The Sundance Film Festival in Utah may be ending this Sunday, but that's not stopping the celebs, who are turning up in their droves. So who have we spotted over the last 24 hours, apart from the already mentioned Mischa Barton and Adrian Grenier. Well, best snap of the day goes to Charlize Theron, who sizzled her way through the crowds of waiting fans. Her cute hat perched perfectly on her chic bob, as she warmly sighned autographs in a stunning pair of black high heeled boots. (Did she not see the wheather forecast?). Also spotted giving Splash News a wave: The Edge and Bono of the band U2, poser Paris Hilton, hunky Josh Hartnett and actor Denis Hopper.
