I had the pleasure of screening a 2006 documentary on Børge Ring made, I believe, for Danish TV. It's a half hour long and includes photos and footage of Børge talking about his films, as well as shots of his home, his wife Joanika and her sculptures, and a guest appearance by animator Kaj Pindal. The film also covers some of Børge's career as a professional jazz musician.
(Right now on Ebay, you can buy an LP of De Millers at the North Sea Jazz Festival, recorded in the early '80's and featuring Børge.)
I don't know where this documentary is scheduled to be screened. Keep an eye out for it at festivals. Somebody should package this film and Børge's animated films together and release them on DVD. The documentary shows that Børge is working on a new animated short and I'm looking forward to seeing it.
If you're not familiar with Borge's films, you can watch Oh My Darling and Run of the Mill on YouTube. Unfortunately, Anna and Bella is no longer posted there.
