I attended a Wing Chun class on Tuesday and must say the technical aspect fascinated me in a big way. Its totally different to karate.
I think I will give it a try primarily for the close-combat techniques which I feel could work nicely for the camera.
There is also a Aikido school close by but I think its a style best suited to somebody who would more than likely play a hero in a movie. Brushing up on some gymnastics/parkour is a good idea because falling nicely(hard yet controlled) is what makes the good guy look better too.
For now Wing Chun will be my choice as I feel it will challenge my mental focus and reflexes most.
