Sylvester Stallone, who gained fame through his role as Rocky Balboa, is currently starring as Dwight 'The General' Manfredi in the crime drama series 'Tulsa King'. The show, created by Taylor Sheridan, has aired three successful seasons and has a fourth season on the way, solidifying its place at the top of Paramount Plus streaming charts. In addition to his role in 'Tulsa King', Stallone is expanding his repertoire by adapting the novel '4MK' by J.D. Parker into a series through his production company, Balboa Productions. The story is set in Chicago and revolves around detective Sam Porter, who is on a relentless quest to catch the Four Monkey Killer, a serial murderer known for his brutal methods. The adaptation is expected to resonate with fans of crime thrillers, particularly those who enjoyed 'Dexter' and 'Bosch'. While it remains uncertain whether Stallone will star in '4MK' or serve only as an executive producer, the project is in its early development stages, with further details on its streaming release yet to be announced.
