What we know
Chapter 51 (2026)
An elusive serial killer known as the Hollywood Killer turns a high-profile film production into a grisly crime scene, murdering three actresses and casting a dark shadow over the troubled project. As fear, speculation, and chaos spread behind the cameras, the production becomes forever linked to a case that shocks Hollywood and remains unresolved. Years later, former FBI agent Thomas Scott reopens the cold case, revisiting the events surrounding the murders and uncovering secrets that refuse to stay buried.
It shares its release window with Supergirl, so expect the two fanbases to be reacting side by side.
The theatrical release lands June 23, 2026.
