The Batman: Arkham Asylum video game is what many fans hope for from a future Batman movie, and Rocksteady's take on The Joker would potentially work very well for Jared Leto. Despite having the gaunt and stylised face of the classic comic book Joker, this version was also very realistic in some ways. His mouth for example is pretty much completely normal, with the lipstick/make-up responsible for giving the impression that it's much larger. The fact that his clothes are grubby and worn looking could be perfect if Suicide Squad features a Joker who has been in captivity for some time, and little touches like his bow tie being a little loose and the flower on his suit being dead would make for an interesting visual. This is a Joker who just looks frightening, and Leto could do a lot worse than turning to Mark Hamill's take on the iconic villain when it comes to finding his inspiration.
