It’s not for the weak at heart, this filmmaking career. And you have to learn to be resourceful. Don’t limit yourself to films. Go to the local television stations and see if they need creative help on their news and production sets. Work as an editor, or a shooter. Filmmaking is as much a craft as it is an art. Go to an ad agency. Screenwriters can write copy of all sorts while they wait it out for their scripts to be optioned. Odds are good that you are not going to start by making a blockbuster film. And even if you do, odds are slim there will be another one immediately to follow the first.
