1. Marc Webb
Fills out a good application for the role after having previous experience working with Joseph Gordon-Levitt on (500) Days of Summer, a film which catapulted them both in to the public conscious.
An important part in helping continue the Batman legacy is have the potential lead, assuming it’s going to be Joseph Gordon Levitt, have trust and a good working relationship with the director to tailor the movie around these needs.
He’s also just finished work on The Amazing Spider-Man and did the very un-Marvel thing of making a movie that doesn’t feel like a colourful kids show. His reboot of The Amazing Spider-Man was visually stylish, kinetic and emotionally charged and shows good credentials for the future; he could further the emotional strength of the Batman films whilst his different style of more motion and energy than Nolan would be a good distinguishing factor between the old Batman and the new one.
Although everyone would like Nolan to continue; it’s now a different story with a different character and a new style is needed to add diversity.
