Called 'Death and Nightingales', it's a three-part adaptation of the 1992 Eugene McCabe novel of the same name which takes place in 1885 over a 24-hour period in Fermanagh, Ireland.
Dornan, a native of Co. Down, stars alongside Dublin native Ann Skelly, who you may recognise as Red Rock's Rachel Reid, as well as Matthew Rhys, star of hit US show The Americans.
The story is a star-crossed lovers sort of affair which follows Beth Winters (Skelly) who decides to run away with her lover Liam (Dornan) on her 23rd birthday but risks defying her domineering stepfather Billy (Rhys).
Take a look at them in action in the first official images from the show:
Dornan said earlier in the year about his new role: "I'm thrilled to be reunited with Allan and his brilliant scripts to play such an intriguing character like Liam Ward and to return to Northern Ireland and BBC Two."
While Skelly says: "Playing such a strong character as Beth Winters is truly an actor’s dream, and a fantastically intense challenge to be given the opportunity to play. And to get to work with such brilliant actors like Matthew and Jamie, and a director like Allan Cubitt, is just surreal to me. I can’t wait to start!"
Filming for 'Death and Nightingales' began this summer, and it's expected to air later this year on BBC Two.
