Continuity mistake: The amount of wine in Annie's glass (as well as Nic's) decreases then increases without her adding any. Annie had almost one-half a glass of wine when she poured some into Nic's glass, then it was closer to one-fourth full. A little later, Annie's glass appeared to have the amount she initially had when she approached Nic. (00:13:59)
Continuity mistake: Various views of Chase's dead body were inconsistent. From the two boys' perspective, Chase's body was at the edge of the water and the sun was shining on the water and along/near his left leg. An aerial view showed a canopy of tree leaves over the area, meaning the sunshine would not be able to penetrate the thick tree cover. From the sheriff's view in the tower (unobstructed by trees), the position of Chase's body relative to the fire tower was too far away and at the wrong angle. (00:03:00 - 00:04:08)
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: 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: After Kath pulled up to the cabin, the position of her car changed. Kath drove parallel to the fence before turning to the right about 45° toward the front door, but when she got out of her car, its rear end was perpendicular to the fence. The angle of the shot of Al coming out the front door would also place Kath's car more pendicular to the cabin instead of at an angle, and parallel to the fence instead of at an angle. (00:05:39 - 00:06:36)
Continuity mistake: At the double murder scene, the commissioner asks the eyewitness about the van. In the background, a policeman opens the trunk of the car, fully. He is back in the process of opening it in the next shot. (00:44:15)
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: 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 position of the sunglasses on the dashboard changes a few times. A view from the back seat shows the right temple (stem/arm) reaching between the blue and green balls and almost touching the green one. Later, the right temple is between the red and blue ball and the temple is almost touching the red ball. The temples also go from spread apart to folded/overlapping, with the right lens behind the red ball instead of the green ball where it was. The angle of the camera cannot explain this. (00:03:44 - 00:04:49)
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: 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: Will was not wearing sunglasses when he walked up to Knuckles' fence to look between the boards. When the camera shifted to the opposite side of the fence, the person looking through the boards (presumably, Will) was wearing sunglasses. When the camera shifted back to the side of the fence Will was on, Will was not wearing sunglasses. (00:40:15)
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 amount of pain pills in the bottle was inconsistent and it isn't clear how Carlo could have managed to remove the safety cap (apparently without using his injured arm). After Carlo poured about 12 pills onto the counter, the bottle later looked just as full (if not fuller) as it was. (00:28:03 - 00:28:35)
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)
