Willem Dafoe should play The Joker
Willem is amazing in this 2013 9 mins short film "The Smile Man"

He'd be the best Joker ever. He is very close to the Arkham Joker and to Mark Hamill's Joker + he looks and acts like Conrad Veidt (who's character in the film "The Man who Laughs" 1928 was the inspiration for the Joker).
