You must have identified a clear target audience and you must show the steps you've taken to identify it and to test your ideas against this specified audience. This doesn't mean just an endless series of questionnaires. Use the range of techniques discussed including interviews, preferably with your target audience, and the tools available through Web 2.0.
Look at similar films and research their audiences - How was it marketed to appeal to the target audience? What are the viewing figures?
You must be able to answer these questions fully and with illustrations:
1. What is the core target audience? Is there a secondary target audience?
2. How would you describe the look and tastes of your target audience? (collage with key words perhaps)
