Hugh Jackman says he doesn't "believe in stagnation."
The 46-year-old actor, who has daughter Ava, nine, and son Oscar, 14, with wife Deborra-Lee Furness, admits he is constantly pushing himself to be a better actor and in better shape.
The 'Chappie' star said: "I don't believe in stagnation. People say they try to maintain the status quo. But I believe the natural cycle means you're either advancing and getting closer to something or you're receding."
The Australian 'X-Men' star credits 'Birdman' star Michael Keaton, who is nominated for Best Actor at the Oscars this Sunday (22.02.15), for inspiring him to believe he can continue to play Wolverine until he dies.
He told Cigar Aficionado magazine: "I always want to be in better shape than I was for the last one. Every time I play Wolverine I want to go further, physically and emotionally. I said to my wife, 'The moral is that I should never stop playing Wolverine. I've got to find a way to keep playing him until I die.' I know that someday they'll recast the role with another actor...I'd be happy if the role was eventually recast. It would mean that it had become iconic."
The 'Les Miserables' star, who frequently stars on Broadway, has avoid getting typecast in Hollywood and says he tries "to get by by saying yes to things."
He added: "I respond to what comes my way. If you asked me which plays or musicals I'd like to do, well, I know there are lots of them but what's next? I have no idea what it is."
