I ended up watching it.
Pretty good. It wasn't a "movie" it was a documentary, with about 40 minutes of never before seen Game of Death footage.
Hi-lites include, interviews with Linda Lee Cadwell, Taky Kimura, a decent amount of training footage (seen before), Lee fighting in a tournament wearing all sorts of protective gear...
The big thing though is the recovered Game of Death footage. I haven't seen the theatrical release of Game of Death, so I can't really compare it. From what this documentary said was, the theatrical release only included 11 minutes of fight scenes in the pagoda, including the Inosanto and Jabbar fight. This stretches to about 37-40 minutes. It's got Guro Inosanto doing more stick work on Bruce Lee's character's accomplices, their subsequent fight with a Hapkido practitioner, and a longer fight with Kareem.
Interesting stuff.
I haven't read Dragon (keep meaning too), and am a little ignorant on this subject. According to this movie, Bruce Lee was already calling his "evolved" fighting art Jeet Kune Do. But after his back injury in 1970, after reading A LOT, he came to the conclusion that styles and systems were too confining, and closed his schools. He continued teaching very small groups after that. So, if style and systems aren't "the way," what was he teaching this handful of students at this time? Or at least, what was he teaching people to start with?
