Visible crew/equipment: As Wes steps out of the shower and is drying his hair, you can just see the reflection of the camera man in the glass on the right side.
Revealing mistake: When Gerard Butler is driving to the warehouse to find Frank, the speedometer and the rev counter are on 0.
Suggested correction: I could not see Will's speedometer or tachometer (RPM gauge) during his drive to Frank's. What I did see (and believe you saw) was the patrol officer's instrument panel while he was parked along the road using radar. This was before he pulled out to chase Will's speeding SUV, so both gauges should have been on the far left (i.e, on "0"). [00:46:28].
Factual error: On July 4, Kya waits for Tate, watching the sun set and the fireworks at night. She falls asleep on the shore and wakes up in the same position, watching the sun rise. So the sun sets and rises in the same position. (00:55:40)
Factual error: A .22 shot would be 120-140 dB, muffled with a pillow down to 100-120 dB. Only one person heard the second shot? No one heard the third? Plus at the end there's no way a .22 could pass through a male chest cavity, and halfway into a female chest cavity - it's too low power.
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)
Character mistake: Laura is on the floor, screaming and exhibiting bizarre behaviour, so Dr. Rose Cotter goes to the wall phone to call for help. Instead of maintaining observation and continuing an evaluation of Laura, the psychiatrist faces the wall while making the call and even stares at the wall for a couple of seconds after hanging up. A patient's body language can/do help make a diagnosis, so the psychiatrist should keep her eyes on Laura. (00:11:20)
Audio problem: When Trevor is explaining to Riley how he wants to rob the storage unit, at one point there's an over-the-shoulder shot where he says "Totally anonymous... nobody's ever seen any one in there... but, like the shit..." If you look closely, you can tell Trevor is saying something completely different. True, his mouth isn't on-screen the whole time, but his jaw movements and his mouth movements don't match the words at all when they are visible, revealing they altered the dialogue in post.
Plot hole: It doesn't make sense for the prosecuting attorney to agree to accept a guilty plea from Danny for assaulting an officer, possession with intent to distribute, and resisting arrest with no accompanying guilty plea for at least a lesser-included offense of murder (such as voluntary manslaughter). A violent gang member committing an initiation murder while out on parole would be dealt with much more harshly, especially when the murder victim was a high-school-aged teenager and random victim. (00:09:34)
Revealing mistake: Max rolled down the front passenger side window and no wind came into the car, but when he had his face barely out the window, his hat blew off (not shown on screen). If wind hit the visor part of his "bugout" hat, the hat would have most likely blown off into the car. (00:03:40)
Continuity mistake: Riley puts the red hard-covered book and two others into the box, but puts the same books into the box when Gabby starts to help. (00:13:35)
Revealing mistake: Diana needs to make herself a new DIY cane. She tried to break a few branches, and one eventually makes a snapping sound - you can see though that it just slips into her hand coming from out of the frame. (01:08:00)
Factual error: Rose's legs were paralyzed, but when she was dragging herself on the floor, she occasionally used her feet to help propel her body forward (and moved her feet downward) - something she would not be able to do if her legs were paralyzed. (00:33:40)
Continuity mistake: The blood that was on Leonard's right cuff disappeared and re-appeared a couple times. When he was cutting the bloody suit, the blood on his cuff was gone. When Leonard looked into the briefcase, the blood on his right cuff re-appeared, but was no longer there when he was sewing the suit's sleeve (or thereafter). (00:31:38 - 00:32:40)
Revealing mistake: Luke points a flashlight along the side of the staircase, but no shadows are produced on the wall from the vertical posts. Luke points the flashlight in front of himself and produces his shadow on the wall behind (and the shadow doesn't look like the way he is holding the flashlight). After Luke goes through the entryway aiming his flashlight ahead, a circle of light is behind him. The power is out, so the flashlight is the only light source - except that used for filming in the dark. (01:03:00 - 01:05:25)
Continuity mistake: Jackie holds her pen as she takes notes. Next, her pen is set on the legal pad and her hands are on her lap (below the table and pen). The camera returns to Jackie, and she continues to hold the pen as she takes notes the whole time. (This allows for other questionable variations that could occur off-screen, if enough time.) (00:38:57 - 00:39:29)
Continuity mistake: Simi enters the bedroom and the upper half of the bedspread is smooth. Aunt Claudia is holding a book with both hands, so she is not touching the bed. The front (somewhat aerial) view of the bed shows that the upper part of the bedspread has multiple ripples. (00:17:55 - 00:18:42)
Other mistake: At the end the camera bulbs would not work as they are electric. This is proven when the music starts after the creature leaves the area. (02:01:00)
Factual error: Doctor Key tells Mary, "If you pose a threat to those around you, we will be forced to keep you here [hospital] longer. That means your son will be placed in foster care." Family members, such as the grandmother and uncle currently taking care of Tony, are preferred before placement in foster care. Foster care is usually considered among the last resorts, not first, and only when there are no suitable family members or significant others to provide temporary care for a minor. [SPOILER: It isn't known that the grandmother and uncle aren't biological relatives.] (00:29:15)
Continuity mistake: While Ben is talking to Eloise, his glass of alcohol is about three-fourths full, but when he lifts the drink to his mouth, his glass is almost empty. (00:07:20)
Continuity mistake: The gingerbread man cookie falls into the coffee cup, and the top is barely below the rim. Looking into the cup, the top of the cookie is much further down but does not fall this fast. The coffee cup is about half-full. Jackson takes a drink. The cookie does not interfere with the flow of the coffee into Jackson's mouth. When Jackson lowers the cup from his mouth, there is no visible cookie. (00:08:20)
