Ian McShane is fantastic in everything! This is known. HBO recognized this many moons ago when he was cast in their criminally under-seen 'Deadwood' and Mr. McShane will be returning to HBO for the sixth season of 'Game of Thrones'.
This story broke with Entertainment Weekly who learned little more than McShane being involved in the upcoming season. Their report says that he will have little screen time but still plays a key character that will affect the season greatly. Now that the series has reached areas that even book-readers are unfamiliar, I won't even start speculating as to who he could be playing.
While HBO has been tight-lipped on the upcoming season, we will learn more in the coming months in the way of more casting announcements and trailers probably starting in early winter. HBO has done well with casting many unfamiliar actors for this series but also hasn't stayed away from bigger names. Casting news like this only increases my already massive anticipation for this upcoming season and I can't wait to see how it plays out. Check back here for more information as it is available.
