Robert Duvall continues to sit in on James “Whitey” Bulger’s trial in Boston. The “Godfather” star, who played Corleone family lawyer Tom Hagen, has sat in on the notorious mob boss’s trial for racketeering and extortion previously and was back last weekend. Duvall was also seen at a New England Patriots practice. He’s shooting a film in Massachusetts with Robert Downey Jr., “The Judge,” in which Downey plays the son of a judge suspected of murder.
