And again, clues from George R.R. Martin for two more roles, this time for named characters:
“The first guy loves goats, the second likes his meat tough. The second guy never conquered India. Is it rabbit or rarebit? The first guy might know. The guy who had more dingers than anyone but the guys who liked the juice, well, the second guy isn’t that guy, or even the guy who chased that guy all summer. The first guy has been a nobleman, a moron, and a hog. The second guy holds a record: the biggest little guy. The first guy has been every flavor of cop. The king of the deep knocked the second guy topsy turvy.”
The first actor is clearly cast as Shagga son of Dolf. The second, we guess, is cast in the role of the Greatjon, one of the Stark’s more memorable bannermen.
