Continuity mistake: The kitchen walls were distorted (at awkward angles), but Zero got to the house around 6:46 and talked to Shelly for a short period of time. The now-blurred clock on the wall appeared to advance to almost 6:47, keeping a reasonably approximate pace with the scene's progress. However, only about 30 seconds passed until Brandon came in, but the clock (no longer blurred) had jumped to 6:50. (00:28:00 - 00:28:50)
Continuity mistake: The first time Tess tries to open the lockbox with the key inside when she gets to the house, the way she is touching/holding it changes between cuts. Specifically, she goes from only having one hand on it to both hands.
Continuity mistake: Young Jake and Drew were at the top of an arched embankment. After they took a couple steps down and the camera shifted, the arched hill behind them comprised three step-like ledges. (00:01:37)
Continuity mistake: The clock on the wall behind Carl when he is pushing the wheelchair to Bess' room is at 11:58. After Carl puts Bess into the wheelchair and is pushing her down the hall, the clock is at 11:45 (or, possibly, 9:00). (00:14:08 - 00:15:40)
Continuity mistake: The placement and angle of the "Not Friendly" sign on the dead security guard's upper right body changes from when Elvis is looking at him down the hall to when Elvis is kneeling next to his body. Initially, the words are perpendicular to the guard's right leg (angled outward to the right), then to the top of his right shoulder. (00:44:45 - 00:45:19)
Continuity mistake: When Will enters Knuckles' trailer, the blinds (behind the lamp) are pulled up half-way on the left side but dangling to the lower right-hand corner. After Knuckles tells Will to "calm down" and the camera returns to Will, the blinds appear to be down on both sides. Also, the gaps between the horizontal slats change from two gaps on the right side to two larger gaps across the width. After Will and Knuckles start fighting, the blinds are pulled diagonally like they initially were. (00:41:57 - 00:42:18)
Continuity mistake: Jimmy's Suburban had a stick-on blind spot mirror on the driver's side (also shown on CCTV when he left the grocery store near the beginning of the movie), but the blind spot mirror was not there when he was driving away to get Natasha on a boat. (01:22:55 - 01:25:58)
Continuity mistake: Henry's scarf is hanging down loosely and appears to be pinned together near the bottom (by his chest). While Henry is running outside, his scarf goes from loose around the front to having an obvious knot over his right shoulder. (00:02:16 - 00:02:43)
Continuity mistake: Overlooking the sudden drop from 1:02 to 0:17 seconds on the countdown clock, the one-second interval beeps are not accurate. In the countdown from 10 seconds, there are approximately or precisely 10 beeps, then the countdown clock shows 4 seconds remaining. (00:19:55)
Continuity mistake: Before Luis Velasquez is killed he is wearing glasses, but from a brief side shot his glasses are gone.
Continuity mistake: Gilbert/Robert was wearing a red pocket square (left lapel) when he was in the phone booth, but not when he came out of the hotel. (00:03:38 - 00:04:36)
Continuity mistake: The positions of the two black SUVs relative to the driveway and garage are different when Justin is reviewing the recording and looks at images from opposite sides. In the first view, the SUVs are not pulled up close to the garage doors; the garage is at least a car's length away because it is not visible to the left of the screen. In the second (opposite) view, the SUVs are parked close to the garage and the SUV that is supposed to be parked near the corner of the driveway is further away. (00:25:30)
Continuity mistake: Stan (Grandpa) gets impaled in his upper left arm by the metal jack part. The front of his jersey's short sleeve is saturated with blood, almost to the orange stripe near his shoulder. Helen goes to see her dad's injury, and Stan's upper shirt sleeve and shoulder are free of blood, but the lower part and his arm are covered. (00:12:09)
Continuity mistake: When the kid is eating cereals in Diana's kitchen, the glass is touching the tablecloth in the first close-up, and it is not in the wider camera angle. (00:31:35)
Continuity mistake: After Ross is shot, he lies on the pavement with his head to the left of the white line, but later his head is to the right of the white line. (His body would not be rotated 180° by police.) His head is on the white line in between this discrepancy. (00:06:38 - 00:09:30)
Continuity mistake: The champagne bottle was behind some candles on the table, but in front of them and in the corner of the table when Danny picked it up. The number and arrangement of the (CGI) candles also varied with close-up versus more distant views. (00:04:42)
Continuity mistake: The handcuff around Ava's right wrist looks loose enough for her to free herself simply by pulling her hand through it. In a later shot, the handcuff is closed almost against her skin. (00:54:30 - 01:00:39)
Continuity mistake: The Hawaiian grandmother was making a speech at the end. One shot shows she's wearing white sneakers then in the next shot she's wearing sandals.
Continuity mistake: Laura's hair was (flipped) above her shoulders when she brought Cody to school. When she was in her car, her hair was much longer, going at least a couple or few inches down her back. Laura's hair was back to its shorter length (above-the-shoulders) when she got to the typing room at work. (00:15:44 - 00:16:06)
Continuity mistake: The mailbox is roughly parallel to Richard's SUV but is more perpendicular when he looks at the address number, then it is back to parallel. (00:06:40)
