Okay, so there are three main questions you need to think about as to go on about planning a movie. You need to think about what you're going to shoot! you need to think about why you're doing it and you should think about how you're going to go out and get all the shots you need to tell your story. So the question why is the best place to start because it's the most fundamental question. What is it that you're trying to do? Think about the effect you want to have in the world what sort of people are going to watch this and what are they going to think and feel while they do that and what are they going to go out and do as a result. Once you have an idea why you're shooting something it's time to start thinking about what if you're stuck at this point take a look around at other people's work and take note of the things that you like. In all this list are your friends they'll help you to organises parts of your stories so, write things down or government top to someone about it and then come back to it and then come back to it again. Once you know what you have it's time to think about how you're going to go about getting that so, it's time to think about what sort of people you want to involve the sort of places you want to go and the equipment you're going to need to capture the footage you want.
