Hi, i am Liam Neeson. I first met Andy Norman by year 2004 when we were preparing to shoot Batman Begins. We brought Andy Norman as a fight consultant , not only he's a great superb guy but he also evolved this incredible defence system called DNA , Defence in Action. If you really want the self protection defence system , this is the way to go.
It's really practical. it's all about using what's available grabbin ashtry smacking somebody with it or be able to fight with somebody while sitting next to them. And it is really great fighting style.
