To Kill a Mockingbird' represents Hollywood at its very finest, when a popular film could truly contain a message. It has one of the most moving scores of all time.

I've worked with a lot of directors, some of them you wouldn't really attach the word 'artist' to their name.

Choose your mutations carefully...

When I was a kid, the book that I liked the most was 'Aesop's Fables.' There was a version of it that my father read stories to us kids out of. I liked the idea of the short story format.

Lego was our fourth film, because we did two Cloudys, so yeah there's a little bit of shorthand that's involved and then you can anticipate things- because for me it's like, I get a script for a movie and I go, "Wow that's a pretty good script", then you sign on and a couple months later they show you the first cut and you're like, "Whoa, how did that happen?"

When I was a kid, I would go to the record store, where there was a bin of things they didn't know quite how to classify. Those were my choices. That's where you would find Captain Beefheart or an early electronic album.

This is the fourth movie that I've done with this set of director-writers and I've learned to trust them at this point, because actually I started on Lego before they did.
