The Gestapo officer in the tavern is depicted wearing an M1932 Allgemeine-SS uniform, a style the SS popularised during the 1930s. A Gestapo operative would not have worn that, particularly by 1944, as its use had been discontinued in 1942. Such personnel would more commonly have appeared either in civilian clothes or in an SS-style grey field uniform akin to Landa's.
Lieut. Archie Hicox utters the line "Paris, when it sizzles," which actually stems from a lyric in Cole Porter's musical Can-Can (the song "I Love Paris"), not written until the 1950s. Porter coined the expression; he did not simply adopt it from common usage.
In the interrogation scene, the Austrian Hans Landa is shown smoking a high-quality Austrian calabash pipe — a Strambach — whereas Perrier LaPadite uses a much smaller, cheaper corn‑cob pipe, an instrument primarily associated with rural pipe‑smokers in the United States. However, corn‑cob pipes were not known or used in France during the 1940s; a modest‑income farmer would more likely possess a simple clay pipe or a second‑hand Jacob clay pipe.
When Landa has Raine and Utivich as prisoners, and is gesturing towards the telephone, the handset is attached to the telephone by a perfectly coiled black cord that didn't exist until after 1960.
The highly flammable cellulose nitrate stock of the era is pivotal to the film's climax. However, in the projection booth the projectors are depicted with their film reels exposed, which would have been utterly unimaginable at the time. In reality, all projectors were enclosed in fireproof metal boxes through which the reels ran. These enclosures had only small windows so the projectionist could check how much film had been run off or taken up. If the film caught fire while running through the projector and the blaze spread to the feed or take-up reel, the boxes would contain the fire long enough for the booth's fire shutters to be lowered and for the projectionists to leave the booth and begin evacuating the building.
At the opening sequence set in France, Landa refers to Reinhard Heydrich as "the Hangman" according to the populace of Prague. The exchange is dated to May 1941, but Heydrich did not assume the post of Reich Protector of Bohemia and Moravia (which encompassed Prague) until 27 September 1941. It is therefore improbable that many Czechs would have been familiar with Heydrich in May 1941.
The massacre of Shoshanna's family shown in the film's opening is dated to May 1941 — roughly a year into the German occupation of France. In reality, however, mass round-ups of French Jews in the German-occupied zone did not begin until mid-1942, while comparable arrests in the zone administered by Vichy commenced in 1943. Consequently, Dreyfus's execution as depicted occurs more than a year earlier than it would have historically, depending on which zone the family were hiding in.
In the opening scene the small convoy winds up the lane to the farmhouse; all the fields are clearly modern arable crops — not pasture as the plot suggests — with 'tramlines' from contemporary sprayers running through the wheat plainly visible.
Throughout the film the distinctive enamel‑adorned Perrier‑Jouët cuvée Belle Epoque champagne bottle appears on several occasions. Although Émile Gallé designed this bottle in 1902, it soon fell into obscurity. In 1964 Pierre Ernst unearthed four examples, and the design was reissued two years later to mark the seventieth birthday of Duke Ellington.
