Director Brett Morgen on 'Moonage Daydream' and how David Bowie saved his life

It's almost as if David Bowie has come back to life to narrate the movie "Moonage Daydream", a vivid collage of the music, art and ideas that make up his extraordinary legacy. US filmmaker Brett Morgen spent years sifting through endless audio and film archives and the result is an innovative, sensorial portrait of a man with many faces. The director tells FRANCE 24's Eve Jackson how making the documentary saved his life and discusses his impressions of David Bowie when he met him in person.
