Fresh off the success of his recent collaboration with Christopher Nolan in Inception, Joseph Gordon-Levitt is reportedly in talks to join the cast of The Dark Knight Rises.  Since the former child actor showed he could hold a leading man role all on his own in (500) Days of Summer, his schedule has been piling up. This April, we’ll see Levitt teaming up with Natalie Portman and Rainn Wilson in Hesher. Later this year, Levitt will battle cancer in the comedy Live With It. Next year he’ll join Bruce Willis in the futuristic mob film Looper, and headline the David Koepp (Ghost Town) thriller Premium Rush.It seems there’s nothing Levitt can’t tackle, but the question of the day is: what will his role be in The Dark Knight Rises? We know Hathaway is set to strap on the Catwoman getup and Tom Hardy will become the brute force known as Bane, but how will Levitt complement this cast? (Deadline's report is short on details.) Out of all the characters in the Batman universe, which one do you think Levitt should embody?  The Dark Knight Rises opens on July 20, 2012.  Click here for all our previous Batman coverage.
