We could sit here and pick apart the newly released X-Men: Days of Future Past trailer, but we’ll let director Bryan Singer do the job for us. Singer recently took time out of his busy schedule to comment on some screengrabs from the trailer and provide behind-the-scenes info for their captions.

The film stars Hugh Jackman, James McAvoy, Michael Fassbender, Jennifer Lawrence, Nicholas Hoult, Ian McKellan, Patrick Stewart, Peter Dinklage, Anna Paquin, Ellen Page, Shawn Ashmore, Omar Sy, and Halle Berry. X-Men: Days of Future Past opens in 3D May 23, 2014. Hit the jump to see what Singer had to say.

Here’s a sample of images and captions from Singer’s X-Men: Days of Future Past. Be sure to head over to Empire for many more:

“The grey in the hair is something I took from X-Men Days Of Future Past, it’s a look in the comic,” says Singer. “I liked it, even though he hasn’t really aged physically it’s something that shows how tough things have gotten in the future, and brought that out in him and given him a little more world-weariness.”

“She’s one of the last surviving X-Men in this post-apocalyptic world,” explains Singer of Storm’s place in the movie. “She’s part of that with Wolverine and Charles and Magneto, they’re some of the last folk standing from the original X-Men. They’re at the spearhead of this mission, this last chance at saving the world. This is their only hope, their mission into time. Can you actually go back and affect time? Can you go back and change things or will time correct itself? Will history fight you back and is your destiny pre-determined or can you change it?”
