Brad Pitt insists on regularly checking Angelina Jolie's Cambodian property for mines, despite her assurances the grounds are perfectly safe to walk on. Jolie has already cleared the 230 square mile area, which was previously covered in mines left by the Khmer Rouge in the late '70s, and installed night-vision cameras - but Pitt still worries. She tells American magazine Esquire, "Brad doesn't get angry with me. He just gets concerned. "He's much more - well, maybe he's smarter about it. The attitude being, 'Let's not just be walking around here, let's be cautious in a healthy way.' "I'm brave to the point of stupidity sometimes. He's asking if the property can be de-mined again."
