X-Men: Days of Future Past is a 2014 American superhero film directed and produced by Bryan Singer and written by Simon Kinberg from a story by Kinberg, Jane Goldman, and Matthew Vaughn. 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, 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 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.
Convinced that mutants pose a threat to humanity, Dr. Bolivar Trask (Peter Dinklage) develops the Sentinels, enormous robotic weapons that can detect a mutant gene and zero in on that person. In the 21st century, the Sentinels have evolved into highly efficient killing machines. With mutants now facing extinction, Wolverine (Hugh Jackman) volunteers to go back in time and rally the X-Men of the past to help change a pivotal moment in history and thereby save their future.
