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've always loved that film ['The Three Caballeros'], and we were looking for a way to apply it to our own work, and 'Trolls' was it - psychedelic, musical and kinetic insanity.

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.

It was so complex [in "Trolls"] that the technical team had to build a new program. It was about rendering and manipulating that weird hair. We also wanted to break the mold of what what we thought the princess was about...we wanted to keep her troll 'look' - the stumpy legs, an ugly/cute look, it was all inspired from the doll.

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

We actually talked about Adam Sandler during the creation of 'Trolls,' because he does know how to time jokes.
