Mayor of Kingstown is losing one legendary actor ahead of season 3. The crime drama, co-created by Taylor Sheridan and Hugh Dillon, is led by Jeremy Renner. It takes place in the titular town, where the business is an incarceration. It's the domain of the McLusky family, who act as the mediators between the street gangs, prisoners, guards, and cops. The show has been a hit for Paramount+, gaining speedy renewals, but going into season 3, the show will lose a key character.
