What are ALL the diff endings of Bruce Lee's Game of Death?

So i saw Game of Death a long time ago on TV and thought it was sweet. So I buy it on DVD and the whole movie was different and the ending was TOTALLY different and kinda sucked.

I remembering watching some show that explained all the diff endings and why it happened. Can someone enlighten me on this?

I saw the same program - it was on AMC.
It was a documentary about the making of Lee's last film.
He died before it was complete so the producers tried a variety of story lines to explain why Lee and his friend were going from floor to floor fighting guys with different martial arts styles. They also tried using actors who didn't look at the camera to double for Lee in the scenes that were never shot. I think he shot all the action stuff first.
They even showed footage that wasn't color-corrected as if it was never shown before.
If I remember correctly, after (or maybe before) the documentary - they showed the actual film. Sounds like the producers tried to re-release it yet again and messed with the story.
hope this helps.
