Continuity mistake: Smoke was no longer coming out of the wrecked car when The Thief had his back to it while he was shooting at a thug's feet, but it resumed when The Thief turned around to face the car. (00:05:20 - 00:05:43)
Continuity mistake: Before the family went outside, the fire extinguisher was part-way below the window sill. When Peter (father) went inside, the fire extinguisher was away from the window sill (more toward the right of the screen). (00:07:33 - 00:09:12)
Continuity mistake: Ishmael shots Karim in the right side of the stomach, but the wound moves to the left side.
Continuity mistake: Numerous times throughout the movie (largely over the course of one day) Abby's hair was inconsistent within and between scenes. It ranged from neatly combed straight back with no obvious part and a low or higher bun to relatively neatly combed back but angled to the right with a slight or obvious part to messy and frizzy, sometimes with strands dangling in the right front or behind her left ear. With all the "action" going on, she did not have the time or opportunity to comb or fix her hair.
Continuity mistake: The view from the (unseen) car driving toward the distant house on a hill showed fog well above the pine trees, but when the car/limo got to the house/mansion (10 seconds later), there was no fog. (00:02:17)
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: The striped pillow to the left of the screen (behind Nick's beer) is upright, but lowers in the next view. Nobody is near the pillow to move it or push it down. (00:12:36)
Continuity mistake: When Private Connors got out of the front passenger side of the truck, there were no orange "cones" visible in front of the truck, but there was a toppled one after a camera shift that should have been visible earlier. Also, there was a toppled orange cone and an upright one behind the truck, which were not there when the truck was approaching that spot on the road (and would have smashed both had they been there when driving through that section of the road). (00:02:33)
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: 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: When ladybug is sitting at the table with Lemon, and they start fighting over the pistol, Brad Pitt drops the gun's magazine out of the tub onto the floor. In the subsequent shuffle you see the bottom of the gun with a magazine still in it and immediately cut to it on the floor. The next shot after he grabs the magazine off the floor you see the gun with no magazine. (00:40:20)
Continuity mistake: The clock on the wall behind Casey jumped from 10:45 to 11:00 while he was talking to his wife and daughter. At times, the clock appeared to have 3-4 hands and when a hand should have been visible behind his back pointing at "12", no hands could be seen. (00:19:16 - 00:19:46)
