Here's a BTS look at the filming of 'Vikings: Valhalla' in Wicklow

The series wrapped back in January

Our first look at the 'Vikings' spin-off series has been released, teasing plenty of action and huge set pieces.

'Vikings: Valhalla' will be on its way to Netflix in the near future (finger's crossed for a 2021 release), but until then, we have this behind the scenes feature to drool over.

As you can see in the video below, the Wicklow wintery setting adds incredible depth to the tone of the series, and there are a number of big set pieces in store for us to see in the spin-off.

The series was filmed on location at Ashford Studios in Wicklow and wrapped production in January.

'Vikings: Valhalla' will pick up 100 years after the original series concluded, in the early 11th century. It will chronicle the legendary adventures of some of the most famous Vikings who ever lived – Leif Eriksson, Freydis Eriksdotter, Harald Hardrada and the Norman King William the Conqueror. These men and women will blaze a path as they fight for survival in the ever-changing and evolving Europe.

Included in the cast is Sam Corlett ('Chilling Adventures of Sabrina') as sailor Leif Eriksson; Frida Gustavsson (Swedish series 'Dröm') as Leif's sister Freydis; Leo Suter ('Beecham House') as Harald Sigurdsson, one of the last Viking Berserkers; Bradley Freegard ('Keeping Faith') as King Canute; Laura Berlin ('Breaking Even') as Emma of Normandy; Johannes Johannesson ('Cursed') as Olaf Haraldson; David Oakes ('Borgias') as Earl Godwin; along with Caroline Henderson, Pollyanna McIntosh, and Ashbjorn Krough Nissen.

The executive producers of the series are Michael Hirst ('Vikings', 'The Tudors'), Jeb Stuart ('The Fugitive', 'Die Hard') and Morgan O’Sullivan ('Vikings', 'Penny Dreadful'), and the series promises to be grittier than we've seen the 'Vikings' franchise yet.

Here's the behind the scenes tease. Expect more details to be released in the coming months.
