Here's an interesting bit:

"I'd like to write and perform some more movie soundtracks without doubt, because there's a whole science to it. I put it off for a long time because I had offers over the years, and it never seemed like the right time, and the films just weren't right. But The Big Bang felt right because the director [Tony Krantz] had been working with the sound of the first Healers album in mind. And I was obviously going to do Inception because I love Hans' stuff and I love [Christopher Nolan's] Memento. And coincidentally David Cross did Todd Margaret, and he and I had played together once before, in New York before a Modest Mouse gig. We did a satirical send-up of this corporate American conference where this Bank Of America conference guy did a version of U2's One."
