Continuity mistake: When Pierce's wife is walking in her auto shop they pan down to show her red Louboutin heels, then they cut to her walking in her office, and when they show her shoes again they have a tan sole.
Continuity mistake: At the beginning Ava shoots the man's phone out of his hand through the car window. When the car drives away all the windows are intact.
Continuity mistake: When Enola and Tewkesbury approach Basilwether, its lights are on. When they enter, its lights are off. (01:34:30 - 01:35:30)
Continuity mistake: SPOILERS: During the final scene, when Samuel L. Jackson is "puppeted" to lift his arm up to make it look like he's pointing a gun at the SWAT team, the number of laser-sights visible on his chest changes between cuts. In the wide-shot, there's only three, but when it punches into a close-up, suddenly there are five.
Continuity mistake: A pile of drugs gets blasted up with powder flying everywhere yet there's none on the ground seconds later.
Continuity mistake: When Marcus sees his baby grandson, a nurse in the background is picking up a white diaper. In the close-up the diaper is now blue.
Continuity mistake: When Driscoll is walking out to his car with his son, you see the driver's side window is rolled all the way up. When he sees Spenser and goes to talk to him, the window is now rolled down, even though he didn't do anything. (01:22:00)
Continuity mistake: First argument. Leilani shouts "Why are you being so loud right now?", with a hand behind her neck. She does not start the next shot in that position, she puts her hand there only a second later. (00:04:05)
Continuity mistake: The color of Lance's clothes change from a dark tan, brown, or grayish color on the train to blue walking through the train station and riding to Jack's place. Lance also has his jacket on the entire time - until he is at Jack's front door (where the jacket is no longer visible). Jack kept his coat on in the car, his apartment, and to play cards. (00:03:44)
Continuity mistake: The replay of Bart and Andrea's conversation at check-in are not verbatim - at times, only a word or two ("uh", "um", "just") is added, but other times there are parts that simply were not stated. Granted, Bart is practising and his additions are not meant to be a reflection of what was actually stated, but the things Andrea said were on tape and these do not always match. Bart did not ask, "Seven nights?" and Andrea didn't reply, "Yeah. A week, maybe longer. I'm not sure yet. So, you're new." (00:27:14 - 00:28:47)
Continuity mistake: The fragments from the truck's taillights that Cassie smashed with a tire iron were obviously "neatly rearranged" (and looked resized to be more uniform) before showing them after the man drove away. Cassie hit the outer sides of the rear taillights and fragments of various sizes scattered, so all would not settle close together along the bumper. One large fragment from the passenger side flew past Cassie behind the truck and landed about three or four feet away but was not there afterwards.
Continuity mistake: A vast majority of the movie occurs over the course of a single day, so it would be expected that Becky's hair stayed about the same. However, there were frequent fluctuations in Becky's hair's length, how her bangs were arranged, and color (whether the blue streaks could be seen at all or how much at a given time, and if she had dark roots on the top of her head).
Continuity mistake: In the opening scene, the blue car is parked on the far right of the screen or at least one car length from the doctor's front door. Dr. Huggins says goodbye to the couple with the baby, who walk toward their car. After the burglars-to-be (turned robbers) are shown watching from a distance, the camera returns to the doctor's front door. The blue car is now near the center of the screen and it drives away toward the right of the screen - going past the place it had been parked.
Continuity mistake: Bernice's bangs go back and forth between having a small section separated from the rest to not separated. Before she kisses Thomas, her bangs are separated, but combed together when they are done kissing. (00:21:56)
Continuity mistake: After Wes was clobbered and on the floor, he had a long stream of water/mucus coming out of his nose or mouth and his lips were wet when he was standing up, but his lips/mouth/nose were totally dry when the killer put his gloved hand over Wes' right shoulder. (00:33:40)
Continuity mistake: The flatbed truck that Kyle and Swin got in at the onset of their trip is very different when they parked and went to buy rope (but got tape). The truck style is different, the cargo and its cover have changed (tarp is smaller, a different color, and is wrapped across instead of front to back), and the orange cone/cones change locations. (00:06:34 - 00:08:22)
