X-Men: Days of Future Past is a 2014 superhero film directed and produced by Bryan Singer and written by Simon Kinberg from a story by Kinberg, Jane Goldman, and Matthew Vaughn. A British-American venture, the film is based on the fictional X-Men characters that appear in Marvel Comics, the seventh installment of the X-Men film series and a sequel to X-Men: The Last Stand (2006), X-Men: First Class (2011) and The Wolverine (2013). It stars an ensemble cast, including Hugh Jackman, James McAvoy, Michael Fassbender, Jennifer Lawrence, Halle Berry, Nicholas Hoult, Anna Paquin, Ellen 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 Wolverine traveling back in time to 1973 to change history and prevent an event that results in doom for both humans and mutants.
Vaughn had directed X-Men: First Class and was set to return in Days of Future Past before leaving for Kingsman: The Secret Service and the 2015 version of Fantastic Four. Thus Singer, who had directed the first two X-Men films, made his return as a director, and brought along most of the crew from those productions. With a budget of $205 million principal photography began in Montreal, Quebec in April 2013 and concluded in August the same year, 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 on May 23 by 20th Century Fox. It is the second-best reviewed film in the X-Men film series following Logan, drawing favorable notices for its story, visual effects, action scenes, acting, thematic elements, and Singer’s direction. During its theatrical run, the film earned over $747 million worldwide, making it the sixth highest-grossing film of 2014, as well as the second highest-grossing film in the series behind Deadpool. The film received an Academy Award nomination for Best Visual Effects, making it the first X-Men film to be nominated for an Oscar. A sequel, titled X-Men: Apocalypse, was released on May 27, 2016.
