When I have finished the script, I make copies for the 'actors'. Each scene is small and they can look at the words just before we start filming. We film at the weekend in my neighbourhood, **so** no one has to travel far. When the video clip is finished, I invite all the 'actors' and we enjoy the **film** at my house."
