4. Billionaire Playboy
This can be a tough part to nail. To convincingly portray the Dark Knight at every level, one cannot simply strap on a dark mask with pointy ears, and in a gravely voice proclaim you aren't wearing hockey pads, one must also be able to play the alter ego to a tee. To hide his nocturnal vigilantism, billionaire Bruce Wayne acts a fool as a womanizing playboy to throw any snoopers off the scent of discovering his true identity. While some have done better than others on film, Ben Affleck may just have the Hollywood-style good looks and boyish charm to convince Gotham and theatre-goers alike of his rich-boy facade.
