Hugh Jackman told Digital Spy that “Logan” exists outside the “X-Men” universe.
“When you see the full movie you’ll understand,Not only is it different in terms of timeline and tone, it’s a slightly different universe. It’s actually a different paradigm and that will become clear.”
“We wanted to make something really different. Definitely tonally different, early on we had the idea for the title not having anything to do with Wolverine in it but just being about the man. And what the collateral damage of being Wolverine your entire life would be.”
