Continuity mistake: In the scene where Heather runs through the fairground she grabs onto the back of the Ferris wheel seat and is taken up in the air. Leatherface throws the chainsaw at the cop and the next shot shows Heather coming back down the other side of the Ferris wheel. But she should be on the inside of the carriages as it just spins round on an axis. These kinds of wheels don't "twist" at the top otherwise the rider would just be staring at the inside of the wheel the whole time.

Continuity mistake: After Mary slams Grace's face into the table, the blood on her face keeps changing size and shape.

Continuity mistake: When Jack sets up the motorbike, he pivots the two bars forward and locks them to form the handlebars. A few shots later as Jack looks down at the sensor, you can see one solid handlebar, all the way across. (00:13:45 - 00:14:25)

Continuity mistake: When Dave is shot by Mindy while training, there are two bullet holes in his jacket when he has only been shot once at that point.

Continuity mistake: At the beginning, as Raimund is crossing the bridge in the rain, his umbrella turns inside out, but as it flies away to the river, it is not turned.

Continuity mistake: Billy Taggart gets invited to Mayor Hostetler's office. You see as soon as they sit down that there is a grey/black blanket with a pattern next to Russell Crowe. From this point the blanket changes in shape each time. And suddenly after a couple times back and forth shots between them, the blanket is beige/white. Than finally they switch again and it becomes the first blanket again. (00:18:40 - 00:20:10)

Continuity mistake: When Wanderer and Melanie first start to work together to escape, she walks out onto the balcony above a pool and places her hands on the railing, very close to one of the vertical dividers of the railing. The camera pans down to the pool then cuts back up to her. Suddenly, she is equal distance from the vertical dividers on her left and right, and the doors and windows she just walked through have disappeared behind her. (00:22:50)

Continuity mistake: The Counselor's watchband during the long phone call about choices, fate, and grief with Jefe changes the direction in which it is latched several times throughout the scene. It is quite prominent because it is on the arm he is using to hold the phone. (01:35:00 - 01:40:00)

Continuity mistake: When Ray drives through the fields, the headrests inside the Camaro ZL1 show SS instead of ZL1. (01:22:10)

Continuity mistake: When Max hides under the pig cart, the thermal scan from the ship shows at least 8 or 9 pigs, they barely have room to turn. But when he stands up seconds later, the cart has perhaps five pigs and plenty of space around them. (00:56:00)

Continuity mistake: When The Rock is putting early in the movie he is on the phone, when the shot comes back to the room the putting green is missing. (00:01:50)

Continuity mistake: At the end the guy is watching the video of the man that shoots himself in the chin, blood and bone go everywhere, then it shows the guy and girl walk in but there's absolutely no blood. They would have definitely noticed it.

Continuity mistake: By the end of the film, we realise that the Djinn (in this case an invisible and shape-shifting earthly entity of Islamic lore) has staged most of the film's events as a mass illusion. Meaning, the Djinn is a deceiver and can lead humans into dangerous and even deadly situations, but the Djinn cannot perform physical miracles (or else the whole movie would end almost as soon as it started). At the story's climax, the lead characters, Khalid and Salama, end up in the 62nd-floor penthouse of a luxury high-rise, where Khalid drops Salama to her death from the penthouse balcony, just as the vengeful Djinn intended. However, only minutes earlier, we see that the high-rise building is actually still under construction, and it's stated that the building is months away from completion (its main entrance and plate glass have not even been installed). The Djinn only created the illusion that the building was completed to deceive the lead characters. In reality, without electricity and functioning elevators and hundreds of feet of completed stairwells, there was no physical way for Khalid and Salama to reach the 62nd-floor penthouse suite of the high-rise for the climax scene, even if they were being deceived by illusion.

Continuity mistake: During the opening scene of the film we see two boxers fighting in Julian's boxing club. The fighter in red trunks knocks out the one in blue trunks and is announced the winner. Two men then come into the ring and, between shots, we see them pick up the loser off the floor twice. (00:02:51)

Continuity mistake: After the fake movie intro, the two guys drive to a secluded place where their drop is supposed to happen. "Cheno", the one in the driver seat, has the right hand down his side and the left hand on the right side of the steering wheel in a pretty unique position. But in the reverse shot, it's his right hand on the wheel. (00:03:00)

Continuity mistake: When Ivan invites Richie onto his yacht for the first time, a jet ski pulls into Ivan's close-up, and disappears after it cuts back.

Continuity mistake: As El Camaleon pulls the Cuba Gooding Jr. face off, there's an unshaven neck with a tattoo visible under it. After the cut, Lady Gaga's face (also presumably unshaven admittedly, but not visibly so) comes to light under a mask of visibly lighter skin tone. (00:45:05)

Continuity mistake: When Santana is going to open the bloody written locker, he takes the key off his neck, but when he puts the key in the keyhole, it's around his neck again. Some moments later, when he is talking with Johns, the key is off his neck again.

Continuity mistake: At the beginning of the film when the girl is shot, in the close up there is no debris on her face, but the next wider shot shows her face covered with dirt and other bits of debris.

Continuity mistake: The movie opens with a man walking with a dog by a body of water. He is holding the leash with his left hand and the dog is by his left side. Cut to the next shot taken from across the water, the leash is now in his right hand and the dog is on his right. (00:00:20)
