H: What was the writing experience on Black Books like? Was it a collaborative process, or did you bring in scripts/tinker with those of other people?
KC: For Black Books we would work on a storyline and discuss it with Dylan and then we’d write two drafts and get feedback from the producer. Then Dylan would do a draft and after that, if it needed it, it would go back and forth between us and Dylan. Then in rehearsal it would change a bit more. We didn’t work on other writers’ scripts on that show, just the ones where we are credited, so eight in total. There wasn’t a writer’s room in the American sense. It was very collaborative because it was Dylan’s show so it had to sound right to him or it wouldn’t have worked.
