First-time director Adam Benzine was a professional journalist before he started to do a documentary film, just like his subject Claude Lanzmann.
The interview with Claude Lanzmann was shot in 1 week in Paris, France. Lanzmann was 87 years old at that time. He did the interview for free.
First-time director Adam Benzine financed the shoot himself. He finally could get investments from European TV stations when the short documentary was nearly finished.
According to director Adam Benzine the production took 4 years from the first idea to the finished film.
The archive footage shown is mostly from the outtakes of Shoah (1985). They are part of the 'Claude Lanzmann Shoah Collection' in the 'Steven Spielberg Film and Video Archive' of the United States Holocaust Memorial Museum. They are in the public domain now.
