According to Deadline, the untitled project is a dark comedy based on "Hellfjord," a TV series Wirkola created, wrote and produced in his native Norway with Kjetil Omberg, Terje Strømstad and Stig Frode Henriksen. The seven-part "Hellfjord" screened at Fantastic Fest last year, where programmer Todd Brown described it as falling "into the sweet spot between 'Hot Fuzz' and 'Twin Peaks.'"
The Norwegian series follows an Oslo police sergeant (played by Ali) who after an unfortunate incident involving a horse and a parade is sent to the remote town of Hellfjord to serve as district sheriff for the minimum amount of time until he can be legally fired.
Wirkola will script the Showtime adaptation alongside Henriksen and Zahid Ali, who both also served as writers on the original series. Wirkola will executive produce the project with Ferrell and McKay, and will direct the pilot if one is ordered -- Deadline says there are no plans for Ali and Henriksen, the original's stars, to act in the Showtime version. Take a look at the (unsubtitled) first episode of "Hellfjord" below.
