X-Men: Days of Future Past is a 2014 superhero film directed and co-produced by Bryan Singer and written by Simon Kinberg from a story he created with Jane Goldman and Matthew Vaughn. The film is based on the Marvel Comics superhero team the X-Men, the fifth mainline installment of the X-Men film series, a sequel to X-Men: The Last Stand (2006) and X-Men: First Class (2011), a follow-up to The Wolverine (2013), and the seventh installment overall. It stars 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.
