Sexy Charlize Theron went to huge lengths to ensure the roving paparazzi didn’t get a shot of her filming her nude scenes in upcoming movie 'The Burning Pain', by shooting at the crack of dawn. Charlize get's naked for her role in the upcoming drama and is seen smoking a cigarette through an open window in full view of passers-by. But movie bosses were very worried the photographers would catch the star naked once they discovered the location of the movie shoot, so they changed the time of filming to make sure Theron’s scenes were kept top secret. Director Guillermo Arriaga tells New York Post’s gossip column PageSix,We had to shoot the scene at 6am before any of the photographers were up. It was done in such secrecy that it wasn't even in the script. Only three people, including myself, knew it was going to happen.
