Game of Thrones Season 4 has added Pedro Pascal as Prince Oberyn Martell.
The Red Viper, as the character is called, is said to be the most anticipated new role for the upcoming season.
EW reported the news with a spoiler-free description:
Oberyn is a brash, charming, cunning prince of Dorne (part of the Seven Kingdoms of Westeros). His sister Elia was brutally murdered by the Lannister knight Gregor “The Mountain” Clegane when Mad King Aerys was overthrown by Robert Baratheon and the Lannisters. In season four, Oberyn comes to King’s Landing with revenge on his mind.
Game of Thrones returns to HBO in 2014 and will most likely be featured at this Summer's San Diego Comic-Con.
