Watch on SFlix. Based on a narrative poem by Sir Walter Scott and set against the backdrop of feudal Scotland, "La Donna del Lago" is one of Gioacchini Rossini's finest operas -- yet it's rarely performed. This video gives viewers a rare opportunity to see the work in its entirety. Filmed at Italy's famed Teatro alla Scala in 1992 and staged by German film director Werner Herzog, the opera features vocalists Ricardo Muti and June Anderson in leading roles.
