No I dont know it I was just offering an opinion.Hey if he can do it I would LOVE to see Joker done right.Nicholson was ok but it was SO hammy that Joker lost his edge that made me love the character in the first place.I really WANT him to be able to pull it off but there is just something that makes me think he might not-sure Brokeback was a brave performance but the other material he has done is pretty lightweight.Sin Eater was just awful and Knight's Tale is pure fluff.I always thought Bale would make a great Batman and he did just a good a job as Keaton-who was always an under-rated actor.Like I say I really want the character to be done right and if Ledger can do it I will be the first to applaud him for it.
