Here’s Who Jim Broadbent Is (Probably) Playing onGame of Thrones

As Game of Thrones fans grow ever - impatient for HBO to reveal the date of the season seven premiere , any tidbit pertaining to the upcoming sequence becomes big intelligence . Today ’s nugget come good manners of new cast member and stager player Jim Broadbent , who revealed a bit about the part he ’ll be playing — and we have a good guess of who it is .

Of course , under penalty of beheading by an elaborate sword of Valyrian steel , the Oscar winner could n’t bring out much . Here ’s what he toldScreenCrush :

I ’m a maester , an archmaester . I ’m an older prof theatrical role .

He also said : 1 ) his character has “ sort of one major shot ” in five of the time of year ’s seven episodes ; 2 ) his character appears in scene with Sam Tarly ; and 3 ) he did all of his filming in a Belfast studio apartment , and was n’t involve with in any CG special effects or localisation shooting .

So — as ScreenCrush deduced , and we have to concord , Broadbent is probably playing Citadel resident Maester Marwyn , also sleep with asMarwyn the Mage . In the al-Qur’an , Marwyn is mentioned as being an expert in human anatomy ( he trained the crone Mirri Maz Duur in it ) and the only maester who believe in ghosts and Dragon . In A Feast for Crows , he learn about Daenerys Targaryn and her dragons from Sam , and then quickly set canvas to conform to her .

Of of course , if this is the quality Broadbent is playing , his role could change importantly from the book — but it ’s cagy cast , and given Broadbent ’s antecedently - seen power to bring a intermixture of dignity and goofiness to supernatural chronicle ( Harry Potter and the Half - Blood Prince , The Chronicles of Narnia , etc . ) , it sound like a perfect paroxysm .
