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.

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.

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.

If you hug someone for seven seconds, it gives you a chemical drop in your brain.

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 world is in such a place of social unrest and there's so much violence.

Mike [Mitchell] brought me on as co-director, and eventually we ended up sharing a brain. It was overwhelming initially when I was working with departments I hadn't had contact with before.
