Richard Dormer has been roped in to star in The Watch, a BBC America series based on stories from Terry Pratchett's Discworld books. Dormer, best known for playing Beric Dondarrion in Game of Thrones, will feature as Sam Vimes, the captain of a band of misfit cops known as The Watch. Set in the fictional city of Ankh-Morpork, where crime is legal, the show is being touted as an "anarchic drama". Game Of Thrones’ Second Prequel May Be a Spin-Off Based on House Targaryen, Should We Expect More Dragons?

"I'm so thrilled to be part of this brilliant madness and mayhem. I was immediately drawn to the multitude of layers to Sam Vimes, and I find the dynamic between him and his band of disenfranchised comrades very compelling," Dormer said in a statement. The show will revolve around the group as it rises up from decades of helplessness to save their corrupt city from catastrophe. Game of Thrones Actor James Cosmo in Dhanush’s Next!
