NOT the same person as Jimmy Wang Yu - although they two actors are quite similar in appearance.
Shaw Brothers was the professional home of Wang Yu (b. 1955) from his late teen years til age 30. In 1972 he was selected for the studio's acting training course, and upon graduation was given a supporting role in Facets of Love (1973). His first lead was the precocious teenage hero of Thirteen (1973) and he fulfilled many a teenager's dream when he was cast as Jenny Hu's young lover in Young Passion (1974). He achieved true stardom with The Spiritual Boxer (1975) and thereafter was featured primarily in martial arts films. Wang made approximately thirty films at Shaw Brothers, concluding with The Young Vagabond (1985). He gradually quit the film business after the contract expired with Shaw Brothers and he was involved in various business pursuits. He also has occasional roles, including a part in the television series Legend of the Warring States (1996). His own personal favorites from his Shaw Brothers years are The Spiritual Boxer and The Kid With a Tattoo (1980).
