About 36 minutes in when Ruth's stagecoach first pulls up to Minnie's Haberdashery, Bob comes out to greet them. As he exits the haberdashery, the door closes firmly behind him with the pronounced audible "click" of a latch and stays closed. However, at this point the door had supposedly already been broken and should have required nails to stay closed.

When Major Warren and Bob leave the barn, the weather is blustery with heavy snow and the sky is completely overcast. In the next shot, when they walk to the Haberdashery, the sky is clear, the sun is coming up over the mountains, and it's not snowing.

When Joe Gage offers Six-Horse Judy some peppermint sticks, he does so with his outstretched right hand. In the reverse angle the candy is in his outstretched left hand.

When Warren and OB are talking in the barn, their breath condenses in some shots/angles, but not others.

The metallic head of the bed is seen bending sideways when attached to the rope and yet it is back straight up in the next shots.

Warren says that he and Smithers fought against each other during the Civil War at the Battle of Baton Rouge. The battle took place in 1862, African-American troops first saw combat in 1863.

Given the violent reaction to the poison it was some type of anticoagulant which are all sodium based. This means it would not have survived boiling.

Both blockhouses, the station, and the stables have clearly visible interstices between individual logs. Despite the blizzard outside, snowflakes inside the buildings fall almost perpendicular from the roof down to the floor.

Not only would Major Warren be passing as white if he fought in the Battle of Baton Rouge, nine months before the USCT were officially established, but as a cavalry major of any ethnicity he would not be there. Only Union infantry artillery, and gun boats were deployed at Baton Rouge.

When Joe Gage gets his peppermint sticks, they have green stripes which means they were Spearmint. All peppermint sticks have red stripes.

When Daisy Domergue plays the guitar, she sings "Jim Jones at Botany Bay," an Australian folk song. Although the first printed version of this song appeared in 1907, some experts believe that some versions of it were sung as early as the 1830s.

Several characters mention that Major Warren was in a Confederate prison camp in West Virginia. Soon after the Civil War started, residents of Virginia counties that wanted to remain in the Union broke off from the state and became West Virginia, a key border state for the North. However, the counties south and east of Harrison County, about 2/3 of the state, remained in the Confederacy. West Virginia Confederate troops, who were still technically Virginia troops, captured Union soldiers in West Virginia battles. While West Virginia had no permanent prison camps, it had facilities to keep prisoners for a short time before they were sent on to Richmond. On November 11, 1861, future Confederate General Albert G. Jenkins of Cabell County, WV, captured over 100 Union troops in Guyandotte, and marched them through West Virginia on the way to Richmond. In, 1864 West Virginia Confederates captured Union General E.P. Scammon on the Ohio River and burned his steamer. An Ohio paper said that West Virginia was "just as well stocked with rebels both armed and unarmed as any other portion of the South."

Anytime we see the stagecoach in transit, the road surface has been cleared while the surrounding area is covered in deep snow. As there were no snow plows, and as the snow was falling rapidly accompanied by howling wind, there is no way the road could have been clear of snow drifts. In reality, the six horses would have labored to pull the coach through the snowstorm and the road should have been very difficult to traverse. Instead, it's clear that the road had been cleared of snow by the crew using a snowplow.

It is made clear that the door will blow open if not nailed with two pieces of wood and yet at 53', the second piece of wood is only attached to the door with one nail but not to the door frame when nailed by Chris and O.B.

In several shots, the overhead light at Minnie's is bright and glaring. The place was lit with candles and lanterns. No overhead light are visible, and the blizzard would keep the light to a bare minimum.

When Major Warren shoots Señor Bob, the wrong squibs fire. He shoots him first in the belly and blood shoots out of his heart. He then fires in his chest and blood shoots out of his belly.

The fire always burns with the same intensity, even though Bob only adds one log into the fire. It also doesn't move whenever the door is kicked in.

The way station is far, far too large to have been built in such a climate and would be impossible to properly heat. Even though it is referred to as a haberdashery, there would be no logic for building anything that out in the middle of nowhere way except as a barn. A haberdashery is a retail store that sells men's clothing and accessories, but none are seen.

Judy says Auckland is New Zealand's biggest city. Auckland became New Zealand's largest city in the 1900s, when it surpassed Dunedin.

Judy speaks in modern New Zealand dialect, which other characters comment on. In the late 1860s, European settlement of New Zealand was too recent for that dialect to have developed.

The term "pen pal" is used early in the film. Merriam Webster says the first known use of the term was in 1938.

No African-American would've been a commissioned officer in the Union Army during the Civil War. In 1877, Henry Ossian Flipper became the first African-American to be commissioned a Second Lieutenant in the US Army. He was also the first African-American to graduate from West Point.

The word "paranoid" is used in the film. According to Merriam Webster, the first known use of the term was in 1904.

When Marquis removes his knife from Gage's throat, one can hear the sound of metal rubbing on metal, not skin.

In the stagecoach, after John gives Daisy the beef jerky and John tells Mannix to shut up, Mannix leans over to the Major. The Major raises up his gun without cocking it, but the soundtrack plays the sound of a pistol being cocked.

Modern residential homes are clearly visible in the background of several of large landscape shots, and in shots of the stagecoach moving.

The San Miguel Mountains of SW Colorado look like no mountain range formation in Wyoming, the supposed setting of the film. Additionally, there are trees shown in the film which grow in the San Miguel's but that would not be common (or located) in the film's Central or Northern Wyoming setting.

Oswaldo Mobray asks about the Lincoln letter, stating that he understood that someone on the stagecoach had one. Major Marquis Warren, the one who owned the letter, was picked up along the way and was never supposed to have arrived with Daisy, so there's no way he could have known to ask about it.

Chris removes his hat before saluting the general. On the contrary, one should salute with a hat on.

Several characters say Daisy is condemned "to be hung." The correct term is "hanged." Objects are hung, people are hanged.

Chris Mannix doesn't seem to know whether his horse was male or female. He states that *he* stepped in a gopher hole and fucked up *his* leg, then says he "had to put *her* down."

Mannix uses the word "Calvary" (hill of crucifixions) when he means "cavalry" (horse-bound army).

When Oswaldo is showing Mannix the hanging orders for the prisoner in Red Rock, Mannix hands Oswaldo his cup of coffee. While the two are talking, Oswaldo starts drinking the coffee as if it were his.
