Six feature-length action adventures based on the Marvel comic strip.
In 'X-Men' (2000), mutants Professor Charles Xavier (Patrick Stewart) and Magneto (Ian McKellen) are former friends, but look set to become mortal enemies when a fascist US senator calls for the registration of all humans with abnormal powers.
While telepath Xavier, who runs an altruistic academy for superhuman 'X-Men', wishes to enlighten non-mutants and break down the prejudices which divide them, Magneto believes that the only solution is for the mutants to take over.
Wolverine (Hugh Jackman) - an aggressive loner with an adamantium skeleton and the ability to heal his body of any wound - and teenager Rogue (Anna Paquin), who can absorb the life force of others simply by touching them, are selected by Xavier to join his academy, but it isn't long before Magneto's followers are attempting to capture them so that they can assist in his plan for world domination.
In the sequel, 'X-Men 2' (2003), Xavier, Wolverine and the X-Men find themselves in the firing line after a failed assassination attempt on the president points the finger at the school.
It was in fact the mysterious teleporter Nightwalker (Alan Cumming) who ordered it, and, in an attempt to clear their names, the X-Men are led into a trap set by the evil William Stryker (Brian Cox), a mysterious scientist apparently working for the government.
In the third film, 'X-Men: The Last Stand' (2006), the mutants are given the option of giving up their powers and becoming human after a private laboratory supported by the government finds a way to use the DNA of a powerful boy to correct the mutants.
However, Magneto opposes and decides to join a force to fight against the government and kill the mutant boy.
Meanwhile, Jean Grey (Famke Janssen) resurrects, uncontrolled by Xavier, and with the personality of the powerful Dark Phoenix.
She destroys Cyclops (James Marsden) and Xavier and allies herself to the evil forces of Magneto, making them almost invincible.
The fourth film in the franchise, 'X-Men: Origins - Wolverine' (2009), is a prequel to the other three films.
Jackman reprises his role as Wolverine, who, some 20 years before the action of the original movie, is seeking revenge on his half-brother Victor Creed (Liev Schreiber) for the death of his girlfriend, and eventually signs up to the ominous Weapon X programme. 'X-Men: First Class' (2011) charts the beginning of the saga, following Professor X (James McAvoy) and Magneto (Michael Fassbender) through their formative years in the 1960s as they come to terms with their newfound superpowers.
Initially close friends who work together to fight against evil, the two men are driven apart by a conflict of opinion that ultimately leads to the eternal war between Magneto's Brotherhood and Professor X's X-Men.
Finally, 'The Wolverine' (2013) finds the eponymous hero vulnerable, alone and at his lowest point after the events of 'X-Men: The Last Stand'.
Drawn to modern-day Japan by the gratitude of a wealthy industrialist from his past who secretly covets his healing powers, Logan aka Wolverine soon finds himself up against the deadly charms of a femme fatale known as 'The Viper' (Svetlana Khodchenkova), whilst having to confront samurai steel and lethal ninjas as his destiny draws him towards a winner-takes-all battle with his ultimate foe 'The Silver Samurai' (Will Yun Lee).
