Bruce Lee was one of the most successful movie box-office attractions of all time. Some would also call him the greatest fighter of his (and maybe of all) time. While almost everyone knows something about Bruce Lee, here are a few things you may not have known. His father was a highly celebrated actor in China, both on stage and in the movies. Bruce began acting in movies at the age of four. At the age of twelve, having made several movies, he starred in "The Little Dragon". This was the catalyst that sparked his martial art training. In it, he played a punk that cleaned up the street gangs in Hong Kong. The few martial arts moves he had been taught for the stunt scenes was all Bruce knew about fighting. That role made him the target of many street toughs. Out of self-preservation, he joined a gang himself, where he met a young man named William Cheung. Cheung, already a student of Yip Man for over a year, introduced Bruce Lee to Yip Man. Thus began Bruce's formal training in the martial arts. He was a dedicated student and quickly developed his skills to surpass most of Yip's students. Having little humility, he refused to exhibit traditional respect for his Sihings (elder students). The elder students approached Yip Man and used the fact that Bruce Lee was not 100% Chinese to force him out of the school. Traditionally, it was forbidden to teach kung fu to any student who was not full Chinese. Despite this, Bruce slipped back to Yip's apartment for late-night, clandestine training sessions. He continued to train with William Cheung and they began testing their skills by challenging and accepting challenges from street fighters.
