X-Men: Days of Future Past is not only one of the most anticipated superhero movies in the foreseeable future, it’s also an experiment in what’s to come for world building cinematic universes. Marvel had hopes that The Avengers would soar financially but even they failed to see just how successful their franchise would become. After essentially using their standalone films to promote an eventual team-up movie, interest in seeing separate films eventually come together is a market essentially untapped. Since the one-piece-at-a-time tactic has not been the explicit approach for Days of Future Past, director Bryan Singer and Fox Studios are living in a bit of a Petri dish for all to see if their approach to building a cinematic universe on the fly is a box-office success or a flop. If this first trailer, and the internet’s stunned reaction, is any indication, I’d say we’re looking at a winner.

Although this first look is notably light on action set pieces, it properly outlines the very basics of the plot – a time traveling Wolverine must warn 1970s versions of Magneto and Professor X of a coming disaster involving mutant slaying robots. But instead of selling us on the spectacle, it mostly functioning on an emotional, nostalgic level. Stirring our nerdy desire to see the characters from the past six X-Men films share the screen, Days of Future Past looks to fulfill that promise of culmination, or, at the very least, suggest that we have lift off. 

One narrative issue that the trailer suggests is that characters of the future and the past may not share many physical scenes. At least, that appears to be the case for the time being. If that approach is doubled in the film, with each set of characters condoned off into their own “present,” thusly not interacting together as a whole X-Men collective, then the promise of team-ups could come off as deceptive and insincere.

The more likely scenario is that Fox and its constituents are not going to blow that revelatory reunion moment on this first run of a trailer. If anything, it’s a trial run to gauge reaction to the concept. But if the film does end up jumping between narratives of past and present, us audience members might not be getting quite what we want. While keeping the stories largely separate could just work, it does set up a potentially disjointed narrative while also squandering the excitement of having all these actors share the same screen. If Wolverine proves to be the only connective tissue between the two subsets of X-folk, the whole trend towards character acceleration – the propulsion towards more, more, more – may prove to be too little, too late. 

X-Men: Days of Future Past is directed by Bryan Singer and stars Patrick Stewart, James McAvoy, Ian McKellen, Michael Fassbender, Jennifer Lawrence, Halle Berry, Nicholas Hoult, Peter Dinklage, Ellen Page, Anna Paquin, Shaun Ashmore, Omar Sy and Evan Peters. It hits theaters on May 23, 2014.
