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 man picks up his duffel bag and swings it over his shoulder, but does not use its strap. He runs through the woods, and the strap is over his shoulder. Just before he runs onto the beach, he swings his bag over his shoulder, as if he does not use the shoulder strap in the woods. (00:01:40)
Continuity mistake: At the start of the movie when the guys are arguing on the porch the guy on the ground suddenly appears to be off the porch in the next shot on the ground.
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: The clock on the wall at Pee Wee's Pawn Shop advanced from about 12:00 to 12:05 when Frank was talking to Jerry, but it was back to around 12:01 after a few camera shifts. (00:05:59 - 00:06:24)
Continuity mistake: The tattoo artist is almost finished drawing the American flag on the boy's upper right arm. After he wipes it and there's a quick camera shift, the tattoo is less complete - the stripes are bloodier, more jagged, and of unequal width like they were earlier. (00:14:31)
Continuity mistake: The "Santa" carrying the Molotov Cocktail walked up the steps and past the decorated handrail, but he was standing within the length of the handrail (about mid-way) when the camera shifted from the right-rear to left-rear side. (00:02:40)
Continuity mistake: The way Banshee's bangs are combed back vary a few times in a couple minutes (elevator fight scene). Sometimes, the left side is higher than the right side and other times the highest point is near the middle of her forehead. The "curve" at which the bangs are combed toward the right side also vary, from little to no curve to wavier toward the right. (00:06:36 - 00:07:57)
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: When Cage backs the silver Porsche into a car while trying to escape the people "following" him and Javi, you see a broken taillight lens fly through the air. You see the back of the car when they drive into the compound and both taillights are intact.
Continuity mistake: While the 2 main characters are playing pool the balls keep changing position and so does the cue chalk. (00:14:00 - 00:17:00)
