Brad Pitt may end acting career in 3 years

Brad Pitt's career plans may not necessarily include much more screen time, the film star said in an interview Sunday, musing that he may only remain in acting "three years" more.

And after that? "Hell if I know," Pitt, 47, told Australia's "60 Minutes" news show. "I am really enjoying the producing side and development of stories and putting those pieces together, and getting stories to the plate that might have had a tougher time otherwise," he said. "You know, I have gotten away with a few things in writing and I have been ---- off about a few things," he added, declining to answer when interviewer Tara Brown asked what some of those were.

Family -- his six children with his partner of six years, Oscar-winning actress Angelina Jolie -- has become a source of contentment, he said. "I mean, family's family, isn't it? When you're around trying to make breakfast for everyone . . . [and] those late nights are so fun when one of them's up or those mornings when they get up and make pancakes or something. That's what it's about."

Would he like more children? "Uh, you know, I don't know that we're finished," he answered. "I don't know yet. I don't know."

Pitt added that having children has changed him as an actor. "If I'm choosing a film now, I want it to be maybe less immature than things I have done in the past," he said. "I'm very conscious [that] when they're adults, I want it to mean something to them."

Even so, he said, "Happiness is overrated. . . . I think sometimes you're happy, sometimes you're not. There's too much pressure to be happy."

Pitt was in Australia to promote the opening of his latest film, "Moneyball."
