Editing rooms are kind of, by definition, a bubble of you and the editor and what you're thinking. It's a truth-telling thing to watch it through someone else's eyes, is to get another level of real with your material. Like, "Maybe that's not that funny. Maybe that's not as interesting. Maybe that's redundant to something else. Maybe we can cut down." I don't know. It's a brutal, honest process. You've got to be pretty - You can't be sentimental. You have to be. It's a cold process. You can't be nostalgic. You have to make those tough decisions.
