During an August 2025 interview with Entertainment Weekly, Dillon, who co-created the show and plays the role of detective Ian Ferguson, candidly spoke about the forthcoming season of 'Mayor of Kingstown' and described it as "a detonation, not an escalation." Then, Dillon further added, "The blade’s sharper. The cuts go deeper. It’s about the intricacies of human emotion under pressure, and the choices we make when we have no good choices left. It's an incendiary season 4." The fourth season of 'Mayor of Kingstown' is set to premiere on Paramount+ only on October 26, 2025..
