Ron McIntyre

As a war correspondent filming New Zealand's forces in Italy and the Middle East, Ron McIntyre played a key role in supplying raw material for the early films of the National Film Unit. After nearly four years overseas, he returned home and tried his hand at independent filmmaking. McIntyre spent just over seven years with the NFU as a cameraman and director, and also worked briefly for Pacific Films.

I suppose if there's any value at all in war film, it might be to finally convince people of the utter stupidity of the whole thing. Ron McIntyre, in an interview for episode five of 1973 TV series The Years Back
