Just saw this and I think it is a great way to create extra hype around a movie.
X-men: Days of Future Past is a famous story line from the comic books and with the release of Wolverine last week, Marvel are once again dominating movie theatres.
Last year with Batman, this ploy was used with the trailer showing a whole 5 minutes of the film and this helped generate a lot of hype. So like sheep- let's follow and definitely believe the hype.
Check out this video by Macklemore & Ryan Lewis. One love.
