Bernard Cornwell Talks The Winter King

One of the first guests in the upcoming The Winter King Podcast is author Bernard Cornwell.

The Winter King is the first novel in Cornwell’s Warlord Chronicles, first published in the UK in 1995 and now turned into a TV series starring Iain De Caestecker, Jordan Alexandra, Stuart Campbell and Ellie James. The book is based on characters and plot elements from Arthurian myth, but considerably changed and re-worked.

Despite favourable reviews from critics, the TV series faced some backlash online due to its diverse cast and lose adaption of the original source material. Bernard Cornwell has now addressed some of the concerns in the Official The Winter King Podcast (available on all podcast platforms):

I think they did a magnificent job, a quite extraordinary job, so I think you’re in for a treat.

I mean, I think the casting has been superb. The one member of the cast who actually dazzled me was Ellie James playing Nimue, which was almost exactly as I’d in a sense imagined Nimue.

So obviously when you get a character on screen, who’s doing exactly what you put her in to do in the book, you like it. She has a force which is remarkable and she’s a formidable young woman, Nimue, and she has a great role to play in the rest of the series of course.

Not always as a heroine but she’s a very complicated lady, is Nimue, and Ellie James I think caught her superbly, perfectly in fact, and I think the casting has been superb all through and Iain [de Caestecker] makes a wonderful Arthur.

The Winter King – Who is in the Cast?

As filming for the new ITV series The Winter King based on the Warlord Chronicles by best-selling author Bernard Cornwell (The Last Kingdom) is well under way, fans are eager to learn who will be in the cast.

The story is a retelling of the Arthurian legend and takes place in Post-Roman Dark Age Britain, a land where the warlord Arthur has been banished and Merlin has disappeared,Saxons are invading and a child-king sits unprotected on the throne. We meet a vain and unpopular Lancelot, an ambitious and scheming Guinevere, a Merlin who is more absent Druid than mystic magician, and a Mordred who is Uther’s grandson and legitimate heir. The tale is told by the Saxon-born monk Derfel Cadarn for Igraine, a young queen.

So far there have been no official statements from the production itself but we were able to gather some information about some of the main cast.

Iain is a Scottish actor known for playing Leo Fitz in Marvel’s Agents of S.H.I.E.L.D.


Jordan Alexandra plays Arthur’s wife Guinevere, an ambitious woman who cares very little for others and seems only to want power and a high social status.

Stuart Campbell plays Derfel Cadarn, the narrator of the story. He is a warrior and loyal to Arthur. Even though he sees Arthur’s flaws, he recognizes greatness and knows that Arthur is the only hope for Britain.

Andrew of course needs no further introduction on this page. 😉


Valene Kane was also cast in the series but her character is not yet known. Speculation sees her maybe as Nimue, a druid priestess and Merlin’s lover. She’s also a first love to Derfel and his life long friend.

Valene is from Northern Ireland and can be seen in The Fall and Gangs of London.


Welsh actor Steve Ryan is also confirmed to be starring in the series but it is not yet known which character he will play.

The Winter King – Filming locations

So far there is not much information on The Winter King, the new series that Andrew Gower is currently filming as a series regular playing a chararcter named Sansum. We tried to compile as much as we could find out about the different filming locations in the article below:

Portraying a revisionist take on the well-loved Arthurian legends, the series follows Arthur Pendragon as he evolves from outcast son 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.

The Bristol Post reported about film sets in the West Country and around Bristol for the upcoming series, including “mocked-up medieval villages and forts” in Patchway and Blaise Castle Estate.

Plans for a temporary film set off Highwood Lane in Patchway Trading Estate, which will be used between July 2022 and January 2023, were submitted to the South Gloucestershire Council.

The units primary purpose is to provide a space for the construction of both interior and exterior ‘sets’ which the series requires. In addition to these temporary set structures, the site will provide space for the supporting infrastructure, cast, crew and logistical vehicles required to facilitate the filming of the show.
Due to the nature of the film making process, the level of activity at the site will vary across the period this planning application pertains to. After an initial construction phase, the filming operation itself – including cast and crew, will vary between 70 and 150 persons to span across circa 70 days between July 2022 and January 2023. As a result, it is not foreseen that the activity at this site will impact the local community in an adverse way.

The exterior sets include a ‘fortified encampment’ and ‘mountainous ravine’ appropriate to Arthurian Britain – the time period in which the series is set.

Blaise Castle Estate seems to be another major filming site being transformed into a medieval village. The grade II-listed parkland will host thatched dwellings of wood, wattle and daub covering almost 30,000 sqm. Two film sets will be built on the estate: a cluster of houses and animal pens amongst trees adjacent to woodland, named on plans as “Avalon Village”, plus a wooden tower with a “scaffold plinth” and “scaffold birdcage”.

Tropiquaria was also used as a base filming took place within around a five-mile radius of the Watchet wildlife park and aquarium.

The Swindon Advertiser also reported about film crews being spotted near Bradford on Avon in the Iford Valley below Iford Manor Gardens.

They used the Iford Cider premises on the road to Freshford as a film base and were in the area for two nights […]. It is understood that horses were involved and some of the actors were seen wearing loincloths and other period costumes.

It does need to be pointed out that the cast mentioned in the article is the one for the upcoming Dungeons & Dragons: Honor Among Thieves that was also partly shot in the area according to the Somerset County Gazette. The cast for The Winter King – other than Andrew Gower – has yet to be revealed.

The Winter King will debut in the UK on ITV’s new streaming platform ITVX (Source: Variety), possibly in late 2023 / early 2024.
