Continuity mistake: Katie has been grounded, and like most teenagers decides to just drink up a lot of booze. She's sitting on the bedroom floor with her bestie and passes her the bottle of vodka: her friend takes it with her left hand and drinks, but in the following shot she's finishing the gulp by holding it in her right hand instead.
Character mistake: Reina asked Cory if they could "do that thing" because it was helpful for her medical school training. Reina then put a raw slab of steak/meat across his forehead and made slits in the meat as well as jabbed at it. A medical student studying to become a brain surgeon should know about and practice the safe handling of raw meat. (00:23:10)
Character mistake: Casey is sixth of six male students standing in a row to individually demonstrate a karate move for Sensei. After the fourth student, Sensei passes up student #5 and says, "Next. Casey." Sensei completely missed the fifth student, the only other beginning white belt like Casey. (00:28:45 - 00:29:10)
Continuity mistake: Mario was chewing a mouthful, then lifted his drink to wash down the food, but when the camera shifted, he was back to chewing a mouthful. (00:01:59)
Visible crew/equipment: When Erick asks Sam what she's reading, the shadow of the camera can be seen on the wall next to him. (01:27:51)
Continuity mistake: The front view of Sheriff Garrett [Ethan Hawke] while he is talking to Billy shows a stone-walled well between him and the cabin door, but there's no well visible in the rear view. When Billy walks out with his hands up, there appears to be a well to his right (where the horse rail should be visible), but there is no well when Sara and Rio exit the cabin. (00:14:04 - 00:15:10)
Continuity mistake: The way Linda holds her coffee cup changes numerous times, often instantly with front versus rear views. The handle switches (changes 90° or 180°) from facing towards her chest to her left knee to opposite her chest while holding the cup between her bent knees, which vary in distance apart. The cup is held a few inches above, below, or about even with her kneecaps. (00:44:35 - 00:48:23)
Continuity mistake: At the beginning of the movie, the girl gets assaulted from the back: you see at first exactly from the shot from behind that the backpack she is carrying escapes her arms, but in the subsequent shot she is still holding it. (00:02:10)
Continuity mistake: When George gets shot, he lies flat on his back. When Gloria walks in on the scene, there's a closer view of him and he is lying on his side. (01:18:45)
Deliberate mistake: When Tree turns on the magnetic medical equipment, it's somehow strong enough to yank a big, heavy wheelchair up and pin Gregory in only a split-second, but not strong enough to instantly pull the screwdriver out of Tree's hand? Obviously this was done so Tree could have a cool moment where she lets go of the screwdriver and it impales Gregory... but it makes no real sense.
Suggested correction: It does make sense. The wheelchair wasn't secured and contained lots of metal, so it was immediately pulled towards the scanner. The screwdriver had a lot less metal, and Trew was holding it very tightly, and she knew what was about to happen, so she should strengthen her grip even more, allowing her to keep hold of it.
Preposterous. Depending on how they're set, MRI magnets can yank entire hospital beds clear across the room, and even once killed a man by setting off a concealed gun he was carrying. There's no way she was holding onto that thing.
Revealing mistake: Grace set and held her knees twice onto the smoldering logs on the fireplace hearth extension. There was no indication either time that her pants' knees caught fire. There were not even any sparks/ashes flying from the pressure of her knees onto the logs. (01:27:50 - 01:28:27)
Continuity mistake: Zeke is in the kitchen with his daughter. He is checking out Dick's driving license; in the close-up he is holding it with his left hand, but in the following shot, as she asks him "Where'd you find it?" he is holding it in his right hand. (00:10:15)
Continuity mistake: She is walking from the sofa barefoot, but when she puts down the school year book on the glass table you can see that she has slippers with diamond stones on. (00:28:00)
Other mistake: Judy is singing on stage with some showgirls. She is singing into a wired microphone. At the end of the song she twirls around twice, but the microphone does not appear to get wrapped around her. (00:49:35)
Continuity mistake: In Central Park before meeting the toaster client, Peter Sarsgaard in the close-up has 2 tuning forks in his right hand and one in the left, but in the wider shot he has two in his left and one in his right as he picks up the mallet. (00:07:10)
Continuity mistake: Ellen and Joe just got out of the motel room and begin walking towards the marina. Left of frame, a young couple (she has a cap and denim, he has a full carrot top and a bright red plaid shirt, can't miss them) walking up some stairs on the left, going in the same direction as they do, different path. At the next cut, they are walking down the same boardwalk as Ellen and Joe and in the opposite direction. (00:04:30)
Continuity mistake: Gabriela's luggage crashes down the slope into the vehicle of the beefy co-protagonist. During the scene, the bra on the pickup's hood is positioned in an obvious different way (also coming lower onto the fender's arc) between shots. (00:13:00)
Continuity mistake: The tassel on Molly's graduation cap disappears at the end of her speech, then reappears later.
Factual error: Fire extinguishers should be prominently displayed with no obstructions around them. The fire extinguisher was attached to a wall between the door and window, but it was partially obstructed or concealed by (artificial?) tree leaves. It also looked like the tree and plants might have been on a table that sets below the fire extinguisher, which could block the approach (wasting valuable seconds). (00:39:25)
Factual error: The royal parade is supposed to be of the Yorkshire Hussars, but the filmmakers instead borrowed the King's Troop, Royal Horse Artillery, complete with guns. Although the uniform was similar, the Yorkshire Hussars was a cavalry regiment until the Second World War, when it became an armoured regiment. It was never an artillery regiment.
