Other mistake: In one ending, Mrs. White is responsible for Yvette's death, yet when Yvette rushes downstairs to meet her killer, Mrs. White is still heard screaming upstairs.
Suggested correction: If Mrs. White was indeed the killer, she could have followed Yvette, then gone into the room where they meet before her. The screaming has stopped before Yvette actually gets inside the room.
That would be impossible. There is no way that Mrs. White could have murdered Yvette because Yvette is seen running down the stairs while Mrs. White is still heard screaming upstairs. Add to the fact that the power to the house had been shut off leaving it in complete darkness, Mrs. White had no way of seeing where she was going and would most likely keep bumping into things. Plus, when Yvette gets to the billiard room, the murderer is already inside waiting for her.
Suggested correction: Mrs. White is not screaming when Yvette is walking into the room (where she is killed) only while Yvette is running down the stairs. Yvette pauses for a brief moment to look into the dining room, then proceeds to the billiard room. There are many secret passageways in the home, and one upstairs could have led into the billiard-room.
Character mistake: During the conversation in the study about who is blackmailing who, Mrs. White mentions two of her five husbands: An illusionist who disappeared and never reappeared and a nuclear physicist who was found dead at home. During the last ending, Mrs. White says "So this has nothing to do with the disappearance of my nuclear physicist husband or Colonel Mustard's work on the new top secret fusion bomb?". However, during the conversation in the study, Mrs. White says her illusionist husband had disappeared and her nuclear physicist husband was found dead at home. So the correct term would be "So this has nothing to do with the disappearance of my ILLUSIONIST husband or Colonel Mustard's work on the new top secret fusion bomb?". (00:21:05 - 01:27:35)
Suggested correction: Ms. White's nuclear physicist husband disappeared too, so the line is right.
Continuity mistake: The Singing Telegram's body position changes when everyone finds her. (01:04:45)
Suggested correction: She was shot, not switched off. She likely didn't die instantly. It's perfectly reasonable that she would move her arm as she was dying.
She died instantly, that is why she collapsed instantly. I am still wondering why they didn't make it look like a real shot, and have blood around the area she was shot at? They made it look as though she was wearing a bulletproof vest and was shot. You can see silver, no blood.
Continuity mistake: When Yvette serves Mrs. Peacock she says shark fin soup but then on 2 occasions later when Wadsworth is going back over how they did it he refers to the soup as a monkey brain, popular in Cantonese cuisine.
Suggested correction: There's actually 2 separate dishes the shark fin soup and then the monkey brains which is that white fluffy stuff they eat after the soup.
Other mistake: Why on earth would six people from Washington, D.C. be summoned, at night, to a house in New England (as we learn from the opening)? That's a drive of between six and twelve hours depending on where in "New England" it was. Yet none of them remark on the very long drive, or mention staying in hotels, or talk about luggage, or have luggage, or complain about having to stay overnight.
Suggested correction: They are being summoned concerning the blackmail that is happening to them. They have no choice but to go. I don't think any of them were planning on staying the night at Hill House. They were there for dinner and the news about the blackmail. If they have luggage, it is most likely still in their cars.
