Revealing mistake: When Warren begins shooting Bob, a massive blood spurt is shown each time he shoots him. Each time he is shot, the blood spurts don't line up with the area where Warren shoots at. The first time Warren shoots Bob, the gun is shown firing at his stomach, but the blood is shown spurting from his chest. The second time he shoots Bob, the gun is fired at the top of his chest, but the blood spurts come from a couple of inches below where he was shot. (01:57:00)
The Hateful Eight (2015)
1 revealing mistake
Directed by: Quentin Tarantino
Starring: Samuel L. Jackson, Kurt Russell, Tim Roth, Channing Tatum, Jennifer Jason Leigh
Genres: Western
Factual error: The bed in the "Haberdashery" has a box spring under the mattress. Referring to a "History of Bedding": "By 1927...box springs with ticking covers were still new." Having one in this time and remote location would have been impossible.
Major Marquis Warren: Move a little strange, you're gonna get a bullet. Not a warning, not a question...a bullet.
Trivia: Towards the end of the movie. When Major Marquis runs out of ammo, in the slow motion scene. The score is taken from John Carpenter's "The Thing", another movie staring Kurt Russell.

Answer: It's not PURELY fictional, as plenty of poisons lead to vomiting and bleeding (cyanide, arsenic, etc.), but Tarantino, as is his wont, definitely takes some artistic license and kicks it up several notches for dramatic/gross-out effect.
