It’s game on for Pedro Pascal…

The Chilean actor has been cast in HBO’s drama Game of Thrones in one of the series’ most anticipated new roles of the upcoming fourth season.

Pascal will portray Prince Oberyn Martell, who is called the Red Viper. Martell, The Prince of Dorne comes to Kings Landing seeking revenge for the death of his sister, who was killed by the Lannisters when the Mad King was overthrown.

Pascal, who has been cast in a guest starring role on Showtime’s Homeland, has previously had arcs on CBS’ The Good Wife, ABC’s Red Widow and USA’s Graceland.

Game of Thrones showrunners David Benioff and Dan Weiss told Entertainment Weekly the casting was “tough,” saying, “The Red Viper is sexy and charming, yet believably dangerous; intensely likable, yet driven by hate… 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.”

The hit HBO drama returns in 2014.
