Deadpool 2 is a 2018 American superhero film based on the Marvel Comics character Deadpool. It is the eleventh installment in the X-Men film series, and is the sequel to 2016's Deadpool. The film was directed by David Leitch from a screenplay by Rhett Reese, Paul Wernick, and Ryan Reynolds, who stars in the title role alongside Josh Brolin, Morena Baccarin, Julian Dennison, Zazie Beetz, T.J. Miller, Brianna Hildebrand, and Jack Kesy. In the film, Deadpool forms the X-Force to protect a young mutant from the time-traveling soldier Cable.
Plans for a sequel to Deadpool began before the original film's release, and were confirmed in February 2016. Though the original creative team of Reynolds, Reese, Wernick, and director Tim Miller were quickly set to return for the second film, Miller left the project in October 2016 due to creative differences with Reynolds and was soon replaced by Leitch. An extensive casting search took place to fill the role of Cable, with Brolin ultimately cast. Filming took place in British Columbia from June to October 2017. The film is dedicated to stuntwoman Joi "SJ" Harris, who died in a motorcycle accident during filming.
Deadpool 2 was released in the United States on May 18, 2018 by 20th Century Fox. It grossed over $785 million worldwide, becoming the ninth-highest-grossing film of 2018, as well as the highest-grossing R-rated film of all time and the highest-grossing X-Men film of all time. The film received positive reviews from critics, who praised its humor, acting (particularly Reynolds, Brolin, and Beetz's performances), story, and action sequences. Some critics considered it better than the first film, although others criticized its tone and script. A PG-13 rated version of the film, titled Once Upon a Deadpool, released on December 12, 2018, to mixed reviews.
