Pitt doesn't want to embarrass family

Brad Pitt worries his film choices could "embarrass" his family.

The 'Inglourious Basterds' actor - who raises Maddox, 11, Pax, eight, Zahara, seven, Shiloh, six, and four-year-old twins Knox and Vivienne with fiancee Angelina Jolie - admits one of the factors he prioritises when considering a new role is whether his loved ones would be proud of the work.

He said: "I want it to be worthy enough of a story to leave the family, you know? They're everything. The family is first... I also don't want to embarrass them."

Brad is just finishing work on post-apocalyptic zombie horror 'World War Z' and is confident it's a film his sons will love.

Speaking to Guy Ritchie for Interview magazine, he said: "We've got some tidying up to do there, but that one is gonna be big and entertaining. My boys are gonna love it."

Brad also admitted he always seeks to find projects that are very different to his previous movies as if he gets bored by the material, his performance suffers.

He said: "Right now, this is like a clean-up-the-loose-ends-and-tidy-up-the-place kind of year, which I also look at as a refill kind of year. I'm not good at going back-to-back-to-back-to-back with movies, and it's just now that I'm starting to get my bearings again and a flavour for what's next.

"But it can't be something repetitive that I've done before. I'm bored to death by that, and when I attempt things like that, it never works - I end up hurting the movie. So it's just about discovery now and finding something new that's interesting to me."
