Though we've no doubt 'Game of Thrones' season 4 will prove every bit of a major ratings splash as its predecessors, even fans of George R.R. Martin's writing have a difficult time imagining how it will splice together aspects of multiple novels for the increasingly spread-out cast. At least one major character may move significantly further in their story, however, as UK actor Struan Rodger has seemingly joined season 4 in a likely crucial role.

Via Zap2It, we've learned that Rodger has among his online resume the 'Game of Thrones' role of the "Three-Eyed Raven," which as of season 3 had only appeared in its avian form in Bran Stark's (Isaac Hempstead) dreams. Speculation suggests that Rodger's personification of the "Three-Eyed Raven" may actually suggest that the character will emerge as Lord Brynden Rivers, better known as Bloodraven, near the end of Bran's overall arc.

The character doesn't technically appear until Martin's fifth novel, "A Dance With Dragons," which could suggest that we see Rodger's figure only in dreams until the latter half of season 4, returning for a more prominent role in season 5.

While we wait for ‘Game of Thrones’ season 4, HBO has cast in known roles Joel Fry as Hizdahr zo Loraq, Roger Ashton-Griffiths as Mace Tyrell, Pedro Pascal as Prince Oberyn Martell, Indira Varma as Oberyn’s lover Ellaria Sand, and ‘Sherlock’ star Mark Gatiss as Tycho Nestoris. ‘Banshee‘ star Joseph Gatt will appear in a role speculated to be that of Wildling chieftan Styr, Magnar of Thenn, while ‘Treme”s Michiel Huisman will replace Ed Skrein as Daario Naharis, and Hafthor Julius Bjornsson will take over the role of Gregor “The Mountain” Clegane from Ian Whyte, among other recastings. Previous season characters Lysa Arryn (Kate Dickie), Ser Alliser Thorne (Owen Teale), Rorge (Andy Beckwith) and Janos Slynt (Dominic Carter) will likely all return.

We'll keep an ear out for the latest 'Game of Thrones' casting news, but what say you? Are you interested to see how season 4 balances between multiple novels, or has the HBO adaptation bitten off more than it can chew?
