It’s been confirmed more than once that Black Swan helmer Darren Aronofsky will direct Hugh Jackman in the X-Men Origins sequel, The Wolverine. Now that we’ve got that out of the way, it’s time to get down to business. Jackman recently spoke with Entertainment Weekly, and revealed some of the preparation he’s doing to get back into Wolverine shape.

One of the first orders of business that Aronofsky wanted take on was forcing Jackman to put on weight. This isn’t anything new for the actor, because he’s done it four times in the past but the director wanted him to take it a step further. He told him to aim for 25 pounds of muscle, which is more weight than he’s ever gained before. “It’s not easy for me,” Jackman says. “Because I’m actually quite long and lean.”

To help him out with this problem Jackman called up Dwayne Johnson who previously put on 25 pounds for his role in Faster. Do you want to know what he told him? “Six months, a pound a week, 6,000 calories a day which, Jackman points out, is an awful lot of chicken, steak, and brown rice.” It sounds exhausting but the end product will get us a bigger, more ferocious Wolverine.

Do you think 25 pounds is too much for the character?
