The pair was joined on stage by director James Wong and actors Joon Park, Chow Yun-Fat, Jamie Chung and James Marsters.
Synopsis via Wiki: Goku (Chatwin) goes on a journey to find Master Roshi (Yun-Fat) and gather the seven mystical Dragon Balls before the evil Lord Piccolo (Marsters) can. Along his way, he meets Bulma (Rossum) who then joins him to help him in his mission. When arriving at Roshi’s place, he is not welcomed with an embrace but has to fight Roshi. Roshi soon learns that Goku is the grandson of Gohan (Duk Kim) and thus trains him to prepare him for the ultimate battle with Lord Piccolo to prevent him from collecting the powerful Dragon Balls.
