“The X-Men are sort of a fighting team, so it was always an attempt at being realistic to have them in fighting uniforms, flight suits, things like that. In X-Men: First Class, which I produced and wrote the story for, we harked back to the original colors of the original costumes from the 1963 comic, which were all the same, they were all uniforms. They eventually evolved into the colors.
