The Wolverine has long been rumored to contain a post-credit stinger that reveals Patrick Stewart as Professor X coming to retrieve Logan at the airport, which will lead directly into the release of next summer's X-Men: Days of Future Past. While director James Mangold doesn't deny this, he wants to make it clear to fans who might be disappointed come opening night that the two films have nothing in common, and are not tied together in any way. As stated before, The Wolverine takes place years after every movie in the franchise, including X-Men: Days of Future Past, at a time when all of the Mutants we now know are dead and buried.
That said, its likely that there will still be a post credit stinger. It's just that the two films will not be tied together within their story structure, and like we see with some of the Jean Grey footage, this rumored cookie will serve as a flashback.
The Wolverine was released July 26th, 2013 and stars Hugh Jackman, Tao Okamoto, Rila Fukushima, Hiroyuki Sanada, Svetlana Khodchenkova, Brian Tee, Hal Yamanouchi, Will Yun Lee. The film is directed by James Mangold.
