Wolverine star Hugh Jackman has revealed he will continue to play the role of the iconic X-Men mutant for as long as his fans demand his presence.

"I've been around long enough in this business to know great parts like this don't come along very often and as long as the part continues to grow and the reason for doing is there and that continues to grow, and let's face it, that the audience still wants to see it, I don't see any reason to give it up. I'm having more fun now than ever," the 44-year-old Australian actor confessed.

Jackman, who was nominated for an Oscar earlier this year (Best Performance by an Actor in a Leading Role for Les Misérables), also said the physical training for the character was particularly hard for this film.

Consequently, he admitted there would be a time when the physical demands of the character would necessitate a younger man. However, he stressed he would have no problem either letting go when the time came or watching someone else take on the role.

"You have to be realistic and know that these characters who have been around a long time. No one playing Hamlet is upset if someone else gives it a go," he explained.

Meanwhile, Jackman also joked that his wife, Deborra-Lee Furness, was not a particular admirer of his toned physique.

"I get a hard time for it. Deb tells me, 'Your job, as my husband, is to be fat and chubby, so that I look great,'" he bantered. And, for her part, she believes a starving Hugh Jackman is a furious Hugh Jackman.

"I think that's where he finds his rage [for the character] - you don't give him nice food ... really scary! He's really scary with no food. Wolverine rage! It takes a lot of discipline. I'm there to witness it. The world's most disciplined man," she joked in turn.

And it is not over. After having completed Wolverine, Jackman is now working on X-Men: Days of Future Past, which is set to begin filming in 2014.
