The Winter King is a British historical fiction television series based on Bernard Cornwell's trilogy of novels The Warlord Chronicles,[1] starring Iain De Caestecker as Arthur Pendragon.

[3] The series acts as a retelling of the Arthurian legends and takes place in Post-Roman Dark Age Britain, where the warlord Arthur Pendragon has been banished while Saxons invade, and a child-king sits unprotected on the throne.

[13] The series was developed for television by Kate Brooke and Ed Whitmore, premiering in 2023[14] on ITVX, the upcoming streaming platform from U.K. broadcaster ITV.

[27] Local Bristol media reported on 30 September that parts of the Blaise Castle Estate in Henbury had been cordoned off as a filming location for this television drama.

The critics consensus reads: "Action-packed and sprawling in scope, The Winter King compensates for its lack of fidelity to Bernard Cornwell's books with sheer entertainment value.
