What is the first step to becoming a filmmaker?

I am an editor and maybe have a little advice for you. DON'T DO IT!!! No, just kidding. It is a great deal of hard work though--and very little glamor. You don't have to go to school, although school is fun and a good learning and growing experience in general. But the best school is doing it. In other words, instead of spending thousands of dollars a year for four years, just volunteer at a film company, and help them.

You must do and be a few things:

Reliable--always show up on time, do what you say you will do, be efficient and good natured, and communicate with your boss openly. Call them if you will be late, and always be ready emotionally to work.

Work hard--This is what will get you respect (and possibly, future work). Believe it or not, it is difficult to find good workers in Los Angeles. There are plenty of workers, but not plenty of reliable, hard working, high-energy workers.

If you want to become an editor--starting as a PA can be good--but don't lose sight of your goals as an editor. Tell people as you apply for the PA job that your future goals are to be an editor. Tell everyone. After getting to know people on the set, tell them you want to help out in the editing room.

Of course, your goals may change, but as long as you're clear, let people know.

Realize also that you may hit a few bad apples in the film world who will want to use you and abuse you--make them treat you with respect but also realize the only work you can do for them that could be useful is the simple (and sometimes boring and tedius) work. BUT this gives them no excuse to treat you badly. You are an important person too.

Anyway, there are no "normal" routes to getting into Hollywood. You will have to be the best person you can, work hard, be enthusiastic, don't let the bad apples get you down, and keep plugging away. One day, if you want it bad enough, you will get your dreams. The question is, "What are your dreams?"
