Ian McShane is joining Game of Thrones, HBO confirmed Saturday morning. The Deadwood alum is returning to the network for the hit fantasy series' sixth season. Who exactly the British actor will play in the drama is shrouded in secrecy. In previous years, HBO typically had announced numerous cast members by this time, but McShane is the first name to be confirmed for the upcoming season. Season six is is the most mysterious one yet, as the show has largely caught up with the five books George R. R. Martin has published so far in his A Song of Ice and Fire series. McShane, known for portraying bad guys, scoundrels and thieves on-screen, is currently guesting in the third season of Ray Donovan. On Thursday, HBO programming president Michael Lombardo revealed the network was eyeing at least eight seasons for Game of Thrones.
