The Greatest Thing in Life

The Greatest Thing in Life is a 1918 American silent drama film about World War I, directed by D. W. Griffith and starring Lillian Gish, Robert Harron, and David Butler. The film is now considered lost, as no prints are known to exist.

After attaining significant fame as a director of war pictures, D. W. Griffith was invited by the British government to film on actual World War I battlefields. Griffith had originally intended to make only a single picture with the material, but came back with over 86,000 feet and decided to turn it into three.The chief production was Hearts of the World, with The Great Love and The Greatest Thing in Life made with the leftover battlefield footage. Some of the footage was filmed on the Marne River in ChteauThierry, France. There is some speculation, however, as to whether some of the shots originated in Salisbury Plain, in the United Kingdom, or was footage purchased by Griffith from Franz Kleinschmidt. ........
