Justice League is a 2017 American superhero film based on the DC Comics superhero team of the same name, distributed by Warner Bros. Pictures. The fifth installment in the DC Extended Universe (DCEU), the film is directed by Zack Snyder with a screenplay by Chris Terrio and Joss Whedon, from a story by Terrio and Snyder. It features an ensemble cast that includes Ben Affleck, Henry Cavill, Amy Adams, Gal Gadot, Ezra Miller, Jason Momoa, Ray Fisher, Jeremy Irons, Diane Lane, Connie Nielsen, and J. K. Simmons. In Justice League, the superhero team, consisting of Batman, Wonder Woman, Flash, Aquaman, and Cyborg forms to honor the memory of Superman and to save earth from the catastrophic threat of Steppenwolf and his army of Parademons.
The film was announced in October 2014, with Snyder on board to direct and Terrio attached to write the script. Initially titled Justice League Part One, with a second part to follow in 2019, the second film was indefinitely delayed to accommodate a standalone Batman film with Affleck. Principal photography commenced in April 2016 and ended in October 2016. Snyder then hired Joss Whedon to write scenes that would be filmed during reshoots; however, Snyder left the project in May 2017 following the death of his daughter. Whedon was hired to oversee the remainder of post-production, including directing additional scenes written by himself. Snyder received sole director credit for the film, with Whedon receiving a screenplay credit.
With an estimated production budget of $300 million, it is one of the most expensive films ever made. Justice League premiered in Beijing on October 26, 2017, and was released in the United States in 2D, 3D and IMAX on November 17, 2017. The film performed below expectations at the box office, having grossed $655 million worldwide and $227 million in North America, both the lowest of the DCEU, against a break-even point of around $750 million. It received mixed reviews from critics; the action sequences and performances (particularly Gadot and Miller) were praised, while the plot, writing, pacing, villain and overuse of CGI were criticized. The film’s tone met with a polarized reception; while some appreciated the lighter tone than previous DC films, others found it inconsistent.
