The Hollywood live-action film version of the famous work by Japanese manga artist Akira Toriyama, "Dragon Ball," is produced by 20th Century Fox with Stephen Chow serving as a producer, and Jackie Chan playing the role of Master Roshi (also known as "Turtle Hermit"). The movie is directed and written by Chinese-American director James Wong (Wong Yi Yu).
The plot of the film version of "Dragon Ball" tells the story of Son Goku, who embarks on a journey to find Master Roshi and collect the seven Dragon Balls to prevent the evil Piccolo Daimao from taking over the world. This journey was entrusted to him by his dying grandfather, Gohan. Along the way, Goku meets Bulma, and with the help of her Dragon Radar, they manage to find one Dragon Ball after another. When Goku finally finds Master Roshi, they end up in a fierce fight.
Roshi recognizes Goku's martial arts style and discovers that he is actually Gohan's grandson, with Gohan being one of his former students. Goku then undergoes rigorous training under Master Roshi. After a long journey, Goku finally approaches the evil Piccolo Daimao.
