Fist of Fury stars Bruce Lee as Chen Zhen, an angry young man who possesses a dangerous punch called the "fist of fury". Once he's in fighting mode, the kid can't stop. Arriving at the Jing Wu school he sees the burial of his master, unable to control his violent rage one of the teachers hits Chen over the head to knock him out which sets the pace for the rest of the film. The Jing Wu school is constantly being harassed and bullied by a local Japanese karate school. During the time period the film was set in, Shanghai was under foreign occupation and the Chinese people were treated like second class citizens in their own country, The constant bullying by the Japanese, led by their wormy translator Wu (Paul Wei) sets off Chen and his raging "Fist of Fury".
The movie was another huge success for Bruce Lee who now had the freedom to become his own director. His constant butting of heads with Lo Wei, the want to create movies that will appeal to a wider Asian and International audience (I guess the film was kind of hard to market in Japan) led to the production of Way of the Dragon, more more light hearted action film (well, compared to Fist of Fury and The Big Boss). The film was remade several times, parodied by Stephen Chow and was made into a TV series in Hong Kong.
If you're a fan of kung-fu films then you'll want to make sure Fist of Fury is on your list.
