“Selma” (May release) depicts the civil rights march from Selma to the state capital of Montgomery Ala., which dramatized the case for voting rights for Afro-American citizens. Other than the portrayal of President Lyndon Johnson as lukewarm to the cause, the film as thought to be generally accurate and draws it’s drama from reconstructing the events leading up to the March. (The recent book “an Idea whose Time Has Come” details the political manuevers that got the Voting Rights act through Congress). Another political film with an Oscar pedigree but of an older vintage, is “Z”, a thinly fictionalized account of the assassination of a democratic Greek politician, Grigoris Lambrakis, in 1963. More passionate than strictly historical, the film captures the outrage at the time over the military dictatorship that was taking charge in Greece. The Documentary-like style makes for fast-paced and dramatic viewing.
