HBO’s “Game of Thrones” doesn’t return for its third season until March 31, but a new round of photos reveals what’s in store for the denizens of Westeros — and offers an early look at some of the newest additions to the already expansive cast.
Chief among the new characters joining the lineup is Ciaran Hinds as King Beyond the Wall Mance Rayder, with other new faces including Diana Rigg as Lady Olenna Redwyne, otherwise known as the Queen of Thorns, who’s best described as the Dowager Countess of Westeros.
Rigg, of course, remains a beloved figure for her turn as Emma Peel on the BBC TV series “The Avengers.”
The third season of “Game of Thrones” will be based on the first half of “A Storm of Swords,” the third book in George R.R. Martin’s “A Song of Ice and Fire” series and one of the longest in the series to date (in hardcover, it’s 973 pages).
Martin created a stir last year when he told audiences at San Diego’s Comic-Con International, “I may have to start killing some of these characters to make room for new ones.”
Among the other new cast members joining the show this season: Mackenzie Crook (from the British iteration of “The Office” and the “Pirates of the Caribbean” movies) as Orell, Clive Russell as Brynden “The Blackfish” Tully, Kerry Ingram as Shireen Baratheon, Richard Dormer as Beric Dondarrion, Ellie Kendrick as Meera Reed, Thomas Brodie-Sangster as Jojen Reed and Paul Kaye as Thoros of Myr.
