- Auteur License: Quentin Tarantino was able to convince The Weinstein Company to allow him to shoot the film in 70mm Ultra Panavision, a format that had not been used in nearly 50 years, and then forgo any digital post-processing or editing. Quentin then persuaded the producers to spend an additional $10 million to equip ~140 theaters around the world with the 70mm projection equipment and optics needed to exhibit the film in a 1950's style "Roadshow" format. Remember, this was several years after even "basic" 35mm film projection had been replaced by digital and most of the 70mm projectors obtained for the roadshow had to be rebuilt from discarded equipment.
- Career Resurrection: For Jennifer Jason Leigh, who was a pretty big name in the 90's and had long since faded into obscurity.
- The Cast Showoff: Both Demián Bichir and Jennifer Jason Leigh performed the music their characters play at various points ("Silent Night" and "Jim Jones at Botany Bay," respectively).
- Content Leak:
- The original draft of the script was leaked in 2014. This caused production to be delayed as Tarantino initially cancelled the project because of the leak but then decided to make it using new drafts which featured a different ending.
- Screeners were leaked a few days before the theatrical run of the film.
- Creator Backlash: Despite his winning an Oscar for his efforts, Ennio Morricone disliked the fact that Tarantino insisted on having him compose a score in two weeks, and the subsequent rush to have it delivered to the director made it an unpleasant experience for him. It doesn't help that Morricone is not a fan of Tarantino's works because he borrows techniques from other films.
- Divorced Installment: The film was originally intended to be a direct sequel to Django Unchained titled Django in White Hell with Jamie Foxx reprising his role as the title character. The idea was scrapped when Tarantino realized he wanted the audience to be more in the dark about everyone's motives and having trouble guessing who, if anyone, was a good guy, and they wouldn't be second-guessing the character if it was someone they were already familiar with (nor would they be that worried about him dying if his name was in the title of the movie). It's likely that Django's role in the movie was replaced by and developed into the Marquis Warren character, another surly black bounty hunter.
- Enforced Method Acting: The guitar, a priceless antique on loan from C. F. Martin & Company's guitar museum, was supposed to be swapped out with a fake to get smashed. But somehow Kurt Russell was never told this, and reached out during the same take and destroyed the real one. Jennifer Jason Leigh's horrified reaction is quite real. (See Throw It In! below).
- Playing Against Type:
- Production Posse: QT's all-stars are on display; Michael Madsen, Tim Roth, Samuel L. Jackson, Zoë Bell, and James Parks all return from prior films. Kurt Russell, Bruce Dern and Walton Goggins (the latter already a member of Robert Rodriguez's neighboring posse) make their sophomore appearances.
- Throw It In!: A particularly bleak example, as befitting a Tarantino movie. Watch closely during the guitar scene: The moment that John Ruth grabs the guitar from Daisy and smashes it, Jennifer Jason Leigh breaks character and starts going, "What?! Hey!! Whoa! Whoa!" That wasn't scripted. As described above in Enforced Method Acting, the guitar that Kurt Russell smashed wasn't a prop, but a priceless museum piece from C.F. Martin & Company; he had not been told by Tarantino to wait until a prop guitar was substituted in before he smashed it. Tarantino left it in, which understandably upset Martin. You can also note the spontaneity in the continuity error of Daisy/Jennifer; when the guitar is smashed, she turns to the crew, facing away from the door, in surprise. The very next shot has her facing John and the door.
- What Could Have Been:
- In what would have been a Playing Against Type for the ages, the part of Daisy was initially written for Jennifer Lawrence. She declined due to scheduling conflicts with both parts of The Hunger Games: Mockingjay. Geena Davis, Demi Moore, Hilary Swank, Michelle Williams, Evan Rachel Wood and Robin Wright were also considered. Katee Sackhoff auditioned, but Tarantino eventually decided that he wanted an older actor.
- More of an idea that was tossed around and ultimately vetoed- Walton Goggins stated that, at one point, the actors and Quentin discussed a post-credits scene in which someone comes across the Haberdashery a week later, finding the corpses of everyone within. Goggins' suggestion for the actor in question was Bill Murray.
- Viggo Mortensen was in talks for Jody Domergue, but had to decline due to scheduling conflicts. Josh Brolin was rumored to have been up for a major role, but nothing came of it.
- Christoph Waltz was originally meant to play Oswaldo Mobray. He was unable to make it so the role went to Tim Roth.
- In the original screenplay the presence of rats in the basement was a common occurrence in the haberdashery. Throughout the screenplay, the sound of rats fighting each other occurs several times and was often a topic of conversation. Also, Jody Domergue was not immediately shot dead after he came out of the basement. In the screenplay, he was shot but not killed, and the rats would eventually eat him alive. The rats were completely discarded and were not in either of the movie versions.
- In one of the earlier drafts of the script, the character of Oswaldo Mobray, was written to appear entirely innocent until towards the climax. During the first major shootout between Jody and Mannix, an unarmed Oswaldo is shot in the chest by a panicking, trigger-happy Mannix, thus making the audience first speculate that he was merely an innocent bystander with no connections to Daisy
- According to the earliest draft of the script, the scene where Maj. Warren interrogates Bob, Oswaldo and Joe Gage about working with Daisy and poisoning the coffee was originally supposed to be more brutal and disturbing than what was shown on film. Instead of simply threatening to pour the rest of the poisoned coffee down Daisy's throat, Warren was written to violently beat her, hold her at gunpoint and then prepares to shoot her in the head until Joe Gage finally intervenes. This scene also had more dialogue.
- In the earlier drafts of the script, Charly was written to be a young orphan boy whose parents were supposedly slaves and were possibly murdered, thus making his demise at the hands of the ruthless Domergue gang much more depressing and tragic. His death scene was also originally supposed to be more brutal and violent.
- In earlier drafts of the script, the death of Gen. Sanford Smithers was more graphic and brutal than what was actually shown. Not only did Maj. Warren shoot the general, but the force of the bullet entering sends the old man into the fireplace where he burns to death. The only reason Warren lets the others pull his body out of the fire is to keep the whole haberdashery from catching fire.
- In the original script, Bob was French rather than Mexican.
