Producer Bryan Singer confirmed earlier today that the sequel to X-Men: First Class will be called X-Men: Days of Future Past. Here's what he had to say about the highly-anticipated superhero follow-up.

"I can say it's being written right now, and we'll start shooting in a couple of months. It's going to be very ambitious. It's called Days of Future Past, and it deals with aspects of not only that comic, but some very new things."

The Days of Future Past story line from the Marvel comic books deals with the idea of an alternate future, where mutants are hunted down by Sentinels, after the Brotherhood of Evil Mutants killed an important Senator. When asked if the sequel may cross over into past X-Men movies, the producer revealed they plan on expanding this universe.

"I think there's a strong desire to broaden out the universe. The X-Men universe, on its own, is just as big as the Marvel universe. I think it's time to reach out and explore it, and perhaps even bring some connectivity between the films. You may see some of that."

We reported in April that the sequel will begin production in January, after Jennifer Lawrence wraps on The Hunger Games: Catching Fire. CLICK HERE to watch the video interview with Bryan Singer.
