It was previously reported that Joseph Gordon-Levitt was appearing in Christopher Nolan’s 2012 release “The Dark Knight Rises,” but no one knew which part he was playing. We were speculating it was either the Riddler or Robin.
But Comic Book Movie has reported that an insider tells them JGL is cast as Alberto Falcone, son of mobster Carmine Falcone. Carmine made an appearance in “The Dark Knight” (played by Tom Wilkinson) and in the DC universe, Alberto becomes a serial killer called the Holiday Killer, who is (naturally) an enemy of Batman.
In the comics, Alberto was born on Valentine’s Day and when he starts killing citizens of Gotham, he attacks on holidays, hence his name, starting with Halloween, then Thanksgiving, Christmas, New Year’s, Valentine’s, St. Patrick’s Day, April Fools, Mother’s Day, etc.
