As the trade previously reported, tensions between the studios were running high last month as Fox was considering filming the Matthew Vaughn-directed X-Men follow-up in the fall, potentially conflicting with Lionsgate's plans for Hunger Games. Fox, which cast Lawrence as the shape-shifting character Mystique in Summer 2010, months before Lionsgate chose her to play Katniss Everdeen in March 2011, has the right to exercise the option on her contract if it conflicts with another Hunger. That's true even though Lawrence is part of a large ensemble in X-Men but is the clear star of the Hunger franchise.
Lawrence will reprise her role of Mystique and is expected to be joined again by the likes of James McAvoy, Michael Fassbender, Rose Byrne, January Jones, Nicholas Hoult, Caleb Landry Jones and Lucas Till
