X-Men': Could Jennifer Lawrence's Mystique get the next spin-off film

 20th Century Fox’s X-Men: Days of Future Past  doesn’t open until May 23, but that hasn’t stopped its producers from considering spin-off films (Hugh Jackman’s Wolverine is the only character so far to step out on his own), especially given the success that Marvel has had with The Avengers and its roster (Captain America, Thor, Iron Man). “There was a regime [at the studio] that didn’t see the worth in [spin-offs], and the current people who run Fox understand, embrace it, and we’re going to do right by it,” says producer Lauren Shuler Donner, who’s produced all of the X-Men films
