When Academy Award-winning actor Sean Penn set off to make a documentary about Ukraine, he thought he would be telling the story of a comedic showman-turned president named Volodymyr Zelenskyy and the young democracy that had elected him. Instead, Penn found himself witnessing the start of a horrific war of aggression. Sean Penn joined Michael McFaul at Stanford University for a special screening of "Superpower," a film co-directed by Penn and Aaron Kaufman about the days leading up to and immediately following Russia's full-scale invasion of Ukraine in February 2022. During their discussion, Penn shares what it was like to be an accidental witness to history, and the inspiration he continues to take from President Zelenskyy, Ukrainians, and their fight for freedom. Natalia Antelava, editor-in-chief of Coda Story and a John S. Knight Journalism fellow at Stanford, moderates the conversation.
