Writers pitch your screenplays. Producers browse for un-optioned spec screenplays.
"Unasked for attention" is when the grownups around him notice his artistic talents and accuse him of fraud. They don't see the faces he sees and can't understand how he can create such artwork. Aaron himself can't understand it either. We later learn, that the faces/creatures he sees are a reflection of his own inner feelings and after a brutal attack on his mother, these images become very dark and threatening. He needs to cope with what he sees and finally learns how to ignore most of them.
Let me know if you'd like a synopsis.
So ? I know, I spaced before the interrogation point. Sorry!
To answer your "So?" A producer is going to read what you wrote, and think you are a f******g idiot.
I AM A F*******G IDIOT. THAT'S WHY WE WRITE SCREEN PLAYS TO PUT IN OUR DESK DRAWER FOR NOBODY TO EVER PRODUCE. LOOK AT ALL THE LOG LINES WITN "0" INTEREST. WE ARE WASTING OUT PRECIOUS TIME, I COULD BE PLAYING GOLF. OR WE COULD PAY THEM TO TELL US HOW TO WRITE....TAKE AWAY OUR CREATIVITY. GOOD LUCK.
