Daniel Ellsberg

Daniel Ellsberg (First Run Features)

In the early 1970s, the name Daniel Ellsberg became synonymous with the Pentagon Papers, a hugely controversial document about U.S. involvement in the Vietnam War.

Its content clued much of the country in to questionable government dealings that set off a firestorm, and this Oscar-nominated documentary keeps Ellsberg - who provides present-day perspective on the events himself - at its center while also considering the effects of his actions. Others who were witnesses at the time are interviewed, as are historians. *** (Not rated: AS, P) (Also on Blu-ray)
