…she loves Tove Jansson in general! 

This interview is from her webpage:

 

-I understand you’ve also recorded a track for the upcoming Moomin feature film? 

Yes. That was very joyous. They contacted me and asked me to write music for the film. After seeing a screening copy, I agreed to write the title track, and I asked Sjón to write the lyrics. The film looks great, and I feel it is much truer to the Moomin spirit than some of these Moomin things I’ve seen, which often stray from the original stories, have all these pastel colours and depict the Moomins as being all cute. This is a full length movie, about the comet, and it isn’t at all cute. It’s real, like the Moomins.

I felt that writing the track was a great opportunity to support [Moomin author] Tove Jansson. I’ve read many of her books—she wrote a lot beyond the Moomin series—and is now finally receiving due credit as a writer, not just of children’s novels. She has this great philosophy, and the way she lived her life on a small island is also inspiring. All her characters are different, everyone gets to be as they are and they all live in harmony. I agree with a lot of her messages, and really empathise with Tove.

 

Oh, Tove and Björk, loves of my life!

And by the way, here you can see the trailer for the new Moomin -film.
