Through interviews with Herzog's close collaborators, including Robert Pattinson, Nicole Kidman, Christian Bale, but primarily through direct access to the protagonist himself and previously unseen archival footage, the film offers a captivating look into Herzog's creative process and personal life. François Truffaut once called Herzog "the most important film director alive." It's a documentary that must be seen because Herzog's story is primarily one about how to live a full life as a person and as an artist.
