Sean Penn gave film fans a treat when he was spotted in London shooting his new movie.
The Hollywood star was seen filming scenes from The Gunman in the capital at the weekend, reported the Daily Mail.
Sean was snapped in costume, wearing jeans and with a large backpack, walking along Tower Bridge while a helicopter hovered overhead.
It's thought he was working on action scenes for the upcoming film, in which he plays a spy who has to clear his name to save his own life.
