The Winter King – Cast Confirmed

In a press release ITVX have confirmed some of the cast already rumoured for the upcoming adaption of 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.
