By World War II locally-made movies were largely missing in action: Broken Barrier marked the first NZ dramatic feature since 1940. Its production saw makers John O'Shea and Roger Mirams crowd into a Vauxhall with a rickety dolly and two silent cameras, one picked up "from a dead German in the Western Desert". Ditching dialogue for 'spoken thoughts', the pioneering film examines cultural complications in a romance between a Pākehā journalist and a Māori nurse. According to O'Shea, some viewers considered it "a dirty movie" for spurring mixed race relationships.
