Jim Kelly...the '70s karate movie superstar, not the Buffalo Bills quarterback...died this weekend of cancer.  He was 67 years old.

Kelly was a martial artist who got his big break co-starring with Bruce Lee in the 1973 classic "Enter the Dragon".  But his place in our hearts was assured the following year when he starred in his own flick, "Black Belt Jones".

He later became a tennis pro and in 2004, he appeared in a Nike commercial with LeBron James.

Here's the "Black Belt Jones" trailer:
