actor: heath ledger

Heath is one of those actors who, in his best work, completely transforms himself and that sort of consumes his star quality. He’s creating something that’s entirely original for himself and so he’s never done anything like this before. I can’t say that I was hugely surprised or worried about the reaction because whoever we would’ve cast, it’s going to be tough for people to know how the palette is going to work. Particularly with Heath, who’s dredging something up from a side of himself that you’ve never seen before.

— Christopher Nolan on Heath Ledger as the Joker in The Dark Knight (2008)
