The Fugitive (1910)
The Fugitive is a 1910 American drama film directed by D. W. Griffith. Prints of the film survive at the film archive of the Library of Congress and at George Eastman House. The script was by John MacDonagh, who would later fight in the 1916 Rising under the command of his brother, Thomas MacDonagh, one of the seven signatories of the 1916 Proclamation, who would be executed by the British along with 15 other leaders after the Rising. John MacDonagh's script was originally on an Orange/Green theme, and set in Ireland where unionists and nationalists were at war, rather than the American Civil War theme to which it was adapted. The plot involves two soldiers, one Confederate and one Union, who leave their families to go to war. After a skirmish they end up separated from their own sides; the Union soldier shoots the Confederate. Escaping from pursuing Confederates, he looks for refuge in the house of his enemy's family.
