Could this be the year that Bruce Willis is the key to cinematic universes? M. Night Shyamalan recently announced that he would be making a crossover sequel for both Unbreakable and this year’s Split, and with Luc Besson’s upcoming sci-fi film Valerian and the City of a Thousand Planets about to hit theaters, more than a few people  —  myself included  —  have wondered if Valerian would make any passing references to Besson’s The Fifth Element. Another small cameo by Bruce Willis at the end, and suddenly he’s the man holding two separate franchises together.

This is all speculation of course, but one of the watchful eyes at /Film recently noticed something in the new Valerian poster that might suggest more shared cinematic universes are on their way. Let’s get a good look at the poster first:

Got it? Now, in the top right corner of the poster, you might see the name ‘-orben’ outside a bar. /Film speculates that it could mean that Willis’ Korben Dallas  —  his special forces operative turned taxi driver turned savior of the galaxy  —  might have a surprise appearance in Besson’s film. This is all just guesswork, of course, but it’s a fun thing to make note of. Either way, the new post for Valerian is quite the beauty. Maybe we’re just suckers for lavish sci-fi punishment, but put this on the top of our list for summer 2017.

Here’s the full plot synopsis for Valerian and the City of a Thousand Planets:

Valerian and Laureline are special operatives for the government of the human territories charged with maintaining order throughout the universe. Under directive from their Commander, the two embark on a mission to the breathtaking intergalactic city of Alpha, an ever-expanding metropolis comprised of thousands of different species from all four corners of the universe. Alpha’s seventeen million inhabitants have converged over time- uniting their talents, technology and resources for the betterment of all. Unfortunately, not everyone on Alpha shares in these same objectives; in fact, unseen forces are at work, placing our race in great danger.

The film will star Dane DeHaan, Cara Delevingne, Ethan Hawke, Clive Owen, Rihanna, and Rutger Hauer. You can catch Valerian in theaters on July 21.
