X-Men: Days of Future Past

X-Men: Days of Future Past is a 2014 superhero film based on the Marvel Comics superhero team the X-Men. It is the seventh installment in the X-Men film series and a sequel to X-Men: First Class (2011). Directed by Bryan Singer and written by Simon Kinberg, the film features an ensemble cast, including Hugh Jackman, James McAvoy, Michael Fassbender, Jennifer Lawrence, Halle Berry, Anna Paquin, Elliot Page, Peter Dinklage, Ian McKellen, and Patrick Stewart. The story, inspired by the 1981 Uncanny X-Men storyline "Days of Future Past" by Chris Claremont and John Byrne, focuses on two time periods, with Logan traveling back in time to 1973 to change history and prevent an event that results in unspeakable destruction for both humans and mutants.

Vaughn had directed X-Men: First Class and was set to return in Days of Future Past but instead left for Kingsman: The Secret Service and the 2015 version of Fantastic Four. Singer, who had directed the first two X-Men films, returned as director, and brought along most of the crew from those productions. With a budget of $205 million, the film's principal photography began in Montreal, Quebec, in April 2013, and concluded in August, with additional filming and pick-ups taking place in November 2013 and February 2014. Twelve companies handled the visual effects.

X-Men: Days of Future Past premiered in New York City on May 10, 2014, and was theatrically released in the United States on May 23, by 20th Century Fox. The film received positive reviews from critics, who deemed it one of the finest in the series. It grossed $746 million, making it the sixth-highest-grossing film of 2014, and received an Academy Award nomination for Best Visual Effects. A sequel, X-Men: Apocalypse was released in 2016.
