World War I in Color is a documentary (6 x 50-minute episodes) made with the cooperation of the Imperial War Museum, designed to make the Great War come alive for a 21st-century audience. The events of 1914-18 are authoritatively narrated by Kenneth Branagh, who presents the military and political overview, while interviews with historians add different perspectives. The human cost is conveyed by moving interviews with the now very elderly survivors, and by extracts from letters and memoirs.
Episode 7 in this authoritive series on WW1 in colour. Highly recommended
