Kit Harington, Jon Snow in HBO's Game of Thrones, is trading one sword for another.
Heat Vision reports the 24-year-old actor has been cast as the future King Arthur in Warner Bros.' Arthur & Lancelot, joining The Killing's Joel Kinnaman in David Dobkin's take on the legendary heroes.
The film depicts Arthur as an illegitimate son raised by a poor knight in a village who'll grow up to be the ruler of England. Lancelot, on the other hand, is a rebellious noble with a distrust of government. Guinevere will play only a minor role in the film, but will be featured more prominently in potential sequels.
Harington, who also stars as the illegitimate son of a noble in Game of Thrones, will make his big-screen debut next year in Silent Hill: Revelation 3D.
