X-Men in the context of "List of films based on Marvel Comics publications"

X-Men is an American superhero film series based on the Marvel Comics superhero team of the same name. It was produced by 20th Century Fox and Marvel Entertainment from 2000 to 2020.

Fox obtained the film rights to the team and other related characters in 1994 for $2.6 million. They first produced the X-Men film trilogy consisting of X-Men (2000), X2 (2003), and X-Men: The Last Stand (2006). After each film outgrossed its predecessor, further films were released, set in the same shared universe. These included three spin-off films centered around Wolverine (X-Men Origins: Wolverine in 2009, The Wolverine in 2013, and Logan in 2017), two films centered around Deadpool (Deadpool in 2016 and Deadpool 2 in 2018), and the spin-off The New Mutants (2020). A prequel series to the original trilogy began with X-Men: First Class (2011), and was followed by X-Men: Days of Future Past (2014), which also served as a sequel to X-Men: The Last Stand and a soft reboot for the series as a whole; the prequel series continued with X-Men: Apocalypse (2016) and Dark Phoenix (2019). In addition to the thirteen films, four of the films received a total of five additional cuts, and two television series – Legion (2017–2019) and The Gifted (2017–2019) – were released.

Marvel Comics is an American comic book publisher, a property of the Walt Disney Company since December 31, 2009, and a subsidiary of Disney Publishing Worldwide since March 2023. Marvel was founded in 1939 by Martin Goodman as Timely Comics, and by 1951 had generally become known as Atlas Comics. The Marvel era began in August 1961 with the launch of The Fantastic Four and other superhero titles created by Stan Lee, Jack Kirby, Steve Ditko, and numerous others. The Marvel brand, which had been used over the years and decades, was solidified as the company's primary brand.

Marvel counts among its characters such well-known superheroes as Spider-Man, Wolverine, Iron Man, Captain America, Hulk, Thor, Doctor Strange, Daredevil, Black Panther, and Captain Marvel, as well as popular superhero teams such as the Avengers, X-Men, Fantastic Four, and Guardians of the Galaxy. Its stable of well-known supervillains includes Doctor Doom, Magneto, Green Goblin, Venom, Red Skull, Loki, Ultron, Thanos, Apocalypse, and Galactus. Most of Marvel's fictional characters operate in a single reality known as the Marvel Universe, with most locations mirroring real-life places; many major characters are based in New York City. Additionally, Marvel has published several licensed properties from other companies. This includes Star Wars comics, twice from 1977 to 1987, and again since 2015.

Stan Lee (born Stanley Martin Lieber /ˈliːbər/; December 28, 1922 – November 12, 2018) was an American comic book writer, editor, publisher and producer. He rose through the ranks of a family-run business called Timely Comics which later became Marvel Comics. He was Marvel's primary creative leader for two decades, expanding it from a small publishing house division to a multimedia corporation that dominated the comics and film industries.

In collaboration with others at Marvel – particularly co-plotters and artists Jack Kirby and Steve Ditko – he co-created iconic characters, including Spider-Man, the X-Men, Iron Man, Thor, the Hulk, Ant-Man, the Wasp, the Fantastic Four, Black Panther, Daredevil, Doctor Strange, the Scarlet Witch, and Black Widow. These and other characters' introductions in the 1960s pioneered a more naturalistic approach in superhero comics. In the 1970s, Lee challenged the restrictions of the Comics Code Authority, indirectly leading to changes in its policies. In the 1980s, he pursued the development of Marvel properties in other media, with mixed results.

Jack Kirby (/ˈkɜːrbi/; born Jacob Kurtzberg; August 28, 1917 – February 6, 1994) was an American comic book artist, widely regarded as one of the medium's major innovators and one of its most prolific and influential creators. He grew up in New York City and learned to draw cartoon figures by tracing characters from comic strips and editorial cartoons. He entered the nascent comics industry in the 1930s, drawing various comics features under different pen names, including Jack Curtiss, before settling on Jack Kirby. In 1940, he and writer-editor Joe Simon created the highly successful superhero character Captain America for Timely Comics, predecessor of Marvel Comics. During the 1940s, Kirby regularly teamed with Simon, creating numerous characters for that company and for National Comics Publications, later to become DC Comics.

After serving in the European Theater in World War II, Kirby produced work for DC Comics, Harvey Comics, Hillman Periodicals and other publishers. At Crestwood Publications, he and Simon created the genre of romance comics and later founded their own short-lived comic company, Mainline Publications. Kirby was involved in Timely's 1950s iteration, Atlas Comics, which in the next decade became Marvel. There, in the 1960s, Kirby co-created many of the company's major characters, including Ant-Man, the Avengers, the Black Panther, the Fantastic Four, the Hulk, Iron Man, the Silver Surfer, Thor, and the X-Men, among many others. Kirby's titles garnered high sales and critical acclaim, but in 1970, feeling he had been treated unfairly, largely in the realm of authorship credit and creators' rights, Kirby left the company for rival DC.

The Avengers are a superhero/antihero team appearing in American comic books published by Marvel Comics, created by writer-editor Stan Lee and artist/co-plotter Jack Kirby. The team made its debut in The Avengers #1 (cover-dated September 1963). Labeled "Earth's Mightiest Heroes", the original Avengers consisted of Iron Man, Ant-Man, Hulk, Thor, and Wasp. Captain America was discovered trapped in ice in issue #4, and joined the group after they revived him. The Avengers are an all-star ensemble cast of established superhero characters from the Marvel Comics portfolio.

Diegetically, these superheroes usually operate independently but occasionally assemble as a team to tackle especially formidable villains. This in contrast to certain other superhero teams such as the X-Men, whose characters were created specifically to be part of their team, with the team being central to their identity. The Avengers were created to create a new line of books to sell and to cross-promote Marvel Comics characters.

The Justice League, or Justice League of America (JLA), is a group of superheroes appearing in American comic books published by DC Comics. The team first appeared in The Brave and the Bold #28 (March 1960). Writer Gardner Fox conceived the team as a revival of the Justice Society of America, a similar team from DC Comics from the 1940s which had been pulled out of print due to a decline in sales. The Justice League is an all-star ensemble cast of established superhero characters from DC Comics' portfolio. Diegetically, these superheroes usually operate independently but occasionally assemble as a team to tackle especially formidable villains. This is in contrast to certain other superhero teams such as the Doom Patrol or Marvel’s X-Men whose characters were created specifically to be part of the team, with the team being central to their identity. The cast of the Justice League usually features a few highly popular characters who have their own solo books, such as Superman, Batman, and Wonder Woman, alongside several lesser-known characters who benefit from exposure.

The Justice League was created to boost the profiles and sales of these characters through cross-promotion and helped develop the DC Universe as a shared universe, as it is through teams like the Justice League that the setting's characters regularly interact with each other.
