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: 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: 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: After the talk with the police, Sean says he should call a cab and go home. His hand goes from below to the counter, to above it. Likewise, Stephanie checks her watch without and then with her elbow leaning on it. (00:29:00)
Continuity mistake: For the first time at Emily's, Stephanie stops befuddled by the "beaver." When she says "Lifelike", Emily has her blonde hair over both shoulders, but in the next two close-ups there's none on her right shoulder, and then a few locks. It happens again at the end of that part of the scene when she walks away saying "No such luck" about the painting having any value. (00:07:05)
Continuity mistake: Stephanie and Emily are talking in front of the school. Behind Emily, the same person with a red raincoat and pink-red umbrella passes by twice, and when Stephanie says "I think you're joking, but great!" a girl with a red raincoat pops in the view of the door but is nowhere to be found in the next shot. (00:06:10)
Continuity mistake: The first time we see Emily, Stephanie is looking at her open the car door and make her way across the street. Even in slo-mo, it takes a few seconds. But before AND after the sequence, the same dad with a plaid shirt and dark jacket is coming out of the school. (00:04:40)
Continuity mistake: When the teacher asks to the class "Haven't we learned so much about food all over the world?" there's a blonde kid behind her who reaches for a crayon off-screen, then is prominently featured in the cutaway shot where she is drawing already on the paper with it, and then we're back to the same angle as before where she is -still - waiting for that crayon. (00:03:15)
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)
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: Sean hands the "vegetable smoothie" to Stephanie holding it by the middle, which becomes the top in the reverse shot. (00:30:00)
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: 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: Stephanie and Sean have called the police to file the missing person report. The sergeant to conclude the chat asks him "Not planning any more trips?" In the transition between that shot and the next, the position of his hand changes, putting his pen vertical on the notepad in the second. (00:28:05)
Continuity mistake: At the end of the incest story, Emily says "I can't wait to see you cook", suddenly waiting for Stephanie's answer with her hand wide open instead of with the fingers curled by her chin. (00:22:55)
Continuity mistake: Emily says that she can get a bathtub full of perfume to Stephanie, who got quite drunk. As she starts saying that she's sorry about the pictures, she puts on the table her drink using her right hand, but she had just gestured in front of the camera with an open hand in the shot before. In the same scene, the glass jumps back in her hand when Emily asks her "Wanna trade confessions?" (00:18:55)
Continuity mistake: During the sequence where Emily shows Stephanie how to make a 'real' martini, the lemon on the chopping board is turned differently, appearing also more peeled or less peeled, in the various shots. (00:17:35)
Continuity mistake: When Stephanie gives the beads to the Emily, Emily's martini switches hands multiple times, and even the height she holds the glass at changes between shots. (00:17:00)
Continuity mistake: At the park, Stephanie tells Emily "I think you're a supermom", and Emily tells her "Aww no you don't." She has in the second shot both hands joined in front of the crotch as opposed to the earlier position assumed in most of the scene, with the hands in front of her belly. (00:15:25)
Continuity mistake: When Emily says that "Mother Theresa and I are, like, the same person" her fingers are suddenly wrapped around the glass in the second shot. When Sean arrives and Emily chastises Steph for saying "sorry" again, the glass also switches hands. (00:11:45)
