When you're one of the biggest movie stars in the world, you have the luxury of doing pretty much whatever you want -- even if that means quitting the very business that turned you into a celebrity. In an interview with 60 Minutes Australia, Brad Pitt admitted that he is ready to quit acting by the age of 50 (he's 47 now). "[I will in] three years," he said. "I am really enjoying the producing side and development of stories and putting those pieces together. And getting stories to the plate that might have had a tougher times otherwise."
