Just watched an interview with Jeffrey Donovan, star of the hit tv series "Burn Notice". He stated he was on the University of Massachusettes karate team and studied ju jitsu and aikido for ten years after college. He also says he works out the fight scenes with the fight choreographer on Burn Notice and does all the fight scenes himself, no stuntman doing it for him. I don't know what form of karate he took, I always thought he looked pretty good in those scenes were he was taking out the bad guys.
