Awh, this kid reminds me of me when I was 13. I remember writing a full 90+ page screenplay and thinking I was gonna make it big in Hollywood off the back of it. Oh, those were the days.
Then I grew up and realised if you want to make it as a Hollywood screenwriter (assuming you don't live in Los Angeles or New York City and have a shit load of good connections) the only way to get into writing movies is via writing novels. Now I couldn't think of anything worse than letting a bunch of bloodsuckers like the Hollywood film industry anywhere near anything anyone of any credibility had ever written.
Anyway, let the kid have his little dream. Its nice to have a goal, even if it is unattainable. When he grows up and realises how the world works he'll wise up. Not that I give a shit about any of this, it just makes me feel all nostalgic.
