When I'm writing a theme song for a TV show I always think, "What would be Pavlovian where a kid would be in the kitchen, or an adult would be in the kitchen, and they hear the theme song come on and it would draw them back to the other room so that they would watch the show?"

It's people who write music because they are obsessed that I like; because they have something to say and no other way to say it.

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.

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.

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?"

The stories I write are often literal to events that have happened or observations that I've made, and sometimes they're fantastical.
