'Wagner's Dream'
'Wagner's Dream'

Susan Froemke's "Wagner's Dream" follows the Metropolitan Opera's unprecedented four-year challenge: mounting a lavish new production of Richard Wagner's four-part "Ring Cycle." The classical music doc will have its premiere at the Tribeca Film Festival on April 25 (with a Q & A with filmmakers and opera stars Deborah Voigt and Jay Hunter Morris to follow) and opens in HD theaters worldwide on May 7 as part of a one-day event.

Wagner's four German operas "The Ring Cycle" (also known as "Der Ring des Nibelungen") have been intriguing and inspiring filmmakers for years. Terence Malick's "The New World" and Werner Herzog's "Nosferatu: Phantom der Nacht" both incorporate segments of the opera to hypnotic effect.
