Brad Pitt has revealed that despite the pressures of raising four children with Angelina Jolie, he could take even more responsibility.

The Troy star - who made the headlines yesterday for withdrawing from political drama State of Play - has said he'd like even more children, even though he already has adopted children Maddox, Pax and Zahara, as well as biological daughter Shiloh Nouvel to look after.

Talking to Weekend magazine, the 43-year-old actor said: "I want as many children as I can handle.

"Fatherhood is my greatest role yet," he added. "This is the most fun I've ever had."

And though tabloid rumours of hiccups in his relationship with Tomb Raider star Jolie have persisted, Pitt insisted the pair are blissfully content together.

"Angelina is the most wonderful woman I've known," he explained. "The children are the joy of my life and I feel as if I have been made into a new person.

"Now I am happy. And I have Angelina to thank for that."

The actor's exit from State of Play was confirmed yesterday, with the multiple script rewrites during Universal's adaptation of Paul Abbott's BBC series thought to have sparked his departure.

Pitt was due to reunite with his Fight Club co-star Edward Norton in the drama directed by Last King of Scotland helmer Kevin Macdonald, which also features Dame Helen Mirren, Rachel McAdams, Jason Bateman and Robin Wright Penn.
