According to Hypable, "X-Men: First Class" gave Fox the opportunity to showcase "new story lines with familiar characters." The movie has also "opened the door for a variety of spinoff films starring the younger cast" such as Jean Grey, portrayed by Sophie Turner.

Simon Kinberg will reportedly helm the upcoming "X-Men: Supernova" film, per Collider. The director has also allegedly finished writing the screenplay for the movie.
