Perhaps Angelina Jolie and fatherhood have had a sobering effect on Brad Pitt. He was quite the colorful character in his days escorting the likes of Gwyneth Paltrow, model Jitka Pohlodek and ex-wife Jennifer Aniston to red carpet events. But ever since he and Angelina linked up, Brad's worn black to just about every important film premiere. From the more formal black suit and tie pairing he sported at the New York premiere of A Mighty Heart last night to the chic black Henley under his dark jacket at the Ocean's Thirteen premiere in LA, Brad looks like a man who means business these days.
