HBO's 'Game of Thrones' has yet to formally announce its Comic-Con 2013 plans, as we had previously expected the major season 4 cast to be revealed during the panel, but it seems the producers just couldn't wait to get the excitement going. Chilean actor Pedro Pascal will join the series in season 4, portraying the fan-favorite role of Prince Oberyn "The Red Viper" Martell!

Entertainment Weekly first broke the news, adding that the actor was previously featured on CBS drama 'The Good Wife,' ABC’s now-canceled 'Red Widow' and USA newcomer 'Graceland.' For those understandably unfamiliar with the character (minor spoilers), the Dorne prince will arrive in Kings' Landing in season 4 with vengeance on his mind, specifically against Lannister knight Gregor “The Mountain” Clegane for killing his sister Elia during the overthrow of Mad King Aerys that predated the series.

Said executive producers David Benioff and Dan Weiss of the casting:

This was a tough one. The Red Viper is sexy and charming, yet believably dangerous; intensely likable, yet driven by hate. The boys love him, the girls love him, and he loves them all back. Unless your last name is Lannister. We found a fellow who can handle the job description and make it seem effortless. He wasn’t easy to find and he won’t be easy to stop.

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.

HBO will likely reveal much more at this year's Comic-Con panel, but in the meantime, what say you? Are you excited to see The Red Viper make his way through 'Game of Thrones' season 4? Will Pedro Pascal prove up to the task?
