I've worked with multiple directors throughout the 'Saw' series with a lot of conversations as they bring their particular installment to the screen. If I've been able to do anything throughout the course of these films, it's been to help shape dialogue and to try to make things as delicate and as intelligent as I can.
But I think there are a set of experiences that turn a potential writer into a working writer, and then there are places in your life were you start to recognize what you want to do.
