Brad Pitt has revealed fatherhood has made him a better actor - because he wants to rush home to see his children.
The 45-year-old - speaking about his new movie The Curious Case Of Benjamin Button, about a man who ages backwards - said he works faster these days, partly because he's anxious to get back to girlfriend Angelina Jolie and their six kids.
Brad told the Los Angeles Times: "Once you hit 40, you start re-examining the math of it all. I'll trade wisdom for youth any day.
"I don't have to grope as much for the character. I can get there quicker, so it's not as much trial and error.
"Also, as I get older, more experiences, I'm more fine-tuned in what I'm after, what I think speaks in the piece.
"And lastly I want to hurry and get home to my kids."
In the movie, Brad's character can only have a short time with the woman he loves - played by Cate Blanchett - when their ages overlap.
The star revealed his love for Angelina helped him understand the role better.
He said: "It's a tragedy in the sense that any love involves loss, and that's the risk you take. And the greater the love, the greater the loss. I certainly feel that now with the woman I'm with, and the children that I have. But whatever the course may be, this time together is extraordinary."
