I recognized the name but had to look it up. He was a very skilled kickboxer and did commenting for UFC. He also made Roger Corman-produced movies:

The worldwide success of 1988’s Bloodsport, starring Jean-Claude Van Damme, generated a resurgence in the production of martial arts films. Bloodfist was exploitation mogul Roger Corman’s entry into the genre. To find his next star, the producer instructed his staff to survey martial arts publications’ fighter rankings, where the name of Don “The Dragon” Wilson came up. Unsure if he even had the right contact information, Corman left a message on one Don Wilson’s answering machine that said “Hi, my name is Roger Corman. If you’re the Don Wilson that’s the kickboxing champ, I’d like you to come in and read for my film.”[8] Wilson had no idea who Corman was, but he did and after only reciting a handful of lines, the producer informed him he was hired.
