Plot synopsis: Robert Altman's life and career contained multitudes. This father of American independent cinema left an indelible mark, not merely on the evolution of his art form, but also on the western zeitgeist. With its use of rare interviews, representative film clips, archival images, and musings from his family and most recognizable collaborators, Altman is a dynamic and heartfelt mediation on an artist whose expression, passion and appetite knew few bounds.
