twice? Dear God, we're dealling with a special breed.
Besides, the script from Begins was fantastic, with some great humour. I'm sure the Begins sequel will have a hilarious script for the Joker. I genuinely want to see Hamill's Joker more than Nicholsons, because I always thought the Animated Series Joker deserved his own damn movie anyway.
