Continuity mistake: When Freddie lies in bed with Mary, she has her head on a sketchbook with the Queen logo drawn on it. The sketchbook keeps changing positions between shots.
Continuity mistake: When Newt is straddling Thomas with a knife pointed down at his upper left chest, it's very obvious that the knife goes into his chest, through Thomas' shirt. A few minutes later, when Thomas is kneeling over Newt, after Newt stabs himself in the chest, the stab hole in Thomas' shirt is no longer there and he isn't bleeding. (01:50:45)
Continuity mistake: Right in the beginning, Wade hops out a window from his home and starts walking beside it to the edge to climb to the next level down. As he starts walking he passes by another window with a curtain. It then cuts to a closer angle and suddenly the window no longer has a curtain. Also a wire appears on the wall in front of him. And you can tell it is the same house, not a time jump, as the rust at the top of the window frame is exactly the same. (00:01:15)
Continuity mistake: At the end of The Incredibles, when the Underminer shows up, the Parr family don their masks but are still in their civilian clothes, though Bob is about to take off his shirt. At the beginning of Incredibles 2, in the flashback, as soon as the Underminer appears, they appear in their super suits. Also, the Underminer leaves out "I hereby declare war on peace and happiness! Soon all will tremble before me!" (02:00:00)
Continuity mistake: When Buster is shot, his hat with the hole in it disappears.
Continuity mistake: When the movie begins the smallest boy holds a neat pile of towels. When the shot changes they're messed up. Then they swap back to neat. (00:08:15)
Continuity mistake: When RBG leaves for court (about 30 minutes from the end the movie) her brooch is on the right lapel of her black suit and when she gets out of the cab, it is on her left.
Continuity mistake: While Casey and Morris are video calling, Casey is holding the iPad perfectly and then suddenly it turns upside-down in a later shot. (00:13:35 - 00:14:42)
Continuity mistake: When Lando is rushing over to L3's body, the white panels behind him in the Millennium Falcon pop off from the battle and turbulence. It quickly cuts to another shot where they are still attached to the wall. (01:27:15)
Continuity mistake: Spoiler alert: At the end of the movie "Rose" stabs "Miles." We see her pull out the knife and it looks like a Rambo-type hunting knife. After she stabs him, we see the knife covered in blood but it is a different type of knife. It looks more like a skinning knife or filet knife.
Continuity mistake: The dog poop on the ground moves when the father first pulls his car into the garage.
Continuity mistake: As Steve and Mike are leaving in the police car, Mike turns and puts his arm back as he looks back to start driving in reverse as Steve waves to his wife. It cuts to an angle from behind his wife as Steve puts his arm down, but then Mike turns and looks back again a second time in this shot to start backing up. (00:20:35)
Continuity mistake: This mistake is apparent after watching A Quiet Place 2. At the start of the movie when the family are at the store, a New York Post is visible on the newsstand with the headline "It's Sound." This would suggest that the invasion didn't hit the town immediately and that they had time to have newspaper deliveries and actually put them on sale. However, in the second film, it was evident that civilisation was pretty much destroyed on day one.
Continuity mistake: When Roberta comes over to give Mark the doll he left at the shop, we see an animated sequence just before this. The character in the animated sequence gets her top ripped open. In the real life version, the doll has more of its shirt ripped open.
Continuity mistake: The clock time on the top right of the laptop screen near the start changes from Sun 17:59 to Sun 16:00. (00:08:39)
Continuity mistake: When Charlie is looking through her box of tapes, it shows the columns and there is nothing by Rick Astley. But from a different angle she picks a tape from the bottom of the middle column which we just saw, and it plays a Rick Astley song.
Continuity mistake: During the conversation Nelson is having with Davis about spending more time with animals than people, they are walking out to Davis' jeep and there is a yellow pole attached to the building on the other side of his jeep. The direction of the sunlight is casting a shadow from it on the wall. Nelson and Davis only talk for about 35 seconds, and then the camera pulls back again as Davis begins to drive off and suddenly the shadow from the pole is much longer. (00:12:10 - 00:12:45)
Continuity mistake: In the strip club scene, he goes to the bathroom with his shirt unbuttoned. He reaches into his pocket and starts dialing a number. The angle changes and his shirt is completely buttoned as he finishes dialing. (00:25:10 - 00:25:40)
Continuity mistake: The first time we see Jackson rehearsing, his brother comes to the first row to talk to him, always with his right arm down. There's a brief shot from a different angle where his arm is suddenly up. Then back to the previous angle where the arm is lowered for the rest of the scene.
Continuity mistake: After young Donna and Bill are swimming back to the boat, Donna climbs up into the deck wearing a full face mask. In the long shot we see her turn around still wearing the mask. In the very next shot she sits down but the mask has vanished completely.
