A double bill of mutant adventures directed by Bryan Singer. 'X-Men 1.5 - Extreme Edition' is a special edition of Singer's first offering.
Mutants Charles Xavier (Patrick Stewart) and Magneto (Ian McKellen) are former friends, but look set to become mortal enemies when fascistic US senator Robert Frank Kelly 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 admantium 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.
Whilst in 'X-Men 2' Professor Xavier (Stewart), Wolverine (Jackson), and the Academy for Gifted Youngsters find themselves in the firing line after a failed assasination 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.
As it soon becomes evident that Stryker's agenda is to destroy all mutants, the X-Men need to call in the help of many of their old friends and foe, including Magneto (McKellen), if they are to stop him.
