Better get your fill of Brad Pitt in the next few years, because after that he’s retiring. Asked last night on Australia’s 60 Minutes how much longer he wants to act, he replied, “Three years.” After that, “Hell if I know” what he’ll do, he continued. “Hell if I know. 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 time otherwise.”
