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) based on the team of the same name appearing in DC Comics publications. It is intended to match director Zack Snyder's original vision for the film, prior to his departure from the production and subsequent studio interference. The film follows Batman, Wonder Woman, Cyborg, Aquaman, The Flash, and a revived Superman as they form an alliance to stop the extradimensional New God Steppenwolf and his army of Parademons from conquering Earth for his overlord Darkseid.
