Trivia

 * The casting call describes him as "a good and just ruler who, beneath the surface, is a master manipulator who can carry a grudge to the grave, and maybe beyond. He harbors an eternal burning love for Guinevere that can lean toward being a bit... controlling. For this role, Once aims to cast a gent in his mid-30s to early 40s, and again a British accent is mandatory".
