After 17 years, it's the end of an X-Men era. Sir Patrick Stewart, 76, plays the powerful Marvel mutant professor Charles Xavier for a seventh (and likely final) time in Logan, a third Wolverine-centered film starring Hugh Jackman opening Friday. There are only a few actors who are as respected as Stewart for his work in the X-Men franchise. When asked if Logan would be his last film as Charles Xavier Stewart says, "there could never be a better way of saying goodbye to the franchise than this film."
