The comic storyline by that name, written by Mark Millar, revolves around a wild dystopian future in an alternate Marvel universe.
In an interview with Digital Spy, Jackman revealed that, like Old Man Logan comics, Logan doesn’t necessarily share the same universe as its source material.
In this dark future, the United States has been conquered and divided by supervillains, and Wolverine has inadvertently killed the X-Men.
Not only is it different in terms of timeline and tone, it’s a slightly different universe.
