"Les Dossiers de l'écran" (The screen's files) was a most revered TV show on French tv in the 70's- 80's, with notable guests from many backgrounds, each show was focusing on a subject, and it was quite the intellectual rendez-vous of the week on that channel, between others.

This one is featuring the King of Cambodia Norodom Sihanouk, and many other intervenants, including UK journalist William Shawcross and AUS journalist Wilfred Burchett for this very special discussion about what just happened then, aired on 27 November 1979.
It's in French, with acceptable subs in English, although not yet ideal.
