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.

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.

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

I was trying to foster a great working relationship between those two departments [design and the writing teams], because classically in animation the two don't get along.

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.

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

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.
