Game of Thrones still holds many mysteries waiting in its final two seasons, and not just because George R.R. Martin's novels can't possibly catch up with their TV counterpart now. In recent years, HBO's grip on spoilers has continually tightened, leaving us entering new seasons with few plot cues and, often, cast members announced without accompanying character names.
One such new addition for Season 7 is Jim Broadbent, best known to genre fans for his work as Professor Horace Slughorn in Harry Potter and the Half-Blood Prince. We've known about Broadbent's involvement in Game of Thrones since last summer, but his role has yet to be revealed. Speaking with ScreenCrush about his time on the show, Broadbent did give us a big clue.
"I'm a maester, an archmaester," Broadbent said. "I'm an old professor character."
This revelation, plus Broadbent's comments that he shot all of his scenes on a Belfast set with actor John Bradley (who plays Samwell Tarley) clearly place him in Oldtown, where Sam arrived at the end of last season to begin his studies to become maester for the Night's Watch.
Now, we can't be sure, but Broadbent's stature, and the fact that he shot five episodes for the new season, points to him playing Archmaester Marwyn. Marwyn is a bit of a maverick among the other maesters, spending his time in the seedier areas of Oldtown and holding many beliefs that the other maesters might dismiss. In A Feast for Crows, he tells Sam that the other maesters will not believe that dragons have returned to the world, and he immediately has a strong connection to the rise of Daenerys Targaryen.
Again, we don't yet know if Marwyn is Broadbent's character, but it would make sense, and that kind of role could lead to Broadbent returning for the final season next year.
Game of Thrones returns this summer. What do you think? Is Broadbent this pivotal archmaester?
