Comedy Central’s Key & Peele are crossing over genre lines to guest star in FX’s 'Fargo'. The hilarious pair will appear in four episodes of the TV adaptation, Variety reports. They will play FBI partners obsessed with finding Billy Bob Thornton’s rootless, manipulative Lorne Malvo. Eventually, their search lands them in Bemidji, Minnesota, and into the larger circle of the show. Their characters are named Pepper and Budge, so they may or may not have been written mostly as comic relief.

Fargo is an experimental FX production, adapted from the Coen brothers’ Oscar-winning film. Helmed by writer/exec producer Noah Hawley and exec producers Warren Littlefield, Joel & Ethan Coen, the film has been getting a lot of buzz over the past few months, as more exciting additions have been made to the cast.

Billy Bob Thornton
Billy Bob Thornton signed on to star in Fargo back in 2013.

Besides Thornton, Key and Peele, the cast also includes Breaking Bad’s Bob Odenkirk, as well as Martin Freeman, who signed onto the project in September 2013. With a cast like that, it sounds like the Coen brothers have a lot invested in the project, despite this being only a limited series. Filming is currently underway in Calgary, Alberta. Fargo is expected to air sometime this year, but the exact release date is still TBA.
