Brad Pitt plans to expand family, take step back from movies

"We're just getting started," he was quoted by DPA as saying in an interview on CNN's

Larry King Live that aired Wednesday night in the United States.

The 43-year-old star of such movies as Babel and Ocean's Eleven described Jolie as "a fantastic mother" to their four children - Maddox, 6; Pax, 4; Zahara, 2; and Shiloh, 1, adding that while parenthood is "the hardest job in the world," "it is everything" to him.

Pitt said in the interview that acting was becoming less important to him and that he would like to spend his time on other pursuits.

"It's become less and less a focus as I get older," he said. "I think it's really more of a younger man, younger woman's game."

He said he didn't intend to give up acting - "I'd like to drop in if I'm still invited every few years or so" - but added, "It takes so much time. There's just other things I'd rather be doing."
