Original Story:Hollywood Life reports that while working on the film Inception with director Christopher Nolan, Joseph Gordon-Levitt mentioned that he'd love to audition for The Riddler in Batman 3.
Apparently, this sort of talk continued and the site now says that Levitt is being considered by Nolan for the part.
This unnamed source then went on to say:
David S. Goyer is presently hard at work writing the screenplay for the next installment in the Batman saga.
The Dark Knight Rises was released July 20th, 2012 and stars Tom Hardy, Christian Bale, Anne Hathaway, Liam Neeson, Joseph Gordon-Levitt, Gary Oldman, Marion Cotillard, Morgan Freeman. The film is directed by Christopher Nolan.
