And another casting has now been revealed by James Hibberd of EW (who scores a hat-trick, with three casting announcement scoops in one day)!

Joining Carice van Houten, Stephen Dillane, and Oliver Ford Davies is actor Liam Cunningham, late of Starz’s now-cancelled Camelot. This, paired with Dillane having been in the film King Arthur (in the role of Merlin), suggests Camelot actor Clive Standen was absolutely on the mark when he said a Camelot actor and another one who’d been in some other Arthurian production were being cast.

Cunningham, an Irish actor and veteran of stage and screen, has been involved in a number of genre productions besides Camelot; including Dog Soldiers, the remake of Clash of the Titans, and Centurion.
