Hans Landa is the main antagonist of Inglorious Bastards.
He is portrayed by Christoph Waltz, who also portrayed Ernst Stavro Blofeld in Spectre.
He is first introduced when arriving at Perrier LaPadite's farm, to seach the residence for any hiding Jews. After he asks permission, he enters LaPadite's house, where he meets the former's daughters. He sits at the kitchen table and asks for a glass of milk, as LaPadite operates a dairy farm. Landa then politely asks LaPadite to send the girls outside, so that they could have a talk. He then asks to switch to English (so that any hiding Jews in the house would not know what they're saying). LaPadite, obviously nervous, asks for permission to light his pipe and Landa permits it.
Landa begins to ask LaPadite if he knows anything about the Dreyfus family, as well as their names and ages, which LaPadite gives him. Landa asks for another glass of milk before he leaves, and then begins to talk about how he loves his nickname, "The Jew Hunter". He explains to LaPadite that the Jews are similar to rats, saying that he doesn't consider it an insult. He goes on to elaborate his statement before coming to the conclusion that his ability to find Jews is far more advanced than that of regular German soldiers', and that he is aware of "humans being are capable of once they've abandoned dignity".
At this point, Landa suddenly asked for permission to smoke his pipe. He pulls out a huge Sherlock Holmes-like pipe. Landa then starts to tell him that in order to cross LaPadite's name off the list, he would have to have his men search his house. However, he tells LaPadite that any information that will make his job a lot easier would not be met with punishment, quite the contrary, it would be met with reward, that his family will no longer be harassed in any way by the Germans during the Occupation. Visibly convinced, LaPadite confirms to Landa that the Dreyfuses are under the floor of his house. Landa asks him if they don't speak English, since he hasn't heard any noises during the conversation.
LaPadite confirms his suspicions and Landa asks him to return to French and continue the masquerade. Hans Landa thanks him in French for the hospitality and for the milk and says that they're now finished. He exits the door, seemingly to call the girls, but he actually calls his men, and points them the place where to shoot. As he wishes to everybody "Adieu", his men shoot through the floor, killing the Jews. However, one girl, Shosanna, somehow survives and crawls through the basement vent and flees in horror, crying. Landa goes to the front door, puts his suitcase on the doorsteps and aims his Walther P38 at her, soon realizing that she's run too far for him to shoot. Instead he smiles and says to himself, sarcastically, "bupsti" (the German equivalent of "oopsie"). Landa then shouts, "Au revoir, Shosanna!", as Shoshanna flees further into the distance.
Hans Landa arrives at the restaurant where Joseph Goebbels, Francesca Mondino, and Frederick Zoller are talking to Shosanna Dreyfus, now known as Emanuelle Mimieux, about her cinema. Zoller introduces Landa to Mimieux, telling her he is running the security for the film premiere. He kisses her hand, while Shosanna tries to remain calm. As the Germans leave, Landa explains that he would like to have a conversation with Mimieux. Zoller rudely asks why, and Landa (both offscreen) is surprised by the private's attitude. Landa then sits at the table with mademoiselle Mimieux. He then orders two strudels and a glass of milk for her. He asks Mimieux about her cinema and if it's true that a negro operates the projectors. When Mimieux confirms that it is, Landa tells her that she will be the one to operate the projectors on the day of the premiere. He then says he had another question for Mimieux and briefly stares at her. After saying he cannot remember what the question was, he leaves.
Hans Landa is called into the village of Nadine, to investigate a shootout between several German soldiers and 2 of the Basterds. He identifies Hugo Stiglitz and Wilhelm Wicki. He tells to the soldier that accompanies him that they were part of the Basterds, responsible for killing German soldiers. But he notices that there's something odd about the incident. He then sees a woman's shoe, and deduces that someone is missing. After signalling everyone to leave, he finds a handkerchief with an autograph from Bridget von Hammersmark..
Hans Landa, is at the film premiere, drinking some champagne. He sees Bridget von Hammersmark with 3 of the Basterds, Donny Donowitz, Omar Ulmer and Aldo Raine, who are masquerading as Italian escorts. He speaks with von Hammersmark and her escorts, and sees through their disguises. He takes von Hammersmark to a private room and tells her to put her foot on his lap. He puts the shoe he found at the tavern on her, and then strangles her to death. He then has Aldo captured, along with another Basterd named Utivich. He takes Aldo and Utivich to an empty building and speaks with them. Aldo asks where Donny, Omar, and von Hammersmark are. Landa tells him that von Hammersmark got what she deserved, and that Donny and Omar are still at the theatre with bombs strapped to their legs. He has Aldo contact his superior at the OSS and negotiates his surrender and allowing the mission to proceed in exchange for immunity, medals, American citizenship, and a house on Nantucket Island. Aldo's superior agrees to his demands and the mission goes as planned, with the theatre blowing up and the Nazi High Command being killed, ending the war. Landa and his radio operator drive Aldo and Utivich into allied territory, and then surrender to them. Aldo tells Utivich to cuff Landa. Landa asks if that's really necessary, and Aldo replies that he's a slave to appearances before shooting the radio operator and having Utivich scalp him, to Landa's shock. Landa finally loses his composure and tells Aldo that he will be shot for this. Aldo says that he will most likely be "chewed out" and that he's been chewed out before. Aldo, knowing that Landa plans to take off his Nazi uniform someday, tells the frightened Landa that he will give him something he can't take off. He then carves a swastika into Landa's forehead as he screams in agony. After finishing, he tells Utivich that "this just might be my masterpiece."
