In the documentary "David Wants to Fly", German filmmaker David Sieveking feels a bit lost after graduating from film school, and upon seeing an ad for a conference, he travels to the U.S. to hear a talk about the source of creativity by filmmaker David Lynch.
This is the start of an interesting journey of examining the Transcendental Meditation technique.
Karin Badt from Huffington Post has written a very good and balanced review of the film.
