TVLine Items: Once Crowns King, HBO Casts MLK Jr., Rick and Morty and More

Liam Garrigan Once Upon a Time

Knights of the Round Table, meet your king.

Once Upon a Time has cast British actor Liam Garrigan (24: Live Another Day) as King Arthur, per EW.com, who as TVLine first reported will heavily recur during the first half of the ABC series’ fifth season.

King Arthur is described 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 the yet-to-be-cast Guinevere that can lean toward being a bit controlling.

Garrigan’s TV credits also include Strike Back and The Pillars of the Earth. He will begin his Once reign in the Season 5 premiere, airing Sunday, Sept. 27, at 8/7c.
