whenever i write a new spec, i do a lot of research on the show. i watch every episode in order and take notes while doing so. then i get my hands on actual scripts from the show, and proceed to break them down to figure out the show’s structure.
i list all of the sluglines, what happens in each scene, how long the scenes are, and which characters are in each scene. then i color code the scenes so i know which are the A story, B story, runner, etc.
this is a screenshot of the crazy excel file i created before i wrote my 30 rock spec that got me into the nick fellowship.
