Hugh Jackman Eating 6,000 Calories A Day For 'Wolverine' Role

Darren Aronofsky sure makes weighty demands of his actors.

The Oscar-nominated director had Natalie Portman and Mila Kunis lose big weight for their ballet drama 'Black Swan,' and now that he's taking the helm of the next 'X-Men' movie, 'The Wolverine,' he's making star Hugh Jackman gain major weight.

"Darren said with the last one, 'Hey you looked great, but you're so tall that in those long shots you looked kind of like Clint Eastwood, and that's not Wolverine,'" Jackman told the Los Angeles Times. "He said that Wolverine, in the comics, is powerful, stocky...he's short and thick. So he said, 'I want you to go there, get bigger.'"

Jackman has played Wolverine in four films already, and often played him lankier than the comic portrays the mutant superhero, a sturdy, hardened warrior.

Back in December, Aronofsky spoke to MTV about his attraction to the project, which in large part was due to Jackman.
