SUMMER CAMP AND WINTER SOLDIER. If you're looking for an (extreme) alternative to the Film Forum's campy double feature of The Gang's All Here and Cobra Woman [see July 18, 2005], consider Lincoln Center's revival of the rarely screened 1972 documentary Winter Soldier, a record of testimony about atrocities perpetrated by U.S. troops in Vietnam. Michael Atkinson's Village Voice review makes a persuasive argument that Winter Soldier is still "imperative viewing." Tomorrow night's showing (with panel discussion) is sold out, but there will be screenings for about a week following.
