The dust has settled, the screams have quietened down, and season 5 of Game of Thrones is fading a little into the past. What matters now is the future. Production is underway on the sixth season of the show, which is now well past the halfway mark and will surely be looking to ramp things up heading towards the ultimate endgame. With the actors coming back, a lot of the focus has been on whether you-know-who (no, not Voldemort, but sorry for saying the name) is coming back, surrounding a lot of chatter about the actor being spotted and set and whether or not they've had a haircut.

He is one of the bigger names the show has cast, and suitably it has been confirmed that he'll have an important role. EW, who broke the news, describe the actor has having "a relatively small amount of screen-time during the season, yet his character is of key importance."
