A leaked trailer for Bryan Singer’s X-Men: Days of Future Past is currently making the rounds online.

Although 20th Century Fox has worked overtime trying to take down the clips as fast as they’re uploaded, the footage just keeps coming back around. Although you can find wo of the trailers embedded below, there’s really no way of knowing how long they’re going to last.

Like the leaked Grudge Match and The Amazing Spider-Man 2 clips, you should enjoy the X-Men: Days of Future Past trailer while you can. The quality may not be the best you’ve ever seen, but it’s still interesting to see Singer’s sequel in action.

Instead of relying on huge action set-pieces to set the stage, the director opts for something a bit more dramatic. Patrick Stewart’s Professor Xavier narrates the clip, which finds all of the mutant superheroes making an appearance. It’s good to see some of them back in action.

The leaked X-Men: Days of Future Past trailer arrives courtesy of someone who was in attendance at this year’s Fantasia International Film Festival in Montreal. The folks at 20th Century Fox are no doubt irritated by the trailer’s unexpected and unofficial arrival.

People who attended the San Diego Comic-Con earlier this summer have noted that most of the footage found in the embedded clip was screened at the annual event. Just because you’ve seen the clip before doesn’t mean you won’t enjoy it again.

Here’s the official synopsis for the upcoming X-Men sequel. It’s not much to look at, but this is as official as it’s going to get for the moment.

The X-Men send Wolverine to the past to change a major historical event that could globally impact man and mutant kind.

Unfortunately, it would appear that 20th Century Fox has done a spectacular job of removing any traces of this leak from the internet. If you’re just now getting to this article, then I’m afraid you’re already too late.
