There should have been some casting news already from Game of Thrones at Comic-Con, but that never happened. I guess the wait is worth it since Ian McShane (Deadwood, Pirates of the Caribbean: On Stranger Tides) has joined the cast for Season 6. It’s a mystery right now on who he’s playing but have some speculated on whether or not he will be Randyll Tarly (Sam’s Father) or Euron Greyjoy (Theon’s Uncle). Or maybe he will be someone different, perhaps in a flashback sequence? Either way, McShane is a great addition to the cast!
The show’s tight-lipped production will not reveal any details about McShane’s character, who’s coming on board for the most mysterious season yet. Thrones is preparing to dive headlong into narrative territory not yet revealed in author George R.R. Martin’s novels (and despite that opening sentence, McShane’s character could theoretically appear in Westeros or Essos or somewhere in between).
We can tell you, however, that sources say McShane has a relatively small amount of screen-time during the season, yet his character is of key importance.
