Directed by Academy Award-winner Peter Jackson, They Shall Not Grow Old explores the lives of soldiers during World War I, using never-before-seen archival footage that was restored and updated with modern technology.

We all learned about World War I at school, but very few of us have heard from those who actually fought.

Dedicated to his soldier grandfather, Peter Jackson's They Shall Not Grow Old seeks to provide an authentic look at World War I.

Jackson was commissioned to make this 2018 film by the Imperial War Museum, which gave him access to an extensive archive of footage.

This colorized film is complemented by detailed accounts from dozens of WWI soldiers, all of whom remain anonymous throughout the film.

Drawing on oral accounts, Jackson gathers a range of diverse perspectives into one unified story of World War I.

The documentary follows the war from the premature euphoria that met its onset, to the hardships and horrors of trench life. It's a vivid new account of the Great War as told by those who fought in it.
