The stakes could not be higher as one of the theater`s finest stage directors teams up with one of the world`s leading opera companies to tackle opera`s most monumental challenge: a new production of Wagner`s Ring cycle-the four-part, 16-hour work that the composer first presented in 1876. Wagner`s Dream takes you deep into the artistic and musical challenges of the epic work. Visionary director Robert Lepage begins a five-year journey to create the most ambitious staging in Metropolitan Opera history, featuring a 90,000-pound set (``The Machine``) designed to realize all of Wagner`s scenic instructions. The film follows heroic singers from rehearsals to performance as they take on many of the most daunting roles in opera. An intimate look at the challenges of live theater and the risks that must be taken, the documentary chronicles the tremendous creativity and unflagging determination behind this daring attempt to realize Wagner`s dream of a perfect Ring.
