AceShowbiz - Warning! This article contains SPOILERS for Mayor of Kingstown season 4, episode 2.
In a series grappling with crime and injustice, Mayor of Kingstown has always featured formidable antagonists. However, the arrival of Lennie James as the new mob boss, Frank Moses, is already causing significant commotion. Four seasons in, Taylor Sheridan’s intense crime drama introduces James’ character, who in just two episodes, has swiftly asserted himself, promising a villain unlike any seen before.
Lennie James brings a formidable acting pedigree to the role of Frank Moses. Widely recognized for his breakout performance as DCI Tony Gates in 2012's Line of Duty, he later gained extensive notoriety playing Morgan Jones across The Walking Dead universe. This background perfectly suits him to embody the menacing and complex presence of Moses.
Mayor of Kingstown previously showcased memorable villains like Milo Sunter (played by Aidan Gillen), a truly monstrous figure whose obsession with Mike McLusky led to horrific acts, including the bombing that killed Mike’s mother. Later, Konstantin emerged, presenting a different but equally brutal threat, notably abandoning a helpless baby after murdering its mother. Both were undeniably awful, posing intense threats to Mike McLusky and Iris.
Yet, the chilling potential of Frank Moses seems to eclipse these past horrors. Moses is introduced as an old-school mob boss hailing from Detroit, one who has refined his criminal operation into a sophisticated, well-oiled machine. His calculated ruthlessness and strategic approach suggest a deeper, more profound challenge to Mike McLusky’s tenuous hold on order, redefining the criminal landscape of Kingstown.
Frank Moses makes an unforgettable entrance in the premiere of Mayor of Kingstown season 4. He is first seen standing over victims tied to a train track, swiftly executing numerous Russians before vanishing without a trace. By episode 2, Moses begins establishing his influence, introducing himself to Bunny, the leader of the Crips, and eventually meeting Mike McLusky. His formidable reputation precedes him; both Mike and his secretary, Rebecca, are keenly aware of his notorious activities. Moses’ presence is both magnetic and intimidating, leaving a lasting impression and hinting at the vast, intricate web of power he intends to weave across the city.
