Brad Pitt Says He And Angelina Jolie Don't Know If They're Finished Having Kids

On-screen, Brad Pitt is no stranger to fighting. He's played an assassin, a Nazi killer -- and then there was that club.

But in real life, the dad of six says the only thing that he "gets hot about... ready to fight about," is how much he worries about his kids and how they're growing up being followed by cameras, he told Australia's 60 Minutes.

"It's a trade-off, like anything. There's a great trade-off. And we, these guys, I'm so happy for them, because they get to see the world. And their lives are so enriched by it. The privacy issues are something we're always battling."

There might be more worry in the future. Pitt says he's not sure if he and partner Angelina Jolie are done having kids. He enjoys the chaos.

"Sleep is a foregone conclusion in our home," he jokes.

Being a parent hasn't only left him sleep-deprived. The dad role has informed his work too. Pitt says:

"If I'm choosing a film now, I want it to be maybe less immature than things I have done in the past. I'm very conscious, when they're adults I want it to mean something to them. I want them to think, 'Dad's alright.'"
