Batman: The Long Halloween, Part 1 (2021)

Atrocious serial killings on holidays in Gotham send The World’s Greatest Detective into action—confronting both organized crime and a mysterious murderer—in Batman: The Long Halloween, Part One, the next entry in the popular series of the DC Universe Movies. 

Inspired by the iconic mid-1990s DC story from Jeph Loeb and Tim Sale, Batman: The Long Halloween, Part One begins as a brutal murder on Halloween prompts Gotham’s young vigilante, the Batman, to form a pact with the city’s only two uncorrupt lawmen (Police Captain James Gordon and District Attorney Harvey Dent) in order to take down The Roman, head of the notorious and powerful Falcone Crime Family. But when more deaths occur on Thanksgiving and Christmas, it becomes clear that instead of ordinary gang violence, they’re also dealing with a serial killer—the identity of whom, with each conflicting clue, grows harder to discern. Few cases have ever tested the wits of the World’s Greatest Detective like the mystery behind the Holiday Killer.
