Chapter Four (full name Chapter Four - OPERATION KINO) is the fourth chapter of the film.
Archie Hicox, a lieutenant in the British army, is called to meet with General Ed Fenech and Prime Minister Winston Churchill, where Fenech briefs him on Operation Kino, due to Hicox's knowledge of German film culture and history and his fluency in the German language. Fenech informs Hicox that Operation Kino is a plan to blow up the cinema where "Stolz der Nation" will be premiering, as the entire high command will be in attendance. Hicox is told he will meet with the Basterds in the village of Nadine, where he will rendezvous with Bridget von Hammersmark, a German movie star working as a double agent for Britain, and be her escort at the film premiere.
Hicox meets with Aldo Raine and the rest of the Basterds. Hicox, along with German-speaking Basterds Hugo Stiglitz and Wilhelm Wicki meet with Hammersmark. She tells them that the venue has changed from the Ritz to a smaller venue, and attempts to tell them another detail, but are interrupted by Major Dieter Hellstrom. After playing a party game, Hellstrom finally prepares to leave the table, but orders a fancy aged whiskey. While doing so, Hicox signals for three glasses, but accidentally signals using the three middle fingers (Germans signal three with thumb to middle finger). This leads to a shootout where only Hammersmark survives. Hammersmark's wounds are operated on by Raine and the surviving Basterds. Hammersmark reveals that Hitler will be in attendance at the event. Hammersmark and Raine decide to go forward with the operation, with Raine, Donny Donowitz, and Omar Ulmer posing as an Italian stuntman, cameraman, and camera assistant respectively (due to Hammersmark remarking that Germans don't have a good ear for Italian).
Meanwhile, Hans Landa arrives at the bar where the shootout occured, finding Hammersmark's shoe.
- When General Fenech asks Hicox if he speaks German, Hicox responds ironically "like a Katzenjammer Kid". The Katzenjammer Kids are an American comic strip created by the German-born designer Rudolph Dirks, published in the Italian newspaper "Corriere dei Piccoli" as "Bibi and Bibò and Captain Cocoricò". All characters of this comic speak with a fake German accent very bizarre ("Just" becomes "chust", "we" becomes "I", "the captain" becomes "der Captain", etc.).
- According Hicox, the purpose of Goebbels movie industry was to overcome the success of Jewish film producers that dominate the Hollywood scene of that period. In this regard Churchill intervenes as asking him how is Goebbels doing if compared, for example, to the producer Louis B. Mayer (the famous as well as despotic head of Metro Goldwyn Mayer). Hicox responds that he's doing well, but Meyer would not be Goebbels's proper opposite number, as Goebbels sees himself closer to David O. Selznick (producer and talent scout with great insight and talent). Selznick produced some big hits like "Gone with the Wind" and King Kong.
- In the 1963 movie The Great Escape, the Nazi officer Von Luger says: "We have in effect put all our rotten eggs in one basket. And we intend to watch this basket carefully". General Fenech will use the same comparison to summarize the purpose of the Operation Kino.
- Hicox ends the conversation with General Fenech by saying: "Paris, when it sizzles". The phrase is a reference to the homonymous 1964 romantic comedy Paris - When It Sizzles.
- In ruined house, Aldo says that you need not be a strategist of war like Stonewall Jackson to choose a better place than a basement as a place for the rendezvous. Thomas Jonathan Jackson, lieutenant general in the army of the Confederate States during the Civil War, was considered one of the greatest commanders of U.S. military history. Jackson earned the nickname "Stonewall" ("Stone Wall") for having resisted with great determination against the advancing unionists, during a phase of the conflict.
- The top level of the spiral staircase and the bottom level of the outside downstairs do not match: the entry door seen from outside would be on the tavern floor level, removing the need for the spiral stairs and the spiral staircase top would actually be above the street level.
- In the basement bar scene, one of the enlisted men refers to Karl May and says his character is Winnetou. This is a reference to the western-theme adventure books by German author Karl May (1842-1912). Winnetou was a Native American hero in several of the books. May was one of Adolf Hitler's favorite authors.
- However, the gesture of touching the heart and greeting with three fingers the man makes is a anachronism as it was a signature gesture of Winnetou in the movies from the sixties.
- Names on the cards from the game played in the bar include: Winnetou, Genghis Khan, Mata Hari, Beethoven, Pola Negri, Edgar Wallace, GW Pabst, King Kong, Marco Polo, Brigitte Horney and Brigitte Helm.
- At the "La Louisiane" tavern, the German soldiers are seen drinking "schnapps". The schnapps are white spirits made in Germany. The distillate is made from grain, potatoes or molasses and is often flavored with fruit (especially apples, pears, plums or cherries) flavorings, herbs or spices.
- The champagne that Bridget drinks is "Perrier-Jouët Cuvée Belle Epoque", easily recognizable by the presence of anemones drawn on the bottle.
- In the film, a group of German soldiers are playing a game where one has to guess what famous name is written on one's forehead. The note on the soldier played by Ken Duken reads Mata Hari, a Dutch exotic dancer and courtesan who became known for being a double agent for Germany during World War I. This mirrors the role played by Diane Kruger: a famous actress turned double agent for the Allies during WWII.
- The cards of the German soldiers read the names of: Winnetou (Native American hero character created by the German writer Karl May), Mata Hari (Dutch dancer and spy during the First World War), Beethoven (famous German composer), Edgar Wallace (one of the most famous writers of detective novels as well as author of the screenplay of the movie "King Kong" of '33) and Pola Negri (Polish silent film star, also known for his part in the comedy film "Hi Diddle Diddle").
- In the tavern there is a female German soldier. Women could not serve in the Wehrmacht (until the end of the war anyway) so she's most likely a Blitzmadel; her jacket missing is another argument.
- The French version of the song "The Man With The Big Sombrero" heard in the tavern was recorded specifically for the film and is song by actress and singer Samantha Shelton (sister of the Marley Shelton of Grindhouse Dakota). In the video clip of the song (directed by Merit Avis) Shelton perfectly recreates the original scene of the 1943 movie Hi Diddle Diddle by Andrew L. Stone where June Havoc sings the same song, but in English.
- When Eric is seen at the counter he reads "Les Fleurs du Mal" (The Flowers of Evil), the famous collection of poems by Charles Baudelaire.
- The card from Wicki's head reads the name of Brigitte Helm, German actress known for the 1927 film Metropolis by Fritz Lang, while Hicox's reads the name of Brigitte Horney other German actress known for playing the role of the Empress Catherine II in the 1943 movie The Adventures of Baron Munchausen by Josef von Baky.
- Bridget von Hammersmark's first card reads the name of the first ruler of Mongolia Genghis Khan, then when she plays the game again with Hellstrom it says the name of the Austrian director Georg Wilhelm Pabst, Hellstrom's card reads King Kong and Stiglitz's card the explorer Marco Polo.
- In the 1970 movie Rosolino Paternò, soldato... by Nanni Loy, the American soldier undercover, played by Martin Landau, responds to a girl who had asked him the time by indicating the number 3 in the British (index, middle and ring) and blows his cover. Lieutenant Hicox does the same fatal error at the La Louisiane tavern.
- The cigarettes smoked by German soldiers at the Louisiane are: the "Harz" (invented brand, named after a mountain range in Germany), the "Alpin" (brand invented) and "Lyonnaises" (brand invented, with the red packet and black stripe in the middle of the table). On the officers's table, in front of Wicki we see a package of "Deutscher Geist" (brand invented). "Chant Du Coq" (invented brand) can also be see.
- The matches seen on the table at the tavern are the "Front Holzer", while those used with by the Basterds are the "Union Match".
- The shooting script includes a scene where Raine and his men intimidate the veterinarian into treating Bridget Von Hammersmark's bullet wound by shooting 2 of the dogs inside their cages. This scene was apparently filmed but cut from the final print, as during the scene with Hammersmark on the table if you look behind her you can see 2 of the cages with holes in the wire mesh, and blood stains and dead dogs within.
