This year marked the 100th anniversary of the Armistice of November 11, 1918, which brought an end to The Great War (World War I), and a new documentary from Peter Jackson will be bringing the events of that conflict to life like never before. Warner Bros. have released a new trailer for THEY SHALL NOT GROW OLD, which shows off the incredible restoration work which has gone into making the 100-year-old film footage like damn near brand-new.
