The document discusses storyboards and their purpose in film pre-production. It explains that storyboards are drawings of each planned shot accompanied by descriptions of the action and dialogue. This allows directors to make important decisions in advance, like composition, camera angles, and blocking, and essentially pre-edit the film. While storyboards don't have to be strictly followed, they provide an overall view of the story and inform the crew. However, some directors feel storyboards eliminate spontaneity that can lead to new ideas.
