Dubbed ‘La Stupenda’ thirty years ago by an Italian critic, Dame Joan Sutherland and her husband Richard Bonynge talk at length about her distinguished singing career and their life together in opera. The film combines documentary, archival material and performance to present a unique retrospective of those years. Affectionate contributions from some of their close friends and colleagues, including Luciano Pavarotti, Marilyn Horne, Dame Kiri Te Kanawa and fellow Australian Sir Sidney Nolan, add to a celebration of Dame Joan’s singular talent.
