13 candidates the 'Dark Knight' director should consider before sealing any deal
Best known for: "The Wrestler," "Black Swan"
Pros: While know for his critically acclaimed indies, he's been chomping at the bit to do something bigger. Oh, and yeah, he's a visionary.
Cons: Can his ego mesh with Nolan's? (No, we're not kidding.)
Chances: Perhaps better than anyone thinks. Certainly better than Aronofsky doing "Wolverine 2."
