Christy Chung had it worse while filming The Incredible Truth -- she had to lie in the middle of a field covered in bird poop.Sam Lee plays a serious Japanese cop in the film and had many scenes with Christy Chung. According to a report on hktopten.blogspot.sg, Christy revealed that her most memorable scene was a heroic rescue. "That day the ground had a lot of bird feces, when I lay on the ground it really stank. Luckily the crew worried about bird flu and tried to coordinate with camera angles as much as they could. After every shot they would prepare alcohol for hand washing and clothing cleaning," she said.
