n. A script editor
Wikipedia
Story editor is a job title in motion picture and television production, also sometimes called "supervising producer". A story editor is a member of the screenwriting staff who edits stories for screenplays.
The story editor has many responsibilities, including finding new script/breakdown writers, developing stories with writers, and ensuring that scripts are suitable for production. The story editor will work closely with the writer on each draft of their story and script, giving the writer feedback on the quality of their work, suggesting improvements that can be made while also ensuring that practical issues, like continuity and correct running time, are adhered to. When a script is past due, multiple people may write an act—called "gang banging" a script. Many primetime series have an executive story editor and a story editor.
Marc Abrams of the TV series The Bernie Mac Show said, "As you go from show to show you learn that each has its own temperature and its own etiquette. You recognize your role on that particular show. Certain show runners encourage the lower-level writers to pitch ideas, others don't. Some want ideas well thought out before they are presented, others like to hear the kernel of an idea that could be expanded."
This role often overlaps with that of the head writer.
