"Lüge und Wahrheit" ("Lie and Truth") is a German documentary that investigates the mechanics of disinformation and the social cost of a blurred line between fact and fiction. The film examines how false narratives spread through digital platforms, political messaging, and traditional media, and why audiences often find manipulated content more compelling than verified reporting. Interviews with journalists, psychologists, and platform researchers frame a portrait of a public sphere under pressure from propaganda, conspiracy theories, and information warfare. Part of the Kantara Films & Documentaries archive, the documentary fits the company's wider focus on politics, society, and media accountability. It is aimed at viewers looking for a considered account of how truth is contested in the 2020s and what tools exist to defend it.
