The key players in the radical movement known as the Weather Underground are skillfully brought to life in this Oscar-nominated documentary. The Weathermen were born of sixties protest, but took their scheme to overthrow the U.S. government to especially violent extremes. Never a well-populated movement, the Underground petered out as its leaders aged during the seventies; by decade's end, weary of hiding, most of them had turned themselves over to the authorities. That journey, by which a fire-breathing revolutionary such as Bernadine Dohrn became a (still fiery) gray-haired wife and mother, is an intriguing one. This film, rich in period footage (and some unnecessary sensationalism) captures the era somewhat broadly. But the present-day interviews with the participants, contrasted with their radical selves, provides an exceptionally detailed look inside the organization itself. It's not a nostalgic look back, and the overall mood is sobering rather than celebratory. Lili Taylor provides the narration. --Robert Horton
