Man Bytes Hollywood:
"Last week I finished revising the scriptment for my Animal Story. I’ve received very positive feedback so far. Writing a scriptment was part of an experiment for me, and a revelation. I’ve been very deliberate in planning this screenplay and it marks a turning point in my writing. A quantum leap in quality — and I was good before.
Thus, I have taken this vow: no more vomit drafts.
If you come to a similar place in your writing as I have, you might consider this approach as well."
