The first promo for Fargo season three has been released showing a first look at its unrecognisable cast members Ewan McGregor and Mary Elizabeth Winstead.

A podgy long-haired McGregor can be seen in the 30-second teaser sat in a diner alongside Winstead's Nikki Swango - that is until the presence of Carrie Coon's Sheriff Gloria Bungle causes them to leave.

Details on the upcoming season of Noah Hawley's anthology series are scarce, but it's known that McGregor will play not one but two lead characters - namely brothers Emit and Ray Stussey.

“Emmit Stussy is the Parking Lot King of Minnesota. A handsome, self-made, real estate mogul and family man, Emmit sees himself as an American success story,“ reads the character description.

“His slightly younger brother, Ray Stussy, on the other hand, is more of a cautionary tale. Balding, pot-bellied, Ray is the kind of guy who peaked in high school. Now a parole officer, Ray has a huge chip on his shoulder about the hand he’s been dealt, and he blames his brother, Emmit, for his misfortunes.”

Season three will take place in 2010 - closer to the present than the first and second, the latter of which was a prequel.

David Thewlis, Michael Stuhlbarg, Scoot McNairy, Shea Whigham, Fred Melamed, and Hamish Linklater round out the cast.

FX's Emmy Award-winning Fargo has somehow defeated the odds by taking the Coen Brothers' modern classic and turning it into one of the best shows on TV.

Martin Freeman, Billy Bob Thornton, and Alison Tolman starred in the first season while season two saw a cast overhaul paving the way for Patrick Wilson, Ted Danson, and Kirsten Dunst.

Fargo season three will return in the US on 19 April with a UK release date set to follow soon after in the UK on Channel 4. Hawley;s other tV series, x-men spinoff Legion, is currently airing to rave reviews.
