Watch Full Movie Online. Bass René Pape, the world’s reigning Boris, reprises his overwhelming portrayal of the tortured tsar caught between grasping ambition and crippling paranoia. Conductor Sebastian Weigle leads Mussorgsky’s masterwork, a pillar of the Russian repertoire, in its original 1869 version, which runs two-and-a-quarter hours with no intermission. Stephen Wadsworth’s affecting production poignantly captures the hope and suffering of the Russian people as well as the tsar himself.
