I saw this dodgy pseudo documentary under the title YOUNG BRUCE LEE: THE LITTLE DRAGON. I see that it's variously called THE REAL BRUCE LEE as well as about half a dozen repackaged titles. The year of release wasn't 1973 but rather the late '70s, either 1977 or 1979, although the finished product is so low budget and obscure that it's difficult to tell much about it.
In any case, this is an ultimate 'Bruceploitation' movie; a look behind the scenes at Bruce Lee's life which basically consists of two elements: footage from movies that Lee made as a child actor, and clips from films featuring Bruce Lee imitators which pretend to be the real deal. Both elements are uninteresting; I've seen the clips of Bruce as a child actor in other, better documentaries (you know, ones that actually had narration and context) while the other bits simply consist of Bruce Li or Dragon Lee training in gardens and beating up random people. It's a pointless, plot less affair, and one I found that tested the patience to the ultimate.
