According to the The British Board of Film Classification (BBFC) the first trailer for X-Men: Days of Future Past has been approved and should be hitting sometime over the upcoming weeks. With Thor: The Dark World opening on October 30th in the UK I imagine 20th Century Fox will be aiming to show the trailer before the Marvel sequel. It’s the ideal audience after all.
The X-Men: Days of Future Past trailer will probably show up online beforehand so keep your eyes peeled.
X-Men: Days of Future Past stars Hugh Jackman, Halle Berry, Jennifer Lawrence, Michael Fassbender, James McAvoy, Peter Dinklage, Nicholas Hoult, Shawn Ashmore, Ellen Page, Patrick Stewart, Ian McKellen, Anna Paquin, Daniel Cudmore, and Omar Sy. Post-production is currently under-way and 20th Century Fox has set a May 2014 release.
