Bryan Singer Reveals Secrets in the ‘X-Men: Days of Future Past’ Trailer

X-Men fans finally got a look at the long-awaited 'X-Men: Days of Future Past' trailer, and while no footage of the famous mutant-hunting Sentinel robots was present, we did get a rundown of all the returning (and some new) faces in this 'X-Men: First Class' sequel. We know there was a lot to take in in the short amount of time, so director Bryan Singer has offered up his own commentary on the trailer, taking a deep dive into some bits that may have passed you by.

MTV News contacted Singer by phone and laid his commentary over the existing trailer (shown above). He had previously stated that this first footage is more of a "character piece" than a full-length trailer, so, that said, what secrets do these characters hold?

'X-Men: Days of Future Past' is based on Chris Claremont's classic storyline, which sees Kitty Pryde traveling back in time to prevent her apocalyptic future and save mutantkind. In the film version, it's Wolverine (Hugh Jackman) who does the traveling and meets up with the 'First Class' generation of X-Men in the '70s.

"Most of the picture takes place in 1973, but in the third act, you go back and forth," says Singer. "I've created a way where parallel action can take place, so you'll be living with the characters in the future as well as in the past. ... There's an event. The movie is gearing towards this one event, and things go terribly wrong."

In addition to the original 'X-Men' trilogy players and the 'First Class' crew, Singer has introduced a few new mutants into the story, as seen in the trailer, he refers to as "a younger group of surviving refugees in the future that have been living moment to moment just trying to stay alive." While he wouldn't specifically name them, Omar Sy stated at Comic-Con 2013 that he's playing Bishop ...

Adam Canto previously confirmed he's playing Sunspot...

And Booboo Stewart and Fan Bingbing are playing Warpath and Blink, respectively.
