In a post on ScreenCraft, Emily J says that storyboarding your screenplay (or novel) can help you think cinematically, build a visually engaging story, and strengthen your structure and pacing.
“If you find that you’re getting notes that your action lines too often focus on the ‘internal’ or your characters are stating exactly how they feel and there’s no nuance to it, try drawing out a few frames and describing what you’re seeing in the most simple and impactful terms,” she suggests.
