The Winter King: Cast announced for new ITV drama

Casting has been announced for new ITV drama The Winter King, based on Bernard Cornwell’s Warlord Chronicles.


A bold and revisionist take on the well-loved Arthurian Legends, The Winter King follows Arthur Pendragon as he evolves from outcast to legendary warrior and leader.

The Winter King is set in the 5th century long before Britain was united. In a land of warring factions and tribes when the World was brutal and lives were often fleeting.

Featuring an exciting range of established names and new talent the cast includes:

Iain De Caestecker (The Control Room, Agents of S.H.I.E.L.D) as a young Arthur, who begins as an exiled bastard before becoming the greatest hope for Britain.

Stuart Campbell (SAS Rogue Heroes, Clique) is Derfel who transforms from left-for-dead orphan to the truest of all warlords.

Ellie James (Giri/Haji, I May Destroy You) is Nimue a priestess saved by Merlin because she can see the gods – he gives her power, wisdom and learning.


Eddie Marsan (The Thief, His Wife and The Canoe, Deceit) is Uther, High King of all Dumnonia, old and battle tested. He commands incredible authority, over almost all, bar Merlin.

Valene Kane (The Fall, Gangs of London) is Morgan, Arthur’s half-sister and another bastard child of King Uther. She is a sharp-tongued and independent minded pagan and student of Merlin.

Simon Merrells (Good Omens, Knightfall) is Gundleus, King of rival kingdom Siluria. Imposing and savage, Gundleus is prepared to slaughter whoever he needs to secure power.

Jordan Alexandra (Mammals) as Guinevere, the exacting, beautiful and ambitious exiled-Princess of Henis Wyren;

Steven Elder (The King, A Spy Among Friends) as Bishop Bedwin, the deeply kind and affable Bishop of Dumnonia;
