Herzog, Green Screen, Lang

Studio 360 escapes into the jungle. Werner Herzog talks with Kurt Andersen about his new movie, Rescue Dawn, which tells the true story of the mind-boggling heroics and survival skills of Vietnam War pilot Dieter Dengler. Movie actors tell us what it’s like working with a green screen —- where their computer generated costars get filled in later. And singer k.d. lang looks back on her Canadian roots.
