Star Runner (Chinese: 少年阿虎), (also known in the United States as The Kumite), is a 2003 Hong Kong action/romance film co-written and directed by Daniel Lee.

Bond Cheung (Vanness Wu) is a high school student in Hong Kong who has a strong passion for Muay Thai kick boxing.

He trains at a local boxing gym, and is instructed by the Kong Ching team trainer Lau (Gordon Liu), in an effort to be a competitor in the Star Runner Pan Asian Martial Arts Competition.

Then abruptly, Bond is kicked off the Kong Ching team, regarding with his coach's financial troubles, which angers him and believes that his chance in entering the competition is gone.

After some compensation, Bill teaches Bond Chinese Kung Fu (Wing Chun, Hong Kuen) as alternative and effective fighting techniques to his kick boxing.
