SPOILER: There is a scene in the closing credits: as Wolverine enters an airport security check, he comes face to face with Magneto and Professor X, who request his assistance for a new threat to mutants. This leads into X-Men: Days of Future Past (2014).
This is the first X-Film to not have the title in the opening; it appears at the end of the film.
In the closing credits, the names of all the Japanese crew members who worked on the film are given almost exclusively in Japanese characters.
Rounded-rectangle encompassed full-screen credit: "The making and authorized distribution of this film supported over 15,000 jobs and involved hundreds of thousands of work hours."
