Justice League (2017) is a superhero film set in the DC Extended Universe (DCEU), directed by Zack Snyder and later completed by Joss Whedon. The story follows Bruce Wayne (Batman) and Diana Prince (Wonder Woman) as they unite a team of powerful heroes—Arthur Curry (Aquaman), Barry Allen (The Flash), and Victor Stone (Cyborg)—to combat a looming extraterrestrial threat.
Following the death of Superman (Henry Cavill) in Batman v Superman: Dawn of Justice (2016), Earth becomes vulnerable to an invasion by Steppenwolf, a powerful warrior seeking to unite three ancient artifacts known as the Mother Boxes. As Steppenwolf and his Parademon army wreak havoc, the newly formed Justice League struggles to work together. To stand a chance, they take a risky step—reviving Superman.
Despite behind-the-scenes challenges, the film delivers intense action, character-driven moments, and epic battles. Though criticized for inconsistent tone and CGI flaws, it features standout performances and thrilling sequences. The 2021 Zack Snyder’s Justice League later offered a darker, more cohesive director’s cut. Ultimately, Justice League (2017) showcases DC’s greatest heroes coming together in an action-packed battle to save humanity.
