In an interview with Yahoo, Brian Singer hinted that the coming X-Men Apocalypse feature will possibly have the X-Men in tradition gear as represented in the comics, which typically was yellow and dark navy blue:
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 hark back to the original colours of the original costumes from the 1963 comics, which were all the same, they were uniforms. They eventually involved into the colours.
I will say that in X-Men: Apocalypse, there is a chance – without giving anything away – that you may get closer to seeing what I think, you are interested in seeing. I know its something that I’ve been interested in. I just always wanted to do it the right way.
Singer also spoke about the younger versions of the classic characters which will feature in X-Men Apocalypse and the differences they have in comparisons to earlier representations of X-Men characters in 20th Century Fox’s canon:
These are very different characters than they were in the films X-Men 1, 2, and 3. They are at times in their lives when they are at the most opposite of what they would become. That’s a thrill to me, to take characters I crafted so many years ago and flip them completely on their side and show how they evolved and began.
20th Century Fox’s X-Men Apocalypse is directed by Bryan Singer and stars Jennifer Lawrence, Michael Fassbender, James McAvoy, Nicholas Hoult, Evan Peters, Ian McKellen, Rose Byrne, Sophie Turner, Tye Sheridan, Alexandra Shipp and Oscar Issac.
