But seriously... I wish they'd pick an actor to play Batman who actually resembles the comic book Batman/Bruce Wayne. I'd prefer if they picked an unknown actor to define the character onscreen, and didn't pick a known actor (like Affleck, or even Christian Bale) who bring their own pre-existing personality (and baggage) to the character.
Batman sells because he's Batman. You don't need some big-name actor to draw attention to a Batman movie.
