Oh, hell.
I might have to break down and watch The Dark is Rising movie, regardless of the Americanization of the Stantons.
The parts of the Black Rider and Merriman Lyon have been cast.
Christopher Eccleston (swoon) and Ian McShane (having a hard time imagining Al Swearengen as Merlin, but I'm so totally willing to give it a go).
Thanks to La Fuse for the link.
