Daniel Day-Lewis
What? A man can’t dream? I know the chance of Day-Lewis using his acting chops in a comic book movie seems very slim, but he is the greatest method actor alive, hands down. He also has a face that is just full of character. Eyes that look like they have seen so much and sunken cheeks that make him look like he is always on the verge of starving himself to death.
There is also the simple fact that NO ONE can be as intimidating as Daniel Day-Lewis. I mean, Bill the Butcher from Gangs of New York? Think about that level of manic energy applied to The Joker. Even bits of his character from There Will Be Blood would be perfect. A man on a mission, with little to no regard for who or what stands in his way.
Aside from the simple fact that we all know this is just me dreaming out loud, we also need to factor in risks for method actors who take this part. I know that sounds silly, but a guy like Daniel Day-Lewis BECOMES every character he plays. The last time someone did that with the Joker, it killed him.
