Fox has released a new trailer for X Men: Days of Future Past, which sees a mashup of two different generations of mutants as the original X-Men join forces with their younger selves in a battle to save humanity. 

Halle Berry reprises her role as Storm in a cast that includes Hugh Jackman, James McAvoy, Michael Fassbender, Jennifer Lawrence, Anna Paquin, Ellen Page, Shawn Ashmore, Nicholas Hoult, Peter Dinklage, Ian McKellen, Patrick Stewart and Omar Sy.  

The film hits theaters on May 23. 

Before that, catch Berry in Frankie & Alice, the feature drama inspired by a true story, that centers around a young woman (Berry) with multiple personality disorder who struggles to cope with her disease. Codeblack will open that film on April 4, 2014.
