The explosive X-Men motion picture trilogy officially draws to a close with this release that finds Rush Hour director Brett Ratner stepping in for Bryan Singer to tell the tale of a newly discovered mutant "cure," and the polarizing effect it has on mutant/man relations. With the pressure on mutants to give up their powers and pledge alliance with the human race reaching a critical turning point, Professor Charles Xavier (Patrick Stewart) urges tolerance and understanding as his nemesis Magneto (Ian McKellen) gathers a powerful resistance in preparation for the ultimate war against humankind. Hugh Jackman, Halle Berry, Anna Paquin, and James Marsden return to reprise the roles they played in the previous two X-Men films, with Kelsey Grammer and Vinnie Jones joining the cast as Beast and Juggernaut respectively.
