Peter Del Vecho explains the decision of having two directors: "In story planning we're always together. That's myself, the head of story, the songwriters and Jen[nifer Lee] and Chris [Buck]; you can't do anything until you get that story working. But after that, we have the ability to keep Jen working on story while Chris is working on animation, and then they come together again in editorial. The idea of two directors is that they can come together to bounce ideas off each another when they need to but also split their duties a little bit so that, essentially, they can get more work done in a straight day."
