WARNING: The following article contains spoilers for "Logan," in theaters now.

As fans learned in a January trailer for "Logan," the film takes a metatextual approach to franchise continuity, revealed the in-world existence of "X-Men" comics, which take some liberties with the team's adventures. “Maybe a quarter of it happened, and not like this," Hugh Jackman's Logan tells young Laura. "In the real world, people die.” The creation of Marvel Comics veteran Dan Panosian and Marvel Chief Creative Officer Joe Quesada, the comics offer a classic take on the mutants.

Now, with the release of "Logan," Panosian has shared an unused cover illustration, which he reveals didn't make it into the film because the "X-Men looked a little too much like the published X-Men."

Panosian is no stranger to the world of X-Men, having worked on such Marvel titles as "Wolverine," "Astonishing X-Men," "Uncanny X-Men," "Magneto" and "Alpha Flight."

In "Logan," Laura Kinney's comic books play a key role, as they serve as a map of sorts to a rendezvous point for the children that escaped from Alkali Transigen, the facility that used mutant DNA to try and breed mutant soldiers. Additionally, those familiar with the "X-Men" films will likely remember Alkali Lake as the name of the military complex where William Stryker housed the Weapon X project that initially bonded the adamantium to Wolverine's skeleton.

Directed by James Mangold, the film stars Hugh Jackman, Patrick Stewart, Boyd Holbrook, Richard E. Grant, Dafne Keen and Stephen Merchant. "Logan" is in theaters nationwide.
