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.

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.

Awakening in 1973, Logan goes to the X-Mansion, learning from Hank McCoy that the school has been closed for years due to the Vietnam War, and Lehnsherr has been imprisoned for assassinating JFK.

In a post-credits scene set in ancient Egypt, a crowd chants to En Sabah Nur, who telekinetically elevates rocks to build pyramids as his Four Horsemen observe from afar.

[68] He originally wanted a different First Class sequel helmed by another director with a young Wolverine possibly played by Tom Hardy, before returning to direct Days of Future Past (set in the 1980s) himself.

[95] Stan Lee, co-creator of the X-Men, was scheduled to shoot a cameo appearance in late August 2013 at Montreal, Canada, but ultimately chose to attend the Fan Expo in Toronto instead.

Myhre used styles from molded plastics from the 1970s to design Sentinels from that period,[16] and cited inspiration from both the cars of the decade and "those wonderful TV sets that were round with smoked glass panels".

The overall style was bulky to fit "the traditional idea of a robot looks like",[110] and drew the most from the comics version, such as the purple color and a humanoid shape, while trying to stand out on its own with its retro design.

Thus their design is sleek and feminine, with a body covered in mechanical scales that move during the process of adapting to a mutant's attack, while also featuring angular and dark faces to enhance the intimidation.

The future robots would feature what Singer described as "biomechanical technology to transform to adapt to other mutants, to take on their physicality and some of their powers to use against mutantkind", which the director imagined to be fueled by nanotechnology and "the ability to really change things almost at a molecular level".

The environment work based on Washington, D.C. required the team to study period references of the National Mall and White House, and photograph almost all of RFK Stadium to create a detailed digital replica.

After doing a LIDAR scan of the kitchen set, the digital recreation added many computer-generated props—cooking gear, cutlery, vegetables and water released by a fire sprinkler system—rendered in near microscopic detail regarding placement and lighting, particularly because the footage had to work in 3D.

To simulate Quicksilver running on the walls, Evan Peters and a stunt double were filmed in both the set being suspended by a harness and on a treadmill that stood in front of a chroma key green screen.

[124] In July 2013, Singer, writer Simon Kinberg, producers Lauren Shuler Donner and Hutch Parker, together with cast members Jennifer Lawrence, Evan Peters, Omar Sy, Elliot Page, Shawn Ashmore, Anna Paquin, Halle Berry, Ian McKellen, Patrick Stewart, Hugh Jackman, James McAvoy, Michael Fassbender, Nicholas Hoult, and Peter Dinklage presented at the 2013 San Diego Comic-Con.

[134] Jason Callina of New Jersey's Herald News gave the trailer a positive response, saying, "it is fantastic to see characters that I grew up with in the flesh ... we still have to wait till the end of May to see if Fox succeeded, but for now they have my interest".

Child wrote, "overloading the movie with superheroes might please fans of the comic books, but the rest of us will be chewing on our own spleens when the umpteenth brightly coloured dude turns up to spout one line of dialogue, then drop off the map".

In the scene, which is set during the Vietnam War, Mystique tries to infiltrate a military camp led by William Stryker to recruit fellow mutants Havok, Ink, and Toad.

According to the suit filed by attorney Jeff Herman, Singer was alleged to have drugged and raped actor and model Michael Egan in Hawaii after meeting him at parties hosted by convicted sex offender Marc Collins-Rector in the late 1990s.

[147] In early August 2014, Egan sought to withdraw his lawsuit via a Request for Court Order of Dismissal, and asked that it be granted "without prejudice or an award of costs or fees, in the interest of justice.

"[149] According to the lawsuit, Goddard and Singer met the man for sex when he was a minor and engaged in acts of "gender violence" against him while in London for the premiere of Superman Returns.

[152][153] Author Bret Easton Ellis alleged that two of his former partners had attended underage sex parties hosted by Singer and fellow director Roland Emmerich.

The promotion included advertising, in-restaurant merchandising, collectors' cups, and a film-themed burger, the Western "X-Tra" Bacon Thickburger,[155] sold at CKE Restaurants outlets Hardee's and Carl's Jr. Zachary Eller, senior vice president of marketing partnerships & promotions at 20th Century Fox, said, "their fun and irreverent advertising campaigns are a great fit with our film and we couldn't be more thrilled to join together to feed mutants everywhere!

The SUV made its debut at the 2015 Australian Open, with a series of videos featuring Rafael Nadal teaming up with the X-Men to save the tennis event from the Sentinels.

It added 17 minutes of previously unused footage, including a subplot involving Anna Paquin's character Rogue, whose role was reduced to a brief cameo in the theatrical release.

In another major scene, Mystique stops at the X-Mansion the night before the Sentinel-unveiling ceremony, nearly rekindles her previous romance with Beast, and destroys Cerebro the following morning to prevent Xavier from finding her.

A new mid-credits scene shows Bolivar Trask imprisoned at Magneto's former prison cell beneath the Pentagon for selling military secrets to foreign countries.

[4] Deadline Hollywood calculated the net profit of the film to be $77.3 million, accounting for production budgets, P&A, talent participations, and other costs, with box office grosses, and ancillary revenues from home media, placing it sixteenth on their list of 2014's "Most Valuable Blockbusters".

[169] It became the highest-grossing X-Men film in Argentina, Australia, Austria, Belgium, Brazil, China, Colombia, Croatia, Czech Republic, Denmark, Ecuador, Egypt, Finland, France, Hong Kong, Hungary, India, Ireland, Israel, Italy, Lebanon, Malaysia, Mexico, the Netherlands, New Zealand, Norway, the Philippines, Poland, Singapore, Slovakia, South Korea, Sweden, Thailand, the United Kingdom and Venezuela.

The website's critical consensus reads, "X-Men: Days of Future Past combines the best elements of the series to produce a satisfyingly fast-paced outing that ranks among the franchise's finest installments.

[183] David Rooney of The Hollywood Reporter said, "While it's more dramatically diffuse than the reboot and lacks a definitive villain, the new film is shot through with a stirring reverence for the Marvel Comics characters and their universe".
