Fan Casting X3 (2006)

The X-Men face their most formidable foe yet: one of their own, Jean Grey. As a cosmic force resurrects the telepath while taking over her body as its host, Jean tries wrestling with her newfound abilities she can neither comprehend nor contain. With the world out of balance as she grows more powerful, the team must try to find a way to not only save their former friend, but prevent igniting a war between humans and fellow mutants who want to weaponize or kill her by any means necessary.
