Days of Future Past had an enormous cast, but only one of its main characters was a woman. All of the characters of color were restricted to backup roles in the dystopian future scenes: A battle sequence where all of the meaty storytelling remained in the hands of Magneto and Professor X.
Storm, along with newcomers Bishop, Sunspot, Blink (played by Chinese megastar Fan Bingbing) and Warpath (a little-known Native American X-Man), were selected for their cool, flashy powers, but had little dialogue and no character development whatsoever.
This sudden influx of racial diversity was meant to counterbalance the overwhelmingly white and male nature of the movie’s main cast. Unfortunately, it also served to remind us that while Wolverine, Xavier, Magneto, and Hank McCoy got to chase around after Mystique back in the 1970s, the main role of non-white characters was to provide interchangeable expository dialogue and keep Wolverine alive for long enough to save the world.
The purpose of Wolverine’s mission was to erase this future timeline so the original trilogy’s X-team could thrive, safe once more at the Xavier School. In the utopian future we see at the end of the film, Blink, Bishop, Sunspot and Warpath are nowhere to be seen.
