I could see Edward Norton being some sort of villian too. The dude could pull it off.
And Lord Simen, I see where you are coming from but recasting the Joker would fucking suck especially in the same trilogy.
I WASNT one of those people saying Jack couldnt be topped. I thought Heath was a brillant choice. With that said, I just think they should somehow make a storyline that the Joker is locked away for good and will never be seen again.
And get a different villian entirely.
