Historian Michael King's opus was a bridge between Māori and Pākehā; he turned Aotearoa's history into an unprecedented publishing bestseller. History Man traces King's own past, to understand the man and his passion for his work. This doco was commissioned only weeks before King and his wife were tragically killed in a car accident. Nevertheless it is a detailed portrait of a much loved and missed New Zealander. It is another collaboration from this producer/director team, whose subjects include Michael Houstoun, Ian Mune and Barry Crump.
