The Wolverine

Hugh Jackman said that for his shirtless scenes in this movie, he wanted to look "as ripped and cut as possible." So he adopted a dehydration diet (used in bodybuilding) where he did not consume any liquid for thirty-six hours before filming his shirtless shots. He said it made him feel "headachy" and faint, but he was pleased with the results, as dehydrating tightened everything up, and gave him the exaggerated muscle definition and vascularity that he wanted to show in his shirtless scenes.

(at around 1h 24 mins) When Logan is pulling the X-ray machine up his body, an X-ray of his legs is shown. In this X-ray, he has no knee caps.

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).

Also available in a 3D version.

Edited into X-Men: Apocalypse (2016)
