Hearts of the World

D.W. Griffith filmed some battle scenes during actual battles at the front in France. While he was out near the front trenches scouting locations, his party came under a surprise German artillery barrage. Griffith and his assistant jumped in a nearby ditch, and when the barrage was over they emerged from the ditch to discover that although they were uninjured, a shell had exploded near the ditch, killing the two soldiers acting as their escorts, along with a dozen other soldiers standing nearby.

A letter sent to The Boy from the Academie des Concourts is dated "7-30-1914." Europeans write dates with the day first and the month secondly. The letter from Paris should be dated "30-7-1914."

An expanded version, "Peace Edition", was released after the end of World War I.
