Continuity mistake: In the flashback, "Andi" is dead with her right arm on the last step in most shots (as she was the first time we saw the scene) or the one below (like when Blanc is crouching and curses saying "Sh*tballs." (01:45:20)

Sammo ★

Other mistake: The way Helen and Blanc clash into each other during the blackout differs radically between the first time and the lengthy flashback; in the flashback she is calling his name, and he tells her "There's great danger." Neither happened the first time we saw the scene. (01:07:00 - 01:43:20)

Plot hole: In the flashback, Whiskey fired the speargun at Helen at the bungalow away from the main house as she was fleeing at the beginning of the blackout. She has no light source with her, but somehow in the earlier showing of the events she was one of the first people to pop up at the party room seconds after the blackout started, and with a loaded speargun. (01:06:00)

Sammo ★

Continuity mistake: In the argument between Birdie and Peg that Helen happened to record, Kate Hudson's hands are in a different position in her lap in the reverse shots when she says "There's no stopping it" and just after she admits "It's my secret phone." (01:37:25)

Sammo ★

Continuity mistake: In their bathroom consultation, Blanc compliments Helen about the 'interesting stuff about Whiskey'; he is leaning on the sink, and then suddenly he's gesticulating with that same hand. (00:01:29)

Sammo ★

Continuity mistake: Whiskey is walking with Helen towards the pool. When they are under a colonnade, the Taurus pendant shifted towards her left pectoral much more than it was in the previous shot. (01:26:50)

Sammo ★

Character mistake: In the flashback, Blanc tells Helen that when Miles will pull him aside to explain his presence, that is when it will be her chance to 'snoop'. However, that piece of dialogue is just unnecessarily wrong since the whole distraction with Miles lasts just a few minutes, does not facilitate at all her snooping, and all the other guests are in their rooms just unpacking and hanging out. If anything, Miles keeping the other guests entertained and gathered together is what would facilitate her. (01:25:45)

Continuity mistake: In the flashback, Helen tells Blanc as he kneels to tie the shoelace "Duke and Birdie, I think they're onto me." Notice the sunglasses poking from the top of the frame, and the right hand that moves away showing that the shades are in her left hand. But it cuts back on her in a shot from the waist up and her glasses are in the right hand. (01:25:35)

Sammo ★

Continuity mistake: The night before the boat trip, Blanc tells Helen "This is your last chance to back out"; his forearm for just that shot is on the back of the bench. (01:24:55)

Sammo ★

Continuity mistake: Andi topples the shelf and various books fall off scattering on the floor. In particular, "The Innovator's dilemma" is propped on top of a different open book. In the close-up where she pulls the napkin out of it, the book shifted without anyone touching them. (01:23:30)

Sammo ★

Continuity mistake: When Helen shows Blanc the notepad where she drew the Clue-style tab, the letters are drawn in a different way from the close-ups (most obvious hint; the M for motive does not touch the grid). (01:24:20)

Sammo ★

Continuity mistake: Debriefing Helen at the restaurant the night before the impostor game begins, Blanc tells her how to behave on the boat. Her hands are off/on the table between shots. (01:18:45)

Sammo ★

Stupidity: The whole premise of the plan is summarized by Helen in the sentence "They don't know Andi is dead, so why would they suspect anything?" However, "they" conspired in unison to financially ruin her sister, and "they" did not answer the mail, none of them. The possibility that "they" all could have gathered and silenced her by force is one of the most likely ones, and yet neither she or Blanc consider even for a moment that the literal crime conspirators could have conspired.

Sammo ★

Continuity mistake: At the beginning of the retelling of the story, Blanc holds Helen's phone in his right hand, and yet the close-ups are of a left hand. (01:13:40)

Sammo ★

Continuity mistake: Throughout the conversation with Helen on Benoit Blanc's terrace, her facemask switches position between two distinct spots on the table. (01:11:00)

Sammo ★

Continuity mistake: Blanc says "Where's Duke's phone?" holding his wrist in the closer angle, but his hands weren't there in the previous wider view. (01:04:05)

Sammo ★

Stupidity: The Disruptors have been close friends for well over a decade, and one of the other guests is Duke's girlfriend who has been living with him for at the very least one year (she was at the previous meeting). Yet nobody seems to have the slightest suspicion or recollection about his pineapple allergy, so lethal that it kills him in a few seconds, even more amazing considering that the favourite drink of one of those drinking buddies of his (who is sitting on his lap in one of the flashbacks) is exactly what would kill him; the topic of contamination surely must have been touched upon. (01:00:00)

Sammo ★

Continuity mistake: Duke falls back on the glass table and spasms. His left hand is on top of the right one, but as he rolls over the hand switched place. (00:59:50)

Sammo ★

Continuity mistake: Miles fixes himself a drink saying "fake it till you make it." He then joins the others, but look at Birdie Jay and her assistant; completely different poses between shots - Kate Hudson is even dancing with and then without her massive glass. (00:58:40)

Sammo ★

Continuity mistake: Miles seems to have pep talked his friends into staying for the rest of the weekend after the momentary crisis brought by the premature end of the murder mystery. He says "You're staying" to Lionel, who is holding his glass with both hands, then suddenly with one hand, the other hand being on his knee. (00:58:25)
