I could be mistaken, but beyond aside from Charles Dance (Tywin/Mountbatten), Rupert Vansittart (Royce/Cecil King) and Tobias Menzies (Edmure/Edinburgh), I’ve not seen any mention of this other former Game of Thrones cast members in season three of Netflix’s The Crown.

Who?

David Rintoul, the fire-raising ‘Mad’ King Aerys II himself, as Michael Adeane (The Queen’s Private Secretary):

Other GoT speaking role actors have appeared in previous seasons of The Crown and include Stephen Dillane (Stannis/as artist Graham Sutherland), Anton Lesser (Qyburn/as Harold Macmillan), Gemma Whelan (Yara/as Patricia Campbell). And whilst we’re talking about season three of The Crown, which cast member played the very same character 13 yeas ago?

Answer: Samuel West, who played Soviet spy Anthony Blunt in Cambridge Spies (2003) and now The Crown (2019):

Have you watched any of the third season of The Crown?
