impact

What interests me about making a film is the impact the original idea makes on me in the first place. That's what I hang on to. That's what I try to remember all through the shooting and cutting and editing. Because films are all in bits and pieces and you can easily lose track of the main objective and that's where you go wrong. I don't really explain to myself why it has such an impact. It's like a girl you're in love with. I try to remember the emotional impact it made on me initially. After that it's what the actors do to it.
