The process of writing for '43 pounds' is significantly different from the work I usually do. There are two reasons for this:
1) We are going to be relying heavily on the excellent improvisational skills of our cast. This should give us more of a documentary feel - less like scripted lines. So the lines I am actually writing will probably never be spoken. They are there to guide the actors rather than constrain them.
2) I already know some of the cast and have started workshopping with them. This has given me the seeds of several ideas. And when I type the words in, I can already hear the voices of the actors saying them.
Hearing voices may sound more like a mental illness than a writing technique. Perhaps it is more accurate to say that when I read the lines that I have written, I hear them in my head with the tone, accent and delivery of those individuals.
Getting the voices is one of the important milestones for me in writing any work of fiction. With this it has been given to me from the start.
