Details about Hugh Jackman's third and final solo film as Wolverine are pretty scarce. We know that James Mangold will return as director, following up 2013's "The Wolverine," and that the film will be written by David James Kelly. Will that script be based on "Old Man Logan"? At this point, who knows! We're not even sure if Jackman's Wolverine is gonna make an appearance in "X-Men: Apocalypse." So much about "Wolverine 3" remains a mystery, but it looks like we know one thing for certain: Patrick Stewart's back.

Patrick Stewart Confirms Role in Next "Wolverine" Film

In a recent interview, Stewart revealed that he's ready to play Professor X one more time in Jackman's final Wolverine film. "There is a project in development," said Stewart. "I understand that Professor Xavier will be making more than an appearance, however. That intrigues me."

It intrigues us, too, especially considering the lengthy history those two X-Men have in the comics. These two have been through a lot together, so -- just to get you excited about possibly seeing Jackman and Stewart together again -- we've compiled a list of the covers that Wolverine and Professor X have shared over the past 40 years. For added delight, just imagine the actors in some of these poses.
