The number one thing is creating this world ["Trolls" ] - what the world is going to look like, feel like and what technology will we need to use to get there.

The Head of Story is defined differently for each film. But I found that the role for me was to support the director's vision, and to be a conduit to the story team - and managing that team to realize the vision.

I loved the Disney films, and Sterling Holloway was one of their chief talents. He never had to put on a voice, and that's what Mike [Mitchell] and I encourage. I love the voices that have a unique texture, but it's their real voice.

Since we've done that type of work [ voiceover], we know how isolating it can be, and we wanted to make the actors more comfortable.

We'd all [with Mike Mitchell] been together at Dreamworks for over ten years, so we all had the same goals.

I had to sit in front of all these people, and act like I knew what I was doing. I faked my way through it pretty well.

Sometimes actors come in, you record them, and they do their role.
