2. Fists Of Fury (1971) - How To Defeat A Dojo
There's still a lot of enmity between China and Japan due to the Japanese occupation during World War 2. So much so that this film which deals primarily with that was actually remade years later with Jet Li in the title role. But I can't help but think that this film was a way to vent the frustration that Bruce felt at the racism he experienced while living in America. In Fists Of Fury Chinese citizens are treated as second class citizens on a par with dogs (and I mean this literally; an earlier scene involved Lee destroying a sign that forbids dogs and Chinese people entering a local park). And when Bruce's sensei is poisoned by the leader of a rival Japanese dojo it looks as if they're going to get away with it. Not if Bruce has anything to say about it. In this one scene
he takes on the whole dojo, at one pointing turning two Japanese martial artists into human nunchucks. When someone does land a blow on him all it does is give Lee the momentum he needs to reach a pair of actual nunchucks. It ends with Bruce destroying the Japanese Sensei and making his students eat a scroll proclaiming their boast that Japanese karate is superior to Chinese kung-fu with the promise that "Next time it will be glass." The lesson here is never give Bruce Lee reason to take revenge on you. Just don't do it. It's just not clever.
