Wonder if the Kiwi's know...
That when they showed this in Australia (I think a few days after NZ)the hoax was revealed immediately after the film by some network personality (can't remember who) who said the purpose of the film was to prove how stupid New Zealanders were. "After the film aired in New Zealand," he gloated "80% of them believed it was true."
As a very young ex-pat Kiwi living in Australia I remember thinking at the time that it was hardly fair to compare which country was most gullible as they hadn't taken any time to see what percentage of Australians fell for the hoax.
I did fall for it - despite the impossibility that such achievements had somehow gone unnoticed all those years. At that age I proudly identified myself as a New Zealander and I wanted so badly for it to be true (Kiwi's flying before the Wright bros!) I think that's the real point of the film - it plays on our need to have our patriotism validated by discovering that we really ARE the greatest country on earth after all...
