Behind The Scenes
Star Wars Episode VII: The Force Awakens Disney was saying "Look we make strong female characters Star Wars has never done that" which was a debatable claim. Disney sounded a little hypocritical after the movie came out considering Phasma, like a lot of the villains in the movie, turned out to be pretty weak.
