Game of Thrones has cast a wealth of actors for season 3, but Dominic West isn’t one of them. What major role did the Wire actor turn down?

Speaking to The Huffington Post, West revealed that he was offered a substantial role, but turned it down because he didn’t know much about the show.

While he couldn’t recall what the character’s name was, he did say that, “it was a lovely part, a good part. I’m going to regret it.”

Considering that taking the job would have involved filming in Iceland for six months, the most likely possibility is that West was considered to play Mance Rayder, the King Beyond the Wall. This is also one of the only major characters in season 3 who has not yet been cast.
