Ian McShane Game of Thrones

Game of Thrones Casts Ian McShane in Season 6 Mystery Role

Ian McShane is heading back to HBO with a small (but reportedly pivotal) role in Game of Thrones.

According to EW.com, which first broke the news, the Deadwood Emmy winner’s character will appear briefly in Season 6 as a character of “key importance.”

McShane will shoot his Game of Thrones cameo-of-sorts after he wraps his current one-season stint on Showtime’s Ray Donovan.

His GoT casting comes just days after HBO president Michael Lombardo essentially confirmed that the fantasy smash would conclude at the end of Season 8. “[The producers are] feeling like there’s probably two more years after six,” Lombardo added. “I would love for them to change their minds, but that’s what we’re looking at right now.”

Game of Thrones Season 6 is slated to premiere in April 2016.
