These prominent filmmakers, "two of our most provocative and radical voices," discuss American historical events that have been forgotten—or hidden (Katrina vanden Heuvel, editor of The Nation). In working together on two challenging documentaries—South of the Border and the Untold History of the United States series for Showtime—filmmaker Oliver Stone engaged with author and filmmaker Tariq Ali in a probing, hard-hitting conversation on the politics of history. Their dialogue brings to light a number of forgotten—or deliberately buried—episodes of American history, from the US intervention against the Russian Revolution to the dynamic radicalism of the Wobblies; to how Henry Wallace's nomination for the vice presidency was deliberately thwarted by Democratic Party machine insiders; to the ongoing close connections between various US presidents and the Saudi royal family. For Stone, an Academy Award–winner, and Ali, an acclaimed novelist and journalist—two of our most insightful observers on history and popular culture—no topic is sacred, no orthodoxy goes unchallenged.
