Batman mania...

EW : There's an old joke about how Superman is the guy girls want to marry but Batman's the one they want to date.

Nolan: Michael Caine had a great line: "Superman is the way American sees itself, but Batman is the way the world sees America." Batman is kind of this benevolent billionaire , with the power of the wealthy. [He's not] a godlike figure like Superman. He's one of us.
