Production on Mission: Impossible 5 wrapped just over a week ago and today the director Christopher McQuarrie and the film's star Tom Cruise have teased a big announcement for tomorrow.

What could it be? Could it be a trailer? A poster? A teaser for a trailer? Maybe we'll find out the film's official title? Who knows! There is so much about the film that has remained in the dark.

Light the fuse. — Tom Cruise (@TomCruise) March 21, 2015
