Trailer for Countdown to Zero.
Traces the history of the atomic bomb from its origins to the present state of global affairs: nine nations possessing nuclear weapons capabilities with others racing to join them, with the world held in a delicate balance that could be shattered by an act of terrorism, failed diplomacy, or a simple accident. Written and directed by acclaimed documentarian Lucy Walker, the film features an array of important international statesmen, including President Jimmy Carter, Mikhail Gorbachev, Pervez Musharraf and Tony Blair. It makes a compelling case for worldwide nuclear disarmament, an issue more topical than ever with the Obama administration working to revive this goal today.
