Chris Rock is moving to Fargo. The comedian will star in season four of FX’s hit limited series Fargo, the network announced Friday at the Television Critics Assn. press tour. The critically acclaimed series will begin production next year, for a targeted air date next year as well. Described as a story of “immigration and assimilation and the things we do for money,” season 4 of Fargo is set in 1950 in Kansas City, Missouri, where two criminal syndicates — one Italian, one African-American — have struck an uneasy peace. To cement their peace, the heads of both families have traded their eldest sons. Rock will play the head of one of the syndicates, who has surrendered his son to his enemy, and who must raise his son’s enemy as his own. But then the head of the Kansas City mafia goes into the hospital for routine surgery and dies — and everything changes. Noah Hawley, who created the award-winning series, will again return as showrunner, writer and director. Joel & Ethan Coen, Warren Littlefield and John Cameron have also served as executive producers. Fargo is produced by MGM Television and FXProductions.
