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,[a] 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. In a dystopian 2023, Sentinel robots hunt and kill mutants, as well as humans who either possess the genetic potential to have mutant offspring or try to protect them. In Moscow, they attack X-Men survivors Kitty Pryde, Colossus, Blink, Warpath, Bishop, Iceman, and Sunspot.
The mutants sacrifice themselves to buy Kitty enough time to send Bishop’s consciousness a few days into the past to warn the others of the coming attack and ensure their survival. Having averted the attack, the group retreats to a remote Chinese temple and are joined by Storm, Logan, Charles Xavier, and Erik Lehnsherr. Xavier explains that the Sentinels were originally conceived by Bolivar Trask, a weapons designer whom Raven Darkhölme assassinated in 1973.
In response, the government captured Raven and experimented on her, using her DNA to create Sentinels capable of adapting to any mutant power. Xavier plans to go back in time to 1973 and prevent Trask’s assassination in the hopes of altering the future. However, upon learning that time-traveling too far would kill Xavier, Logan volunteers instead, as his regenerative abilities would allow him to survive.
