But X-Men stalwart insists that he's cool with the idea of someone else playing the mutant he made famous...
Hugh Jackman has been discussing the possibility of being replaced by a younger actor in the role of Wolverine.
The Aussie hunk, now 45, has been playing the adamantium-clawed mutant since the first X-Men movie in 2000, and has also appeared in two spin-offs based on the character.
But he has told IGN that he reckons 20th Century Fox have already started talking about replacing him.
"I'm sure they had the discussion," he admitted. "They didn't mention it to me, obviously!
"Look, that's inevitable, man. Anyone who thinks they're indispensable in this business is fooling themselves. But I feel unbelievably blessed to have this part. I never thought in a million years I'd get to play him seven times.
"Every day I walk on the set with the claws and the hair, I thank my lucky stars. I don't take any of it for granted. To think that in a second version we'd have this cast and this director, and you guys don't know the script, but I would say probably the best script of all of them, is pretty amazing.
"I think that's why I'm still here. I'm sure by the way, that it won't always be my decision to always be here. At some point, someone will close the door on me."
Jackman will be seen playing Wolverine again in X-Men: Days Of Future Past - which hits UK cinemas on 22 May.
