I got A* in my coursework but mine has also been sent off for moderation so who knows what'll happen. Basically, you need a storyline, a few characters and a few locations. Maybe a tag line too. Most of that is easier once you have a stroyline. Then design a storyboard for the trailer or the beginning of the film. Design a poster and design a web page as any of these could be an option for question 4. For question 3 think about how your film hits the target audience and how you could market and merchandise you're film, eg. dolls, tops etc
