Anzac Day Collection – Collection | NZ On Screen
From their overview:
This collection brings together 24 titles covering Kiwis at war. Iconic documentaries and films tell stories of terrible cost, heroism and brotherhood. Each title raises fundamental questions about our identity. Dr Chris Pugsley muses, “It is sobering to think that in the first half of the 20th Century the big OE for most New Zealanders was going to war.”
