Naomi Ackie, Denise Gough, Jamie Campbell Bower, Sheila Atim, Ivanno Jeremiah, Georgie Henley, Alex Sharp, and Toby Regbo have all joined the pilot for HBO's "Game of Thrones" prequel in series regular roles, according to Variety.

Previously announced cast members for the prequel include Naomi Watts and Josh Whitehouse, though no role descriptions have been announced.

In addition, SJ Clarkson has also signed on to direct the pilot and to serve as an executive producer. Clarkson was recently chose to direct the next "Star Trek" film and she recently executive produced and directed the limited series "Collateral" for BBC and Netflix.

Taking place thousands of years before the events of "Game of Thrones," the new show chronicles the world's descent from the golden Age of Heroes into its darkest hour. And 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 series was co-created by Jane Goldman and George R.R. Martin. The story was written by Goldman and Martin with Goldman writing the teleplay. She will also serve as showrunner. She and Martin will executive produce along with Clarkson, Daniel Zelman, James Farrell, Jim Danger Gray, and "Game of Thrones" executive producer Vince Gerardis. Chris Symes will co-executive produce.
