"Narrated by Oliver Stone, this new one-hour series features human events that at the time went under reported, but crucially shaped America's unique and complex history. The first chapter explores the birth of the American Empire by focusing on Franklin D. Roosevelt, Winston Churchill and Joseph Stalin. Through examination of key decisions during World War II, discover unsung heroes such as American Henry Wallace and explore the demonization of the Soviets." (source: www.sho.com)
I found this online as a torrent, and uploaded it without explicit permission. The second episode is nowhere to be found. You can, in theory, view it on Showtime On Demand, though that doesn't seem to work outside the USA.
