X-Men 3 reportedly has found someone to replace Lost's Maggie Grace who, frankly, was a touch long in the tooth for the role as Kitty Pryde. Eighteen-year-old actress Ellen Page (Hard Candy) will tackle the mutant ingénue instead, reports IGN FilmForce. X3 begins filming next week in Vancouver, and is set for a May 26, 2006, release much to the delight of high-school geeks who weren't going to prom anyway.
