We may now have our film genre but we still have to decide on what the story is going to be about. It is said there are 22 different types of story you could have. No matter what wonderfully innovative idea you come up with it will fall under one of these 22 stories. So if its about a cat that finds himself trapped in a dungeon and has to be rescued by a seagull but there's no way in, even though its strange it will still come under one of these story types.
Next up is some more research on the film title openings to see what the conventions are of different film genre titles.
