The trailer for X-Men: Days of Future Past has arrived online and my first thought after watching it was "that wasn't what I was expecting", and it's strange as I don't really know what I was expecting, but it wasn't quite this.

Let me say upfront though, this is a superb trailer and it's way better than I was thinking it would be. Oh I expected the big names and the big effects, but I thought the story was going to be one way from everything I had read about it and this trailer has made it seem multiple times better.

Of course I'm not quite sure what I was expecting but hearing the story of the X-Men of the future having to go to the X-Men of the past, that would be the X-Men we see after the film X-Men: First Class, created one rather strong image in my mind.

That image didn't come to life in the new trailer and what we get is something more personal to the X-Men we already know, something that ties the old and the new and brings a dramatic story to the core.

I think part of my concerns were that X-Men: Days of Future Past was going to become too big a science fiction story and not stay focussed on the story and the characters, not so.

Here we're seeing the Professor X, Magneto and Wolverine of Patrick Stewart, Ian McKellen and Hugh Jackman seemingly working together to send Wolverine back to his younger self to meet the younger X-Men, with James McAvoy and Michael Fassbender and others returning, in the past and avert a disaster in the future.

While doing so we see that the Xavier of the past isn't the calm and strong willed man that we've seen and he may perhaps be as mentally broken as his physical body was.

The teaser is superb and The Hollywood Reporter points out that Bryan Singer has already tweeted that this trailer would be more character based as the special effects work has still to be completed. I think this is all the better for it.
