Although she remains in the shadow of Claude Lanzmann, Ziva Postec was an indispensable part of the project. She dedicated six years of her life (1979 - 1985), to constructing the right pace and sequence for 350 hours of footage documenting the "extermination process." Postec recalls the gargantuan nad painful task for Catherine Hébert's camera, revealing the film's profound impact on her personal life. Ziva Postec is a moving portrait of unnoticed artist, eclipsed by her male colleague.
