The Winter King takes viewers to the 5th century Dark Ages depicting the tale of an exiled Arthur Pendragon

Earlier this month, Sony Pictures Television dropped the official trailer for The Winter King giving an insight into what to expect from the time-old tale of Britain's King Arthur.

The 10-part historical drama is set in the Dark Ages during the 5th century and centers around the valiant Arthur Pendragon (Caestecker), the bastard son of ruthless King Uther (Marsan), who has been exiled. As an outcast, Arthur grows into a formidable warrior and respected leader, trying to find his place in the world.

However, Britain is split up into several tribes and groups which cause obstacles on Arthur's path. Sometimes, conflicts turn violent and hostile. Elsewhere, there also exist the Saxon invader threats and Druid-Christian tensions.

The official synopsis for the series, as per TV Line, states:

"The Winter King is set in the fifth century, long before Britain was united, in a brutal land of warring factions and tribes, where lives were often fleeting. The series follows Arthur Pendragon as he evolves from outcast to legendary warrior and leader."

According to The Wrap, head of MGM+ Michael Wright commented on the upcoming series in an official release:

"The Winter King is a cinematic and imaginative reinterpretation of the Arthurian legend. Kate Brooke, Ed Whitmore, and the magnificent cast take viewers on a fascinating and entertaining journey through this timeless tale told through a new lens."

The same outlet reported that executive producer Julie Gardner further added:

"It’s long been Bad Wolf’s ambition to bring the Arthurian legend to the screen. It’s a story of courage, sacrifice and passion that has endured for generations. With Bernard Cornwell’s trilogy as our North Star, we are honored to be on this quest with our wonderful partners at MGM+, ITVX and Sony Pictures Television."
