UPDATE: We got news over the weekend revealing which character JG-L will be playing. Rampant speculation had Robin, The Riddler, and Hugo Strange as potential bad guys for the Inception star, but word comes down that Joseph Gordon-Levitt will portray Alberto Falcone, son of mob boss Carmine Falcone who, you'll remember, was offed in Batman Begins.
Falcone is also known as the Holiday Killer, and is a sworn enemy of Batman. Alberto Falcone is featured in the Jeph Loeb and Tim Sale series' Batman: The Long Halloween and Batman: Dark Victory. Though the character is loosely patterned after Fredo Corleone (John Cazale) of the live-action Coppola Godfather series of movies, he also harbors certain traits similar to Michael Corleone, who was played by Al Pacino.

Buzz around the web has long tickled the idea of Joseph Gordon-Levitt joining his Inception filmmaker in the forthcoming The Dark Knight Rises film to possibly play The Riddler or even The Joker.
But while director Christopher Nolan has said there will be no joker in his film, he did recently tell Deadline that Gordon-Levitt will indeed be joining the cast of the new Batman movie. No word yet on which character he'll play, however.
