Hollywood heart-throb Brad Pitt said he enjoys getting older because age brings wisdom.

“Me personally, I like aging. With age comes wisdom... I’ll take wisdom over youth any day,” he told a press conference during a visit to South Korea to promote his latest film Moneyball.

“I think, certainly, being a father changed everything for me,” said the actor, 47, whose partner is fellow superstar Angelina Jolie. They have six children.

Parenthood means a changed perspective for him, an interest in taking care of himself and mornings being around for their children, he said.

Moneyball, is an adaptation of Michael Lewis’s 2003 bestseller Moneyball: The Art of Winning an Unfair Game.

Mr Pitt stars as Oakland Athletics baseball team general manager Billy Beane, who took on the big league by assembling a competent team on a shoestring budget – using a new method to evaluate players and find their hidden talent.

He said the film’s box office success elsewhere was not merely celebrity-driven.

“Popularity is good for the opening weekend but what we’ve been really happy with this film is that it keeps playing weekend after weekend, crossing generations and genders,” he said.

“And that tells us we have something more than a film, (more than) a celebrity-driven film or a subject-driven film. It’s really a good movie and it’s really fun and it’s a good laugh and it’s got meaning in it.”

Mr Pitt said he was interested in shifting from acting to the production side but was not putting an exact time limit on his acting career.

During an interview with an Australian current affairs show in Tokyo, he had said he would quit acting at 50.
