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

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.

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.

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.

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

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.

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.
