This film tells about, and shows clips of his early work. There was a T.V. show called "Longstreet" from 1969 that has lots of Bruce in it. clips from that episode are included in "Bruce Lee: A Warrior's Journey (2000)".
NOTE: The S.E. 2 DVD SET of "Enter The Dragon" has "Bruce Lee: A Warrior's Journey (2000)" as a bonus!

I think that Bruce Lee was the best Kung-Fu presence in films. He had that balance of fighting style, and pure "Cool" on camera.
I think that "Game of Death" should be saved as your last viewing. "Bruce Lee: A Warrior's Journey (2000)" is the best way to see the footage that Bruce had shot for that unfinished project.
Look out for two "Game of Death" related "Bruceploitation" films called "G.O.D. Storyline" and "Bruce Lee in G.O.D." These titles make the films sound the same, but they are not. The first title uses a new actor to play Bruce's character Billy Lo, and along with narration gives a visual walk through of the known (but unused) plot that Bruce had intended for his "Game of Death" project. They also use the original Bruce Lee directed pagoda footage (with alternate music) that is shown in "Bruce Lee: A Warrior's Journey (2000)".
The film "Bruce Lee in G.O.D." is more of a "Making of" story. It has actors playing Bruce Lee, Ramond Chow (The Producer of the Lee films), Linda Lee, and other important people who made "Game of Death" back in the early 70's. It tells the story of Bruce filming the movie, and has some footage from the Lee directed "Game of Death" spliced in too.
"Game of Death II (1981)" does not include much at all! If you have the S.E. DVD of "Enter the Dragon", then you have seen the footage that was spliced into "Game of Death II (1981)". The footage that was spliced into this film are the scenes originally cut from American prints, and one scene that was not in the original international release. All that deleted footage was restored on the S.E. DVD.
"Game of Death II (1981)" is worth watching, and is better then part 1. But don't expect to get blown away by any Bruce footage. The commentary track on the import "Game of Death II (1981)" DVD is very good, and worth seeking out!
WARNING! "Goodbye Bruce Lee: His Last Game of Death" is the worst "Bruceploitation" DVD I have seen. It looks like it was shot on Super 8 film, and is a "lower end" Bruce Li project.
The best looking collected set of Bruce Lee films (I have seen) is the 6 DVD 30th Anniversary Commemorative Edition set from Hong Kong legends. This set is Region 2. This set does not include "Enter The Dragon" due to it being owned by Warner Bros.

Also look for the documentaries "The Legend" and "The Man and the Legend" these two documentaries have great footage and info, and are a must for a fan. They are on the same DVD as a two-fer if you get the Region 2 disc.
Hope this helps you..
