Is it possible that the one thing that producers value the most in writers is the ability to finish a screenplay?
Read this good news from a guy named Joel.
It's probably refreshing for a producer to see that a writer can string enough words together to fashion a full-length script; a script that hits all the important beats of the Syd Field model/hero's journey/etc.; a story with a beginning, middle, and end. More important than sheer talent or ability to spin b.s. is the ability to push through to a "done."
(Found out about Joel through Alex Epstein. If you have an interest in writing, he has a couple of swell books on the subject.)
