Continuity mistake: The protagonist just approached Dennis Nylon; he asks her about the vintage scarf. Seen from behind, Stephanie's left hand is on the strap of the bag, but in the reverse angle her hand is down. (00:32:35)
Continuity mistake: Dennis Nylon partially undoes the knot of Stephanie's scarf, which is then for the rest of the scene adjusted in a more aesthetically pleasing way (less straight and flat) despite the fact that neither he nor she had a chance to do so. (00:32:45)
Continuity mistake: At the beginning of the scene inside the Dennis Nylon mansion, Emily is wearing her bag on the left shoulder. She sneaks her way inside the "employees only" area, loses her cover (the guy bringing clothes upstairs), still with the bag looking the same, but the moment she enters Emily's office in a rush, she is wearing her bag across the chest, right shoulder strap, bag on the left side. (00:34:00)
Continuity mistake: Inside Emily's office upstairs, Stephanie ducks under the desk when someone walks by. The floor is fully in the dark, and yet when she crawls to the drawers she tries to pick the lock of, there are distinct sunlit areas all of a sudden. (00:34:15)
Continuity mistake: When Stephanie sets the bottle in the wine cooler as the detective arrives, the label with the name of the wine in italics faces the camera. When she walks off and when the detective looks at the table with the close-up, the back label is the one facing the camera. (00:37:00)
Continuity mistake: In the close-up of Sean's phone when the police calls, the time on the top of the screen is 11 AM. When barely 20 seconds later he is telling Stephanie that he's going to Michigan, the screen of his phone is lit and the time is 2:42. The phone also changed hands in the revealing cut. (00:39:50)
Continuity mistake: When the phone rings with the call about Emily being found, in close-up the phone is very close to the wicker basket, in the wider shot there's a big distance to allow Henry Golding to put down his glass in between phone and basket. (00:39:50)
Continuity mistake: In the opening shots of the funeral, Stephanie is holding her son's hand in the first, and his shoulder in the second. (00:41:25)
Continuity mistake: Outside during the funeral reception, Sean and Steph are dealing with Nicky. The camera cuts to the parents of the kid's classmates gawking at the scene, but before and after they can be seen in background through the window minding their own business and chatting oblivious to what happens outside. (00:43:30)
Continuity mistake: When Detective Summerville asks Stephanie how is Sean's grief, Anna Kendrick's hand keeps changing position at every cut; two fingers under her chin, one, two again and in the same shot lowered to her breast, back under chin again. (00:51:05)
Continuity mistake: When Summerville stands and walks away, Stephanie tells him his theory does not hold water; her hair suddenly is combed behind her shoulders, as opposed to the front as earlier. And a few cuts later, when she praises the quality of the local heroin, she puts her hands on her hips, but is shown with her arms open in foreground at the cut. (00:52:25)
Continuity mistake: At dinner in front of the very crunchy Caesar salad, Nicky says he saw his mom, and when contradicted drops an F bomb and storms off. Miles is putting his fork down at the F-U but in the next shot he's holding it nice and tall. (00:54:55)
Continuity mistake: During the conversation on the plane back from London, Emily's hair keep changing position depending on the camera angle. (00:57:00)
Continuity mistake: When Linda Cardellini says "beatific" to the protagonist, her knife points the sharp edge in the opposite direction of the previous and following shot. (01:11:40)
Continuity mistake: When Diana Hyland kicks the box across the floor, she has nothing in her right hand, which is the hand that holds the bottle in the previous and following shot. (01:12:15)
Continuity mistake: Stephanie holds the Squaw Lake shirt that Diana Hyland threw at her; she holds it in close-up with her hands well apart, stretching it. In the wider angles though she holds it with the hands closer and supporting it with her forearms. (01:12:25)
Continuity mistake: Inside the McLanden residence, Stephanie sits in front of the mother and starts "Your daughter Faith..." Jean Smart 's hand is in front of her face, but it's in front of her chest at the cut. (01:16:55)
Continuity mistake: When she's having martinis on Emily's gravestone, when it's Hope's turn to serve them Stephanie walks around the tomb; the lemon twist is in a different spot of the glass between shots. (01:28:55)
Continuity mistake: When Blake Lively's body double runs through the patch of woods towards the lake, the sole of her feet are entirely covered in dirt. When she jumps from the pier though, her feet are much cleaner. (01:33:35)
Continuity mistake: The bloodstain on Sean's shirt is different between the close-up when Stephanie checks on him and when he stands again. (01:45:50)
