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.

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)

Sammo ★

Continuity mistake: When Claire drunk-staggers down the steps after Andi left the party, she holds chips in her hand, or does not, depending on the camera angle. (00:57:10)

Sammo ★

Continuity mistake: Andi leaves after Duke's words. He walks down the steps, and Birdie looks at him, drink in hand. Depending on the shot, the left hand isn't or is on the straw. And a moment later Miles and Blanc join back the crowd, and her hands switched place, drink supported by the left and right hand on the straw. (00:56:55)

Sammo ★

Continuity mistake: Addressing "the elephant in the room", Claire springs up from the couch and flailing her arms she shouts "Nothing about any of this is fair." Notice in this full view of the room that her jacket is off the pillow it was resting on in the closer angle. (00:54:45)

Sammo ★

Continuity mistake: Duke tells the others that he is leaving the next day. His girlfriend, on all fours, seems to complain. Duke makes a weird noise, and then in the shot from the top he says that she can stay. However, his grip on the glass is different. (00:54:00)

Sammo ★

Plot hole: Benoit Blanc ruins on purpose the murder dinner party because, allegedly, someone is really trying to kill Miles, and he wants to warn him that it's not a game. But as we know later, Blanc is actually trying to investigate the murder of Andi Brand and he does not really think that Miles Bron is in danger. In fact he is positively convinced that everyone has motives to kill in order to protect Miles and all he wants to be on the island for is to gather clues and investigate. Cutting the game short does not serve his purpose at all, in fact it defeats it. Had he played along, both Helen and him would have had a perfect excuse to investigate. In fact it is a miracle that nobody went back to their rooms right away after that tense moment, instead of being busy with the opening investigation; you even see that they are groaning and complaining and want to leave. The movie explains away most of the other details but none about this.

Sammo ★

Continuity mistake: Lionel and Duke are looking at his phone. Birdie walks behind them saying "Thank God for Benoit Blanc." She passes twice the same spot, Lionel each time holding the rim of the glass in a different way. (00:53:50)

Sammo ★

Continuity mistake: After claiming his iPad, Blanc cautions Miles that "for at least one person on this island, this is not a game." His grip on the top of the chair changes between shots. (00:52:10)

Sammo ★

Continuity mistake: At the beginning of the dinner, during Miles' reminder that a murder will be committed, the movements of the guests don't match from cut to cut despite Miles speaking continuosly (for instance, Lionel in close-up strokes his beard and yet in the next shot he isn't and puts a drink down, and same for Birdie, etc). (00:45:50)

Sammo ★

Audio problem: Lionel learns that the whole Glass Onion runs on the dangerous power source. He tries to quit, but Miles puts a hand on his shoulder and says "Bro, you are not getting out." Edward Norton's lip movement does not match the sentence. (00:45:20)
