Many of you are misinformed. JCVD is 44-4 in full contact kickboxing: http://en.wikipedia.org/wiki/Jean-Claude_Van_Damme
I saw an interview where he talked about how he was ashamed of using drugs, was a hero to his kids, and felt he needed to redeem himself. That's why he is doing this fight-- the first movie star to crossover and do a real fight.
JCVD is a lot bigger than Somluck, who competed at 57 kilos/130 lbs. We all know size is an advantage in a striking contest.
^Good info in this documentary.
