Batman v Superman: Dawn of Justice is a 2016 American superhero film based on the DC Comics characters Batman and Superman. Co-produced by Atlas Entertainment and Cruel and Unusual Films, and distributed by Warner Bros. Pictures, it is a follow-up to Man of Steel (2013) and the second installment in the DC Extended Universe (DCEU). The film was directed by Zack Snyder, written by Chris Terrio and David S. Goyer, and features an ensemble cast that includes Ben Affleck, Henry Cavill, Amy Adams, Jesse Eisenberg, Diane Lane, Laurence Fishburne, Jeremy Irons, Holly Hunter, and Gal Gadot. Batman v Superman: Dawn of Justice is the first live-action film to feature Batman and Superman together, as well as the first live-action cinematic portrayal of Wonder Woman. In the film, criminal mastermind Lex Luthor manipulates Batman into a preemptive battle with Superman, with whom Luthor is obsessed.
The film was announced at the 2013 San Diego Comic-Con after the release of Man of Steel. Snyder stated that the film would take inspiration from the Batman comic book series The Dark Knight Returns by Frank Miller but clarified that it would follow an original premise. The incarnation of Batman in the film is different from the character's previous portrayal in The Dark Knight Trilogy, serving as a cinematic reboot of the character. The film is also inspired by narrative elements from the "Death of Superman". Pre-production began at East Los Angeles College in October 2013, with principal photography starting in May 2014 in Detroit. Additional filming also took place in Illinois and New Mexico, concluding that December.
Batman v Superman: Dawn of Justice premiered at the Auditorio Nacional in Mexico City on March 19, 2016, and was released in the United States on March 25, 2016, in 2D, 3D, premium large formats, and 70 mm prints. Following a strong debut that set new box office records, the film experienced a historic drop in its second weekend and never recovered. Despite turning a profit, it performed well below expectations and received generally unfavorable reviews from critics for its tone, story, pacing, and characterization, though some praised its visual style and acting performances (particularly Affleck and Cavill). An extended cut dubbed the "Ultimate Edition", which features 31 minutes of additional footage, was released digitally on June 28, 2016, and on Blu-ray on July 19, 2016. A follow-up, Justice League, was released in November 2017.
