Game Of Thrones Season 7: Everything We Know So Far

11. Jim Broadbent Is Playing An Archmaester

The biggest casting announcement we've had for Season 7 so far - and there's a good chance it'll stay that way now - is that of Jim Broadbent.

The Harry Potter and Only Fools and Horses alum was announced last year in a mysterious but "significant" role, at which time it was speculated by myself and many others that he'd be a Maester or Archmaester at the Citadel. Now that has been confirmed by Broadbent himself, who recently told ScreenCrush:

"I’m a Maester, an Archmaester. I’m an old professor character. I did five episodes. I did sort of one major scene in each episode.”

He also confirmed that he'll be appearing in Sam's storyline, which fits with his character description. The obvious (and most exciting) possibility is that he's playing Archmaester Marwyn, aka Marwyn the Mage, a book character Sam meets in Oldtown.

He could also be Archmaester Ebrose, a smaller character but one skilled in the arts of healing. Or, like with Ian McShane, he may be an amalgamation of both of these and more.
