London: Hollywood actor Hugh Jackman has been taking tips from former wrestler Dwayne Johnson to get back in shape for his latest `Wolverine` movie.
The `Prestige` star is set for a second outing as the `X-Men` character and has been ordered to hit the gym to become even more muscled for the sequel, a website reported.
The 42-year-old actor is finding it tough to put on 25 pounds of muscle for the role of the clawed mutant and therefore called Johnson, popularly known by the ring name `Rock` for advice.
"Twenty five pounds is more than I ever have put on for the role. It`s not easy for me. Because I`m actually quite long and lean. I had a chat with Dwayne Johnson, who did 25 pounds for his movie (Faster). I rang him up and was like, `Okay, tell me what`s going on`," said Jackman.
Jackman followed Johnson`s tips and is now consuming around 6,000 calories a day to gain the extra muscle by gorging on chicken, steak and brown rice.
