Jackie Chan will fight on the big screen again on Christmas Eve. In Police Story 2013, he plays a veteran cop who is able to handle brutal criminals but became helpless before his rebellious daughter. With his clout, one scene was allowed to be shot in the Beijing subway. That was the first time the real subway was used as a set in a film. In addition to intense action sequences, Chan also shows his music talent by singing the theme song, based on mainland pop singer Sun Nan's hit song Save.
