Fargo season three continues to add to its already impressive cast.

Harry Potter grad David Thewlis has booked a series regular role in the third season of the FX anthology, The Hollywood Reporter has confirmed.

As first reported by EW, Thewlis will portray V.M. Vargas, a mysterious loner and true capitalist who delivers Emmit Stussy (Ewan McGregor), the Parking Lot King of Minnesota, the bad news that he has just become partners with his employers, whose business interests lay outside the law.

McGregor will topline season three and play the dual roles of brothers Emmit and Ray Stussy in what will be his first series-regular role. The Leftovers' Carrie Coon is set as Gloria Burgle, a practical woman who is the chief of police in Edna Valley and a newly divorced mother. She struggles to understand this new world around her, where people connect more intimately with their phones than those directly in front of them. Mary Elizabeth Winstead will play Nikki Swango, a crafty and alluring recent parolee with a passion for competitive bridge playing. She is a woman with a plan who is focused on always being at least one move ahead of her opponents.

Season three of Noah Hawley's Fargo has been rumored to take place in 2010, following the events of the breakout drama's freshman season. It's unclear how or if it will tie into the events from the first run, though none of the stars from season one will return. Production on the third installment of Fargo is set to begin this year for a 2017 debut on FX.

Thewlis, who played Remus Lupin in the Harry Potter franchise, next appears in Wonder Woman. Fargo will mark his largest TV role to date. He is repped by CAA.
