Bruce Lee

Founded Jeet Kune Do, a hybrid martial-arts philosophy combining elements of Wing Chun, boxing, and fencing with Zen Buddhist and Taoist principles, built around practicality, directness, and adaptability rather than the fixed forms of traditional styles.

Starred in and helped shape The Big Boss (1971), Fist of Fury (1972), Way of the Dragon (1972), and Enter the Dragon (1973), establishing himself as the first global Chinese film star and shifting martial-arts film choreography toward realistic, direct movement rather than fantastical staging.

Raised in Hong Kong from infancy, Lee took part in street fighting as a teenager and won the Hong Kong Crown Colony Cha-Cha Championship in 1958, before training in Wing Chun under Ip Man from 1953 to 1957 — a period marked, per the record, by tension over the traditional rule against teaching students of mixed or non-Chinese heritage.

In 1964, Lee took part in a private match with fellow martial artist Wong Jack-Man; the two sides describe it inconsistently — Lee's supporters say he won decisively in about three minutes, while Wong described a 20-25 minute inconclusive bout ending only when Lee tired. Whatever its precise course, the experience is reported to have prompted Lee to move away from rigid classical technique.

Lee was reportedly passed over for the lead role in the Kung Fu television series — a concept he had pitched himself in 1971 — reportedly over ethnicity and accent concerns in Hollywood casting. On producer Fred Weintraub's advice to build his own showcase film instead, he returned to Hong Kong and starred in The Big Boss, Fist of Fury, and Way of the Dragon; that run of box-office success gave him the leverage for Enter the Dragon, the first US-Hong Kong co-production, which shifted his career from seeking roles inside the Hollywood studio system to building an international audience through his own films.
