X-Men Cast

Hugh Jackman as Logan / Wolverine: A tough, rugged, belligerent loner who makes a living in cage fights. He has lived for fifteen years without memory of who he is, apart from his dog tags marked "Wolverine" and an adamantium-encased skeleton (as well as adamantium claws). He has the ability to heal rapidly from numerous injuries, including the surgery that bonded the metal to his skeleton, which makes his age impossible to determine.
Patrick Stewart as Professor Charles Xavier: Founder of the X-Men and the Xavier School for Gifted Youngsters, Xavier hopes for peaceful coexistence between mutantkind and mankind and is regarded as an authority on genetic mutation. Although he is restricted to a wheelchair, he is a powerful mutant with vast telepathic abilities. Along with Magneto, he is the inventor of the Cerebro supercomputer, which further amplifies his abilities.
Ian McKellen as Erik Lehnsherr / Magneto: A Holocaust survivor, he and Xavier were once allies, and they built Cerebro together. However, his belief that humans and mutants could never co-exist lead to their separation. He has powerful magnetic abilities and a sophisticated knowledge in matters of genetic manipulation, which he uses to plan a mutation of the world leaders to allow mutant prosperity.
Anna Paquin as Marie / Rogue: A seventeen-year-old girl, forced to leave her family in Mississippi after putting her boyfriend in a coma by kissing him. If she touches anyone, she absorbs their strength, memories and abilities, potentially killing them. During her travels, she meets Wolverine, who becomes her closest friend. She begins to have a romance with Bobby Drake.
Famke Janssen as Dr. Jean Grey: She is in a relationship with Cyclops and works as the doctor of the X-Mansion. She has the powers of telekinesis and telepathy.
Bruce Davison as Senator Robert Kelly: An anti-mutant politician that supports a Mutant Registration Act and wishes to ban mutant children from schools. He is kidnapped by Magneto in a test of his mutation machine, which causes his body to turn into a liquid-like substance.
James Marsden as Scott Summers / Cyclops: He rescues Wolverine and Rogue from a truck explosion, taking them to safety to the X-Mansion where they live. He is the second leader of the X-Men behind Xavier, and is the team's field leader when they are out on missions as well as an instructor at the Institute. He is in love with Jean Grey and has a relationship with her. He produces a strong red beam of force from his eyes, which is only held in check by specialized ruby-quartz goggles and sunglasses.
Halle Berry as Ororo Munroe / Storm: She works as a teacher at the X-Mansion and has the ability to manipulate the weather. Ororo has become bitter with other people's hatred for mutants, and while comforting a dying Senator Kelly says that she sometimes hates humans.
Rebecca Romijn-Stamos as Mystique: Magneto's loyal second-in-command, her mutant ability to alter her shape and mimic any human being is almost secondary to her role as "the perfect soldier". She is an agile fighter, expert martial artist, and seems completely facile with modern technology. It is unknown whether her blue, scaly skin is her normal physical expression or if it is a choice which sets herself apart from "normal" humans.
Ray Park as Toad: A very agile fighter with a menacing streak and a long, prehensile tongue, who can also spit a slimy substance onto others.
Tyler Mane as Sabretooth: A ferocious, feline-like fighter who attacks Wolverine and Rogue in Canada before being stopped by Storm and Cyclops. He is a brutal and sadistic henchman of Magneto, and wields claws extending past each finger.
Shawn Ashmore as Bobby Drake / Iceman: A student at Xavier's School For Gifted Youngsters who takes a liking to Rogue. He can change temperatures to subzero degrees and use the moisture in the air to create ice.
David Hayter, Stan Lee, and Tom DeSanto make cameo appearances. George Buza, the voice of Beast in X-Men: The Animated Series, appeared as the truck driver who drops Rogue off at the bar at which Wolverine works. Gambit was considered for one of the students at the X-Mansion. Singer remembered, "We thought about Gambit as the young boy on the basketball field, but the feeling was that if he has the basketball and then releases it and it exploded, [then] people would be like 'What's wrong with those basketballs?'" The success of X-Men (alongside Blade) started a reemergence for the comic book and superhero film genre. A young Colossus appears sketching a picture in one scene.
