Sylvester Stallone turns to 4MK, locking crime plans

Sylvester Stallone is already deep in a crime universe with Tulsa King, but the next chapter is lining up fast—and it looks like it’s headed for even darker territory.
Stallone leads as Dwight “The General” Manfredi in the Taylor Sheridan crime saga Tulsa King. The series has aired three full seasons, and a fourth season has been confirmed to arrive later this year. Tulsa King has also held strong on Paramount+ streaming charts. outlasting competitors including Landman. which stars Billy Bob Thornton. and Mayor of Kingstown. starring Jeremy Renner.
Even with that momentum, Stallone isn’t slowing down. News broke yesterday that Stallone and his Balboa Productions banner are teaming with The Walking Dead veteran Channing Powell to adapt 4MK. the novel by J.D. Parker, into an official series. The project is still in the early stages of development. and it isn’t clear yet whether Stallone will star in the series or serve as an executive producer. Either way, the adaptation is moving forward.
What’s also still missing from the picture is the most practical detail for fans: when 4MK will stream. That timing hasn’t been announced, and it may depend on when a streamer or network acquires the rights for distribution.
4MK is set in Chicago and centers on detective Sam Porter as he hunts for the Four Monkey Killer. a serial murderer who has terrorized the city for years. The killer leaves behind a brutal signature—removing the ears. eyes. and tongues of his victims—while staging each crime scene as a message. The crimes are tied to the killer’s ruthless “code” of personal judgment. including plans to expose corruption until the city is “cleansed.”.
The show is described as a blend of familiar thrills for fans who miss Dexter—while also promising the “Bosch” itch, with the inevitable police hunt closing in on the killer.
The two worlds Stallone is stepping between feel connected by the same pursuit: in Tulsa King. Dwight Manfredi is built to handle power and consequences; in 4MK. Sam Porter is drawn into a long-running case shaped by a killer’s escalating obsession. One series has the quiet confidence of a criminal kingmaker. The other has a citywide countdown written into every crime scene.
For now, Tulsa King remains the anchor. All three seasons are available on Paramount+, and Stallone’s Dwight “The General” Manfredi is set to return with the fourth season confirmed for later this year. As for 4MK, the series is still being shaped—only the direction feels clear.
Nothing has been announced about a release date for 4MK yet in the materials available. but the project is already being framed as a major crime push. When the adaptation eventually lands. the story will come with a clear starting point: Detective Sam Porter. the Four Monkey Killer. and a Chicago built to face what happens when corruption meets a psychopath with a mission.
