Actor Bobby Cannavale has joined the cast of HBO's Boardwalk Empire, as a series regular in Season 3.

Bobby Cannavale will play Gyp Rosetti, a charming gangster who poses as a threat to Steve Buscemi's Nucky Thompson. We reported back in October that HBO renewed Boardwalk Empire for Season 3, just days after Season 2 premiered.

Boardwalk Empire, created by The Sopranos writer Terence Winter, stars Steve Buscemi, Michael Pitt, Kelly Macdonald, Michael Shannon, Shea Whigham, Aleksa Palladino, Michael Stuhlbarg, Stephen Graham, Vincent Piazza, Paz de la Huerta, Michael K. Williams, Anthony Laciura, Paul Sparks, and Dabney Coleman.

It isn't known when production will start on Boardwalk Empire Season 3, although it will likely premiere sometime this fall.
