A memorable scene in the movie shows a woman performing oral sex on her boyfriend. "Everyone asked why it was so real. The secret is: It was all real!" said director Scud with a smile. "Linda So (playing the girlfriend) was at first concerned if she was going to be able to do it - she was. The scene took five takes to film, and Haze Leung (who played the boyfriend) quipped, 'One more take and I would have come.' When we where done, Linda and Haze collapsed in laughter. They are real professionals."
