The ageless Wolverine is once again portrayed by the ageless Hugh Jackman (seriously, go back and look at Hugh in the original X-Men ... he looks exactly the same). Jackman is also the only actor to appear in every X-Men movie to date. This is the second film focused primarily on this character, and while the first, X-Men Origins: Wolverine, discusses how Logan became who he is now, this film acts as an update on the titular character after the original trilogy. SPOILER ALERT - THIS FILM GIVES AWAY IMPORTANT PLOT POINTS FROM THE ORIGINAL TRILOGY. WATCH THE FIRST THREE FILMS BEFORE WATCHING THIS ONE. Following the completion of the first three films, Logan goes into hiding in Alaska, haunted by many events in his past. While there, he is found by a Japanese girl who was sent by Yashida, an old Japanese man Logan had saved from the Nagasaki bombing in World War II. Yashida became a wildly successful businessman, but is now on his death bed and wanted to say goodbye to the man he owes his life to. So Logan flies to Japan and learns there is a way to reverse the effects of his mutation, stop healing, and eventually grow old and die in peace. Unsure if he wants to go through with it, the situation is forced on him by the villain (another mutant). Logan is then forced into action without being able to heal as he is used to doing while protecting Yashida's granddaughter from a clan of ninjas.
