Casting chocies of Harvey Dent/Two Face
My mian pick is Oscar Isaac: Like Billy Dee Williams, I wouldn't mind another Star Wars actor playing Harvey Dent and that is Isaac, who is a great actor and can pull off playing a bad guy and also authority figures.
Jack Huston: I heard his name a while back for Batman last year, it was said that Matt Reeves wanted him for Batman, but would like him in a different role so Two Face might suit him. Huston is capable of pulling off any role (exclude Ben-Hur)
