Wolverine was once the breakout star of the cinematic X-Men universe. Even though he never really led the X-Men, and often didn't even want to be a part of the X-Men, he somehow became more associated with the mutant superheroes than those with bigger, flashier powers. He even remained a fan favorite despite being the star of a poorly received solo movie.

But these days Wolverine is no longer the marquee attraction. The X-Men have a whole new roster of younger, fresh faces to push, and it looks like Wolverine is back to being a loner after X-Men: Apocalypse. Hugh Jackman's third, and reportedly final, solo Wolverine movie has just begun filming, and so producer Simon Kinberg has decided to confirm a few rumors:

- It's like a violent Western.

- It's going to be R rated.

- It will be set in the future.

Most fans will probably freak out at the idea that they're finally going to see Wolverine do the bodily damage those claws are capable of, but the R rating isn't the most interesting news here. The movie being set in the future likely means we're seeing some version of the "Old Man Logan" storyline written by Mark Millar (see below). 

But the next Wolverine won't be the only new X-Men movie set in the future-- at least as far as the current chronology goes. X-Men: Apocalypse is set in the 1980s, and Kinberg confirmed that the next X-Men movie will be set in the '90s. There's a catch there, though. He didn't clarify what movie that would be.

It could be a sequel to Apocalypse, which does introduce new versions of Cyclops, Jean Grey, Storm and Nightcrawler, but that also introduces another problem. Those new actors can jump a decade and still look more or less the right age. But at that point Mystique and Beast and Professor X are all going to be older than the actual actors playing them, which is a weird timeline issue.

But Kingberg could also be talking about the New Mutants movie that Josh Boone is attached to as a writer-director. Either way, the '90s is when a whole generation first discovered the X-Men, so you can expect one of those movies to play right into the dreams of everyone who grew up on the Saturday morning cartoon.
