Continuity mistake: There's a clear mix-up in editing during the car chase. Marta checks her phone twice for Blanc's calls as she tries to get away from the police. The first time the phone signals 9:36 AM, the second time 9:34 AM. (01:31:50)
Continuity mistake: At the end of the car chase, Marta is looking at Blanc shielding her eyes with her hand. When he says "I don't know what he came back to do" etc, Marta's hand is off her forehead, but is on in the shots before and after. (01:34:05)
Continuity mistake: Ransom is brought back in the room for Blanc's denouement by Officer Wagner. First shot he has his hand under Ransom's armpit. Second, Chris Evans' arm is close to the body, no officer hand in sight. Third like the first, hand under armpit. Fourth, the officer is a few steps away and with his arm lowered. (01:46:20)
Continuity mistake: During the explanation of the events, Ransom angrily replies to Blanc "You have her confession" as he objects that there's no proof about the vial switch. Daniel Craig says "All right, yeah" arms down, but in the next shot he is shown at the edge of the frame during Marta's closeup, and his arm is bent. During that close-up Ana de Armas ' hair is also differently spread over the shoulders compared to the following view. (01:52:10)
Continuity mistake: Blanc says he has no idea how Fran got hold of the toxicology report; in that shot, wide angle, Marta's hair cover her right side of the collar of her coat, like in most of the scene. But in the close-up that follows, when she blurts out of the reason, her hair is on the inside of it. (01:54:10)
Continuity mistake: During the denouement Marta asks "So why did she send it to me?", and Benoit Blanc replies with his right hand in mid-air - but it's in his pocket at the beginning of the next shot. (01:54:30)
Plot hole: The killer shows up at the scheduled appointment at 8 AM. They kill the idiot blackmailer with an overdose of morphine. Remember, that morphine that supposedly killed Thrombey in 10 minutes. Marta finds the blackmailer at 10 AM...alive, and does CPR on them, keeping them alive long enough for the ambulance to come and bring them to the hospital, even if in critical condition. So we went from "kills in 10 minutes, you can't even try to save him" to "after 2 hours, you are still hanging on"? (01:56:10)
Suggested correction: Marta injected an absurdly large dose. A smaller overdose would not kill in 10 minutes.
I read that objection before. From 10 minutes to 2 hours there's quite a leap that the movie does not explain or address at all, if it were part of the plot they should have said why this difference, on something so time sensitive (of which they got the factual details wrong anyway). Even visually when you look at the dose injected to Harlan and the dose in the syringe for the murder, they do not look different. He even stabs her with the syringe. Which makes sense since he has no reason to leave her there with a small. Controlled overdose in her veins risking that she would be saved as it -almost - happens - it's amazing he got away with it to begin with because she is so dumb to show up for no reason in a derelict place without talking to her accomplice that passed her the toxi report, or anyone.Without a throwaway line from an investigator or anything of the sort ("but you injected her the wrong way, so she was still alive two hours after"), we are just left with an inconsistency.
Suggested correction: You've assumed a hell of a lot! Marta said Thrombey was given a dose of 100 mg (instead 3) of Morphine and would die in 10 minutes unless given the antidote. You just asserted that "Thrombey would die in 10 minutes" as if it was fait accompli, while Thrombey didn't die of morphine overdoes at all! (He cut his own throat.) For all we know, Marta's 10-minute assessment was a worst-case-scenario assessment. Fran's age and physique, as well as Marta's CPR, helped negate the effect until the ambulance arrives. If the medics administered the antidote, it could have prolonged Fran's life. Finally, 2 hours is the time after which the viewer is informed of Fran's death, not her actual death time. Most importantly, this happens in the medical world all the time: A person who is supposed to die after 3 days lives for 16 years. There are case-by-case explanations for each one, but they baffle the medical examiners at first.
Two hours is not my assumption or when the viewer is informed of her death; the killer gives the appointment to the victim at 8 AM and to Marta at 10 AM, so as I said, after 2 hours with 0 medical care on her she is still hanging on and with barely a little tap she is ready to dispense important clues. I go by what the movie says also about the 10 minutes overdose time. Of course if you tell me that baffling freak occurrences can happen all the time in medicine and that very precise statements from the movie don't matter because the character can just have gotten it wrong by over 10x and the movie does not acknowledge it at all, well, that's a very respectable opinion; mine is that fiction (a whodunnit, not a slasher flick with a killer surviving multiple gunshots and the like) is not reality and it should respond to higher standards than "I guess she was still alive somehow."
I re-watched the movie to verify that Fran was given an appointment at 8 AM. I discovered something new: The bottle that was injected to Fran contained only 5 mg of Morphine. That's 1/20th of what was "supposedly" given to Thrombey Sr. So, yeah, 10x is OK. In fact, 20x is OK.
No, no; it contains 5 mg of morphine PER ml, it's the concentration, not the total. Go back to the scene when Marta "messes up", the vials are the exact same as the one that Ransom injects (obviously, since they come from Marta's bag after all). It's new for you but I covered that already in the Factual Error about it. It's something that piles upon a previous mistake. She did not give him 100 mg of morphine because it would have emptied the vial (which is more than half full) and because a full vial of ketorlac would have killed Trombe regardless, at that concentration! The movie gets both the props and the medical facts wrong (100 mg of morphine does not even kill most patients, Harlan would have not died in 10 minutes especially since he takes safely big doses of toradol and morphine), but nothing - in the script - says that Marta or Ransom got basic medical facts wrong.
Okay! It seems mistake after mistake is piling up. Now, it appears Fran lived 4 hours, during 2 of which she was unattended. Plus, 100 mg of Morphine from a 5 mg/ml vial amounts to 20 ml of liquid. Well, now, everything you say makes sense... or at least most of the things. On the whole, I think it was a complicated situation.
Other mistake: During the revelation of the second death, when the killer opens the toxicology report they just retrieved, the date is revealed; it says it was issued on 09/27/2018. But the events of the movie happen in November (it's Sunday 18th Nov when Marta wakes up with all the reporters at her door). It should also be noted that when a close-up of the report was shown earlier (when Ransom was looking at the anonymous letter brought by Marta) that copy had a big stamp in a corner saying 11-17-18, that in this copy is totally absent. (01:56:55)
Continuity mistake: When Ransom asks "Fran's alive?" to Blanc, Chris Evans has his hand raised, thumb before his lips. But the hand is lowered in the shots before and after. Similar situation when the word "Jail" is used a few seconds later. Hand visible in close-up, not matching the wider angles. (01:58:10)
Continuity mistake: The quantity of barf on the killer's face varies between shots - in particular they have a big reddish bit on a cheek that disappears in the dramatic slo-mo side view when they push Marta down, weapon in hand. (02:00:00)
Visible crew/equipment: While Blanc talks to Marta about how long he has known her to be involved in the case and that he has an opinion on whether she should help the family, a person (most likely a crew member) leaves the house in a stooped position, as all the other inhabitants should have left it by now. (02:04:19)
Visible crew/equipment: Marta and the detective are driving to the 1209 location, and he is talking. During this entire scene, the reflection of the camera is visible on the left side of the glass.
Continuity mistake: When the detective (Benoit) asks Marta to be her "Watson", the wind is blowing hard enough to move their hair. In the reverse shot, it is calm.
Revealing mistake: The detectives start interviewing Linda and tell her they will be recording it. The detective pulls out a phone, and we see it recording. He starts talking and the waveform is moving but doesn't match when he speaks. If it were accurate we would see a peak when he talks.
Visible crew/equipment: During the car chase, Marta pulls her car into a dead end and the camera moves up to the window. The top of the camera operator's head is visible in the reflection. Later in the same shot, the camera is visible in the glass left of screen.
Continuity mistake: As the camera is panned wide with an aerial view of the estate there are no leaves on any of the trees. But as Marta steps out of her car, the trees are full of very colorful leaves.
Audio problem: After Harlan knocks over the Go board, Marta says "I'm done with you." When she says that, which is when she puts the two vials on the table, her mouth isn't moving.
Continuity mistake: When Ana runs out of the gates in the back yard they're left open, but when Ransom returns at 3 am they're closed. And even though it hasn't rained for a week it is still muddy.
