At the age of seven, Jackie was given over to the Peking Opera School, a now defunct military-styled martial arts and opera training academy. For ten years he was systematically beaten by the stern masters at the academy (the contract for entry included an immunity clause in case the teachers killed you while training). Although brutal, this regimented lifestyle helped to hone the incredible strength and agility that Jackie is famous for.
Following his release from the opera school, a young Jackie took his martial arts and acting ability to film, getting his start as a stunt double in tons of Shaw Brothers chop-socky flicks. It was the death of Bruce Lee, and the subsequent search for a new martial arts superstar, that led to Jackie getting larger film roles.
