He revealed that he spent an hour-and-a-half every day in training to get the buff body he showcases in the movie, and getting there took a super-mindset.

"I work out imagining I'm Wolverine," he said. "Wolverine to me is the guy that when everybody else quits, that's where he begins. I think that's why people love him."

The product of his work is evident on screen – and at home.
"At first [my wife] was like, 'Hugh, this is ridiculous, look at you,'" he said.
"'I don't know who you are – now get into bed,'" he continued, laughing.
"X-Men Origins: Wolverine" is due in theaters May 1.
