　　核试验科教记录片。是自人类发明原子弹、氢弹以来的各种核爆炸记录，采访了许多美国参与核试验的专家，非常珍贵的第一手资料。着名的“小男孩”（广岛）和“胖男人”（长崎）就在这里，不可不看！ 　　On July 16, 1945, at a site called Trinity, a plutonium bomb was assembled and brought to the top of a tower. The bomb was detonated, producing an intense flash and a fireball that expanded to 600 meters in two seconds. The explosive power was equivalent to 18.6 kilotons of TNT. It grew to a height of more than 12 kilometers, boiling up in the shape of a mushroom. Forty seconds later, the blast of air from the bomb reached the observation bunkers, along with a long and deafening roar of sound. And so began the ATOMIC AGE... 　　"Trinity and Beyond" is an unsettling yet visually fascinating documentary presenting the history of nuclear weapons development and testing between 1945 until 1963. Narrated by William Shatner and featuring an original score performed by the Moscow Symphony Orchestra, this award-winning documentary reveals previously unreleased and classified government footage depicting in graphic detail these powerful and awesome weapons. Many scenes were restored with an Academy Award? winning process created to restore the color. 　　Director/producer Peter Kuran, traveled throughout the U.S. to locate footage that includes bombs being suspended by balloon, exploding under the ocean, being shot from a cannon and detonated in outer space.
