Los Angeles, Oct 22 (IANS): Actor Brad Pitt is “surprised” by how much marriage has changed his relationship with wife Angelina Jolie. He now feels "real depth of commitment".

The couple, who raises six children -- Maddox, Pax, Zahara, Shiloh and twins Knox and Vivienne - tied the knot in August after being together for nine years.

Even though the “Fury” star didn't expect things to feel any different, he says the ceremony has changed how he feels about his family, reports femalefirst.co.uk.

“We have six kids so we felt beyond marriage already, but the kids were asking and we thought it would be a lovely thing to do, for them and for us as a family and it was all of that,” the actor told Hello magazine.

"But I was surprised afterwards at the effect getting married has had on us - it was more than just a ceremony, it meant a real depth of commitment. I feel like a married man - I really do," he added.

Although Pitt is 12 years older than his wife, the actor insists that they don't notice the age difference.

Pitt said: "We're probably around the same age maturity-wise - that's the way it works with men and women right? ... But I don't feel any different from having turned 50. I've never been one of those guys who counts time or thinks about the five-year plan or the 10-year plan.

"I'm pretty clear about how I want to live my life and what I want for my family and my wife and kids and that determines how I feel."
