Christopher Nolan's highly anticipated sequel to The Dark Knight, which is currently called Batman 3, is not on the official agenda for this weekend's Comic-Con, however, First Showing is reporting that a studio casting grid has listed The Riddler as a character and that Joseph Gordon-Levitt is being eyed for the part.

Sources warn that this is at the stage of rumor, and nothing has been confirmed. Also, the age range listed for the character is 35 to 45, and Gordon-Levitt is 29 years old.
