Hugh Jackman is aiming for a Mike Tyson look as he bulks up to reprise his role as Wolverine.
Director Darren Aronofsky wants the Australian actor to pile on pounds in preparation for his superhero part in The Wolverine, so Hugh is taking inspiration from the heavyweight boxing champion.
"He's thick and it's chunky and it's powerful - I always think of Mike Tyson when he first came on the scene," he told the LA Times.
"Sometimes, he was a full foot shorter than his opponents and bent over [with this] massive build. There's real power. You said bulldog, and that's it exactly. Exactly. That's what I'm going for..."
Hugh has been following an intense diet for his part in the X-Men Origins: Wolverine follow-up, following Darren's request that Wolverine would be "powerful, stocky... short and thick" this time around.
"It's 6,000 calories a day, it's rough," he continued.
"I don't know how much I want to give away about it, but 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.'"
The Wolverine, which Darren said is a "one-off" and not a sequel, is expected to start filming in New York in March before moving to Japan.
