It was recently announced that the Old Man Logan film adaption was recently name, simply titled Logan. Since the announcement, we've seen a few set photos of Hugh Jackman in a significantly older appearance, as Old Man Logan takes place many years after the current age in comics.
While Wolverine is able to regenerate with his X-factor, making him appear aged, but not too old, many other characters are simply unable to do such a thing. With the setting of this film, it would make sense to see some of the few remaining X-men (NO SPOILERS for you comic book fans!) at a very advanced age. Well one such aged character may have emerged.
Enter: A very grizzled looking Sir Patrick Stewart. The very man who refuses to physically age, brought to an accelerated age with stage make up and movie magic. While the Old Man Logan comic books do not feature Professor X, the new X-Men movie series follows its own canon, so not only is the story up in the air, but so is the cast list. What other classic X-Men could be featured in Logan?
