He passed away due to complication from cancer. He was one of my first childhood heroes. Will never forget his famous movie quotes from Enter The Dragon, RIP Mr. Kelly.
I loved the line "Bull****, Mr. Han Man." Saw him in an interview a few years back, enjoyed it. R.I.P. Kelly
To be honest I never really forgot about him but he was so humble, that a lot of his accomplishments were never really publisized, and you didn't hear much about him beyond Enter The Dragon. He had a short stint doing movies they called Blacksploitation in the 70's, but he lived a rather low key lifestyle, which was the complete opposite from his character in Enter the Dragon. One thing I found interesting is he studied under the Gracies in Brazilian Ju-jitsu, and stated in an interview that although his roots were in tradition Karate, he later on got convinced that grappling was necessary for an all around fighter.
