Egad! What's a scriptment?

Sabina, it's a hybrid treatment with script elements, sometimes used by writers to flesh out their story. James Cameron, for one, is fond of them and if you bump around the web, you can find ones he did for Spider-Man, Strange Days, and others. While there are no guidelines to format, I do go into this narrative approach to some depth in my Story Summaries: From Loglines to Beat Sheets.
