The Holiday Killer — first introduced in the comics in 1996 — is known for killing on holidays and leaving behind a small item representing that holiday at every crime scene. Alberto is the son of organized-crime chief Carmine Falcone, whom Tom Wilkinson portrayed in 2005's Batman Begins.
The Dark Knight Rises will re-team Gordon-Levitt, 30, with his Inception director, Christopher Nolan, as well as his Inception co-stars, Tom Hardy and Marion Cotillard. Cotillard recently signed on to join the cast following the addition of Anne Hathaway as Selina Kyle (Catwoman's alter ego).
Gordon-Levitt will next be seen in Hesher, due out in April, and 50/50, which comes out in September.
The Dark Knight Rises is scheduled to hit theaters on July 20, 2012.
