I’d sit and talk to them about my thoughts on what I wanted to achieve within each of the action scenes and then they’d start putting and devising some of the sequences for me to see. I’d then comment and work with them to adapt it. As a director, I’m quite hands on and we worked very closely. Obviously they are hugely experienced at what they do and I also wanted to give them the freedom to be able to undertake that. The finale in the film in particular was very special.

Anthony Carpio and Chan Man-Ching real helped make the action possible in the film. They really pay attention to details and as I said earlier it was great to see them at work. They have such a vast wealth of experience and knowledge and are both really good guys. They always strive to push things and make things better. Collectively, I am very proud of what we achieved in HK.
