In 1933, as Adolf Hitler and the Nazis come to power in Germany, actor and comedian Hans Zeisig and his partner, Siggi Meyer, have a successful comedy act at a Berlin cabaret doing impersonations of Joseph Stalin and Adolf Hitler. Meyer is politically active in the Communist Party and through him, Zeisig meets the attractive Dutch communist Frida. Zeisig is apolitical; he's dreaming about a career in Hollywood. He finds the growing political tension an unpleasant nuisance, but Meyer is endangered by the Nazis' power grab. He arrives one day at the theater with a black eye from an attack and says he is going to go underground. Another performer, a Nazi supporter who caricatures a Jewish man, makes a wisecrack about Meyer's black eye. They get into a backstage brawl, fully made up and in costume—the Nazi as a Jew and the Communist as Hitler. The fight careens its way from the dressing room to the stage, with "Hitler" on top of the "Jew". The audience, larded with uniformed Nazis, assumes it to be part of the show and cheers. The situation continues to deteriorate in Germany. Audiences grow dour, and the theater management has to comply with the prevailing Gleichschaltung. Kristallnacht occurs. Zeisig refuses to perform the defamatory act of the stereotyped Jew. When he is told that it won't do anybody harm, Zeisig states, "It will harm me!" He goes onstage clad as Hitler and satirizes him, knowing he will have to flee. Zeisig learns Meyer has been arrested and deported to Oranienburg concentration camp. Equipped with a forged passport, a fake beard and an assumed name, Zeisig leaves Germany and eventually enters the Soviet Union. His goal is still Hollywood. In Moscow, he arrives at the Hotel Lux. Zeisig encounters Frida, who under a different name, has an important position in the exiled German Communist Party. He also encounters numerous historical figures, such as Walter Ulbricht, Herbert Wehner and others, who later became important political figures in East Germany. The apolitical Zeisig has landed in a hotbed of political intrigue; all important conversations are held with the water running to shield them from the ubiquitous bugs. Zeisig wonders if he is in more danger at the Moscow hotel than he was in Nazi Germany. Taken for a ride to an unknown location, he learns his assumed identity is that of Hitler's astrological advisor, a person of great interest to Stalin. Zeisig is taken to Stalin in the only available safe place, the bathroom. Stalin motions for him to come forward, but remain silent. Stalin turns the water on and only then begins to speak. With Stalin's Great Purge underway, Zeisig realizes that his life depends on his ability to placate the leader. Zeisig narrowly escapes one danger after another, revives his friendship with Meyer, and gains Frida's support.
Background
The film's director, Leander Haußmann, grew up under communism in Quedlinburg, Saxony-Anhalt. The film is dedicated to the director's late father, Ezard Haußmann. Hotel Lux was in pre-production more than four years; the script was worked on by two screenwriters. Herbig, a popular comedian, actor, and director known as a perfectionist, required more changes before he would sign on. He found the first versions of the script to be "too dramatic, too brutal," but joined the production after a lighter tone was reached. Herbig said he could finally relate to the character, a clueless comedian. At the Rome Film Festival 2011, German distributor Bavaria Film sold the film to Italian distributor Archibald Films.
