Although Marcel Ophuls, who has died aged 97, became a film director like his prodigious father, Max, he managed to avoid comparisons by taking the route of documentaries rather than fiction.
Certainly, The Sorrow and the Pity (1969), his documentary on the behaviour of the citizens of the French city of Clermont-Ferrand during the second world war, and the Oscar-winning Hotel Terminus: The Life and Times of Klaus Barbie (1988), a detailed biography of the notorious Gestapo chief, put Ophuls on a level that made any reference to his father an irrelevance.
