Featuring an ensemble cast consisting of Patrick Stewart, Hugh Jackman, Ian McKellen, Halle Berry, Famke Janssen, James Marsden, Bruce Davison, Rebecca Romijn-Stamos, Ray Park, and Anna Paquin, the film depicts a world where an unknown proportion of people are mutants, possessing superhuman powers that make them distrusted by normal humans.
