Zack Snyder's Justice League is the 2021 director's cut of the 2017 American superhero film Justice League, the fifth film set within the DC Extended Universe (DCEU), which is based on the team of the same name appearing in DC Comics. It is intended to match director Zack Snyder's original vision for the film prior to his departure from the production. The film follows Batman (Ben Affleck), Wonder Woman (Gal Gadot), Cyborg (Ray Fisher), Aquaman (Jason Momoa), the Flash (Ezra Miller), and Superman (Henry Cavill) as they form an alliance to stop the extradimensional New God Steppenwolf (Ciarán Hinds) and his army of Parademons from conquering Earth for his overlord, Darkseid (Ray Porter).
