Schtonk! (subtitled Der Film zum Buch vom Führer; "The film accompanying the Führer's book") is a 1992 German satirical film which retells the story of the 1983 Hitler Diaries hoax. It was written and directed by Helmut Dietl.

Plot

Fritz Knobel (a fictionalized version of real-life forger Konrad Kujau) supports himself by faking and selling Nazi memorabilia. He sells a portrait of Eva Braun and one volume of what he alleges to be Hitler's diaries (but which he actually wrote himself) to factory owner Karl Lenz. Lenz shows off the diary to his guests during a "birthday party for the Führer", among whom is sleazy journalist Hermann Willié. Willié works for the magazine "HH Press"; the letters HH are a licence plate abbreviation for Hamburg where the real-life Stern magazine is located, but are also the common abbreviation for "Heil Hitler" among neo-Nazis.
