Ian McShane Joining Season 6 of 'Game of Thrones'? Spoilers, Release Date, Cast, Plot & Rumors Here!

Another actor is joining the "Game of Thrones" cast for the hit TV series' sixth season. And he's none other than "Deadwood's" Ian McShane.

With his inclusion in the HBO series, will there be more spoilers leaking out from the already busy rumor mill?

Before going to that bit, some background info about the British actor for those not in the know.

McShane has been called by Forbes as "one of HBO's best alumni," which makes his GOT casting a wise move.

"McShane's portrayal of Al Swearengen in Deadwood remains one of the best characters to ever appear in an HBO show, and GoT showrunners were smart to hire him back for a new role," Forbes' Paul Tassi noted.

"McShane launched to American TV stardom by playing a mesmerizingly homicidal frontier kingpin Al Swearengen on 'Deadwood,' then had roles in films 'Kung Fu Panda,' 'Sexy Beast,' 'Pirates of the Caribbean: On Stranger Tides,' 'John Wick' and many others," Entertainment Weekly said. "His most recent regular TV gig was an arc on Showtime's 'Ray Donovan'."

EW also noted that the actor would easily fit in GOT's "lawless world and chewing on the show's Emmy-nominated dialogue."

Considering his past roles, will McShane be playing a villain on GOT?

While this speculation has not yet been confirmed, EW said that although McShane has a rather small role on the show, it's an important one. No other details have been revealed yet as the series is tight-lipped about his character.

"'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)," EW said.

Can you make a guess on McShane's character? Doing that proves to be a real challenge as even those who have read the books won't be able to figure it out, considering Martin has not yet revealed the narrative in which McShane's character appears. In short, his character is in a part of the book that has not been released yet.

"I hope he plays Bran Stark From the Future who comes back in time somehow to save the Stark family but accidentally picks the wrong year. It'd be a twist no one would ever see coming," Kotaku's Phil Hornshaw speculated.

Meanwhile, Forbes' Tassi suspects that, considering McShane's appearance and mood in his previous roles, he might play Lord Randyll Tarly.

"Randyll Tarly is Sam Tarly's father, the one who sent him to the Night's Watch or said that he would see him 'accidentally' killed while hunting," Tassi explained. "Tarly has never made an appearance in the show, but he's cropped up a bit in the books."

Tassi also speculated he might play Victarion or Euron Greyjoy, a Dothraki Lord, or a completely new character.
