"Lincoln" director Steven Spielberg speaks in Gettysburg Steven Spielberg asked sixteen newly minted Americans to remember equality as the Abraham Lincoln biopic director marked the 149th anniversary of the president's famous "Gettysburg Address." Spielberg addressed citizens from 11 countries who took the oath of allegiance to become U.S. citizens Monday at the Soldier's National Cemetery in Gettysburg. After spending seven years working his new movie "Lincoln," Spielberg says the 16th president came to feel like one of his oldest and dearest friends. He says Lincoln would want us to realize equality is a "democratic essential." Lincoln gave the three-minute speech, which famously begins with the phrase, "four score and seven years ago," at the dedication of the cemetery four months after the battle. Previous speakers include presidents Harry Truman and Dwight Eisenhower, and former Pennsylvania Gov. Tom Ridge. Iconic Abraham Lincoln portraits Carl Sandberg, in his biography of Lincoln, said it was a speech that conveyed the message that democracy was worth fighting for. "It had the dream touch of vast and furious events epitomized for any foreteller to read what was to come," Sandberg wrote. His cadences sang the ancient song that where there is freedom men have fought and sacrificed for it, and that freedom is worth men's dying for. Gettysburg is where the U.S. military was able to stop an invasion of the North by Confederate troops under Gen. Robert E. Lee, a major turning point of the American Civil War. The 150th year since that battle will be marked in 2013, particularly around the battle's anniversary in early July. "Lincoln," which stars Daniel Day-Lewis in the title role, concentrates on the period leading up to the president's assassination in 1865. The film also stars Joseph Gordon-Levitt, Sally Field and James Spader. The Civil War drama expanded nationwide after a week in limited release and came in at No. 3 this past weekend with $21 million.
