'Game of Thrones' season 4 remains a good while off, but as with the previous season, fans are eager to learn who will take the roles of revered George R.R. Martin characters when HBO finally introduces them into their own adaptation. We've heard quite a bit about several new Dornish characters to date, but are you ready to meet the oft-mentioned Mace Tyrell? Introducing Roger Ashton-Griffiths!

Series creator George R.R. Martin himself first teased the casting over his blog, yesterday providing hints that a certain "wedding guest" who was both a father and a son had been cast, filled by an actor who had been "a bishop, a cardinal, a prior, a friar, a vicar, a knight, a lord, a mayor, a director." Naturally, 'Game of Thrones' fans quickly unearthed the name of Roger Ashton-Griffiths, whose past acting credits fit all those roles, before Martin confirmed their findings.

For those unfamiliar with the character, Mace Tyrell is known to fans of George R.R. Martin's books as father to Margaery and Loras, and son to the sharp-tongued Lady Olenna (Dame Diana Rigg). Tyrell has been mentioned multiple times on the series, and in fact had been introduced in Martin's second novel "A Clash of Kings," though HBO opted to reserve his more important appearances for Margaery and Joffrey's wedding until now.

To date, HBO has cast in the more important roles of 'Game of Thrones' season 4 Pedro Pascal as Prince Oberyn "The Red Viper" Martell, Indira Varma as his lover Ellaria Sand, and 'Sherlock' star/writer Mark Gatiss in an unknown role, previously speculated to be none other than Mace Tyrell.

Outside of those familiar with George R.R. Martin’s books, relatively little is known of ‘Game of Thrones’ season 4, though we recently learned that previous season characters Lysa Arryn (Kate Dickie), Ser Alliser Thorne (Owen Teale), Rorge (Andy Beckwith) and Janos Slynt (Dominic Carter) would all return, among others. We recently saw the full list of writers and directors for the 2014 season emerge, revealing that season 2 “Blackwater” helmer Neil Marshall will return for the always-pivotal ninth episode.
