So, you want to be a film maker. So you think you want to make a short film first. And you have an idea. What is it? Is it a premise (A guy walks into a bar. He's the best speed walker around, someone challenges him)? A smash of genres you think will go well together (Horror/Romance/Doco)? or Do you just want to do some cool VFX ("imagine if a guys ass exploded with giant flowers that turned into DVD's and the discs were eaten by a bunch of cables and satellites" (this could almost be a premise, sort of.))? Do you want to make people laugh, cry, both?
Whatever your idea, it's got to be short. You've got to get it in under 20 minutes right? Some people may say you can make it longer, and you can if you want to, it's your film. But short films are short films, so don't make it too long. We'll come back to time later.
Essentially the idea has to come from somewhere. For example, in my current short film that we've just cast, I wanted to work on dialogue and, directing dialogue well, so that it sounds natural. But just putting a bunch of people in a room and filming the dialogue can be very boring. So I needed to think of a purpose for the dialogue. Have a group of people, they can talk, then what.
Well, I like thrillers, and I like horror, and I like sci-fi. So that gives my dialogue a bit of direction. I have my idea for a short film, a dialogue driven horror/thriller/sci-fi. I called my idea: Woody Allen meets Wes Craven. Because, like it or not, as a learning film maker, even as a pro, you look at other peoples work for inspiration.
The spark of your idea is often the best part of the whole process, pure creation, it's all inside the head, your own little world of unlimited creation. Then comes the business of writing it down. Often an idea is hard to put into words, but the sooner you can do this the better off you'll be. Especially if you're not going to write the short yourself. You need to be able to express what you want to others. Writing it means you can say it out loud or send it in an email and still get the same message across. eg: "I've got this cool idea for a short film that would be cool, for you to write. Its like, um, this guy goes to this place and it won't take much money if you keep the locations easy and have only a few characters with this amazing idea".
"Ah, well, that sounds great! Send me an email"
As with the example above. Most people, film makers especially, will know what Woody Allen's films are like, even if they haven't seen them all, very dialogue and character driven. And even if you haven't seen many horror films, the chances are that you know Wes Craven for his Horror. It's simple really, it's your idea, but incredibly important, and most likely going to change as the film takes shape and more people get involved.
