Question: The German propaganda film, Triumph of the Will, included excerpts of speeches by Rudolf Hess, who was Deputy Fuhrer from 1933 until when?
Context: Triumph of the Will (German: Triumph des Willens ) is a 1935 German propaganda film directed, produced, edited, and co-written by Leni Riefenstahl.  It chronicles the 1934 Nazi Party Congress in Nuremberg, which was attended by more than 700,000 Nazi supporters.  The film contains excerpts from speeches given by Nazi leaders at the Congress, including Adolf Hitler, Rudolf Hess and Julius Streicher, interspersed with footage of massed Sturmabteilung (SA) and Schutzstaffel (SS) troops and public reaction.  Hitler commissioned the film and served as an unofficial executive producer; his name appears in the opening titles.  The film's overriding theme is the return of Germany as a great power, with Hitler as the leader who will bring glory to the nation.  Because the film was made after the 1934 Night of the Long Knives (on 30 June) many prominent Sturmabteilung (SA) members are absent—they were murdered in that Party purge, organised and orchestrated by Hitler to replace the SA with the Schutzstaffel (SS) as his main paramilitary force. The Fox of Glenarvon (German: Der Fuchs von Glenarvon) is a German propaganda film from the Nazi era portraying the years of the Irish fight for independence during World War I.  It was produced in 1940 by Max W. Kimmich and starred Olga Tschechowa, Karl Ludwig Diehl, Ferdinand Marian and others.  The screenplay was written by Wolf Neumeister and Hans Bertram after a novel of the same title by Nicola Rhon (Maria von Kirchbach) that had been published at Ullstein publishing house in 1937.  The shoot lasted from December 1939 to February 1940.  It passed censorship on 22 April 1940 and had its debut in Berlin's Ufa-Palast am Zoo two days later. Karlheinz Pintsch (1909 -?)  was the long serving senior adjutant to Rudolf Hess who was the Deputy Führer to Adolf Hitler in Nazi Germany.  It fell to him to report Hess's illegal May 1941 flight to Scotland to Hitler and his recollections and notes have been the subject of debate by historians. Blut und Boden - Grundlagen zum neuen Reich (English: "Blood and soil - the foundation of the new reich") is a 1933 German propaganda film that illustrates the Nazi concept of "Blood and Soil".  The film has both dramatic and purely documentary aspects, following a German farming family as they have their farm foreclosed on, are forced to move to the city and eventually return to farming in the German East.  The documentary uses both animation and montage to present the case that the German farmer is suffering because Jewish financial interests flood the market with foreign produce, refuse to lend money for the manufacture of farming equipment and foreclose on people's farms. Wolf Rüdiger Hess ("Heß" in German; 18 November 1937 – 24 October 2001) was the son of Rudolf Hess and Ilse Pröhl Hess.  He was also an outspoken critic of the investigation into his father's death, which he believed was a cover-up.  He maintained that the British Secret Intelligence Service (SIS) had murdered his father in order to prevent his parole—which he believed to be imminent—because the British government were afraid that his father, if allowed to speak freely, would reveal embarrassing information about British actions during World War II.  In 2007, however, documents demonstrating British support for Hess' release on humanitarian grounds and their campaign against steadfast Soviet opposition to his release were published. A Film Unfinished (Hebrew title: "שתיקת הארכיון" "Shtikat haArkhion", German title: "Geheimsache Ghettofilm") is a 2010 documentary film by Yael Hersonski, which re-examines the making of an unfinished 1942 German propaganda film (titled "Das Ghetto", "The Ghetto") depicting the Warsaw Ghetto two months before the mass extermination of its inhabitants in the German operation known as the Grossaktion Warsaw.  The documentary features interviews with surviving ghetto residents and a re-enactment of testimony from Willy Wist, one of the camera operators who filmed scenes for "Das Ghetto".  It premiered at the 2010 Sundance Film Festival, where it won the "World Cinema Documentary Editing Award".  At the Hot Docs festival in Toronto, the film won the Best International Feature award.  The film was released theatrically in the US on 18 August 2010. The Party Chancellery ("Parteikanzlei"), was the name of the head office for the German Nazi Party (NSDAP), designated as such on 12 May 1941.  The office existed previously as the Staff of the Deputy Führer ("Stab des Stellvertreters des Führers") but was renamed after Rudolf Hess flew to England in an attempt to negotiate a peace agreement without Hitler's authorization.  Hess was denounced by Hitler, his former office was dissolved, and the new Party Chancellery was formed in its place under Martin Bormann. Rudolf Walter Richard Hess (Heß in German; 26 April 1894 – 17 August 1987), was a prominent politician in Nazi Germany.  Appointed Deputy Führer to Adolf Hitler in 1933, he served in this position until 1941, when he flew solo to Scotland in an attempt to negotiate peace with the United Kingdom during World War II.  He was taken prisoner and eventually was convicted of crimes against peace, serving a life sentence until his suicide. Titanic is a 1943 German propaganda film made during World War II in Berlin by Tobis Productions for UFA.  Despite the fact that a British company had already released a German-language film about the  in 1929, the film was commissioned by Nazi Propaganda Minister Joseph Goebbels with the intent of showing not only the superiority of German filmmaking, but also as a propaganda vehicle which would show that British and American capitalism was responsible for the disaster.  The addition of an entirely fictional heroic German officer to the ship's crew was intended to demonstrate the superior bravery and selflessness of German men as compared to the British officers. Deputy Führer (German: "Stellvertreter des Führers", more faithfully translated as "Deputy "of the" Führer") was the title for the deputy head of the Nazi Party.  The only person to ever hold this title was Rudolf Hess.
