Joseph Fiennes and Eva Green are going back in time to topline the Starz costume drama series “Camelot,” the first skein to come from Graham King’s GK-TV banner.

Fiennes will play the legendary wizard Merlin, while Green, in her first TV gig, will portray the sorceress Morgana. Brit thesps Jamie Campbell Bower and Tamsin Egerton have been cast as Arthur and Guinevere, respectively.

Lensing on the 10-episode tale of King Arthur and his comrades is set to begin later this month in Ireland. Series, written and exec produced by Brit TV vet Chris Chibnall, is targeted to preem early next year.

“Camelot” was the first series project greenlighted by Starz prexy Chris Albrecht after he moved to the pay cabler in January. It’s a prime example of the kind of multinational co-productions that Albrecht envisions as being key to Starz’s ability to secure high-end programming. GK-TV is co-producing “Camelot” with Irish production entity Octagon, Canada’s Take 5 Prods. and the U.K.’s Ecosse Films.

King launched GK-TV late last year with the aim of tapping his vast network of talent and financing connections to allow him the same kind of indie flexibility in production and distribution for the smallscreen as he enjoys in features.

Albrecht said the thesps on board for “Camelot” will “bring real passion and intensity to their roles.” King called it a “world-class cast,” and GK-TV prexy Craig Cegielski said the project would further the company’s “mandate of being the premier destination for cinematic-quality TV programming with a global appeal.”

Bower had a role in “New Moon” and will be seen in two upcoming “Harry Potter and the Deathly Hallows” pics. Egerton is known for her role the Brit comedy “St. Trinian’s” and its sequel.
