Wow, I didn’t know that about the original trilogy. That’s kinda terrible.
As for the Force Awakens — I noticed that too and it’s one of my favorite things about the film, how women and POC are just taking part in all roles and it’s totally no big deal. I was struck by how much that stood out for me and I realized it’s because it’s really rare. In most films, especially where there’s fighting scenes, the vast majority of characters will be men, and we’ve come to believe that this is normal and reflects reality.
