Oh Sport, You Are Peace! | 1980 Moscow Olympics documentary

Yuri Ozerov's record of the 1980 Moscow Games runs from the mass choreography of the opening ceremony through the finals and records to the closing night send-off of Misha the bear. It is the official film of an Olympics that dozens of countries boycotted, staged at full Soviet scale anyway.
