The lineup of cast for the prequel version of the award-winning drama series Game of Thrones are been named, and the first to tap a slot on the cast list is two-time Oscar nominee Naomi Watts. It is said that Naomi will play a charismatic socialite hiding a dark secret. The character's name is however still under wraps to be unveiled soon, but a prominent role in the series is a sure guarantee for the actress. Joining the actress in the land of Westeros is Valley Girl actor, Josh Whitehouse, who will star opposite Naomi. The drama is set thousands of years before the events of the running Game of Thrones show. A logline from the network teased the plot without going into the specifics, "Only one thing is for sure: From the horrifying secrets of Westeros' history to the true origin of the White Walkers, the mysteries of the East to the Starks of legend-it's not the story we think we know." The pilot is based on a story from Jane Goldman and George R.R. Martin, with the teleplay credited to Goldman. Goldman will also serve as showrunner. In addition to Goldman and Martin, executive producers on the series include current Game of Thrones producer Vince Gerardis, as well as Damages and Bloodline co-creator Daniel Zelman and Jim Danger Gray. Chris Symes will serve as a co-EP.
