Start by capitalizing the page and number (i.e., PAGE ONE) at the top of the paper, followed by the number of panels on that page in parentheses beside the page and number. Each page of the script should start on a new piece of paper.
Indicate action in each panel by starting with "Panel" and number, followed by a colon (i.e., Panel 2:). Be as descriptive as possible regarding action and character descriptions. Try to keep action description to a sentence or two.
Show dialogue by typing character's name, followed by dialogue in all capitals. Indent dialogue. Place any modifiers in parentheses after the character's name. Use (thought) after the character if the dialogue is meant to show thoughts and not spoken dialogue so artist knows to use thought balloons.
Establish setting by typing the description in all capitals. Indicate sound effects and any captions to be used. Dialogue, captions and sound effects should be placed in the order they will appear when the art is drawn.
