Other mistake: Near the end of the film when Jack-Jack is manifesting various abilities, his first display is of the human-torch-type of superpower. This would have burned away all of his clothing, yet (for obvious reasons) his diaper remains intact. This is particularly apparent as designer Edna Mode's costume for Jack-Jack was earlier shown as fire-resistant, but he was not dressed in his outfit during this scene. (01:44:15)
Suggested correction: This is definitely intentional, not an error. We see Jack-Jack use his fire powers without burning his diaper in Incredibles 2. Having fire powers without burning clothes is just a retcon.
Continuity mistake: When the Parrs are having dinner and when Frozone stops by Dash spits water and Frozone freezes it. In the shot after he catches the ice, the ice disappears.
Continuity mistake: When Elastigirl, Dash, and Violet are in the jet outrunning the missiles, the ocean is very rough. This can be seen when Elastigirl boosts and hits a large wave when she is trying to gain altitude. But, when they are in the water after the missiles have hit them, the water is very calm.
Continuity mistake: In the pursuit at the beginning of the movie, you can see on the navigation screen that Mr. Incredible has passed Adeline St. When he's going to place his supersuit, he looks at the screen and he hasn't passed this street yet. (00:02:35)
Continuity mistake: The objects on the table keeps changing place while Bob is taking notes of Mirage's message. The most noticeable is the piece of paper with a "i" on it. (00:32:25)
Continuity mistake: When Bob is in his cubicle before Mr. Huff shows, the pencil holder is on the left side of the desk, next to the computer. When Bob jumps up, but before the pencil holder's knocked down, it's in the middle of the desk. Then when he picks it up it's closer to the phone, but still in the middle of the desk. As Mr. Huff turns to leave, it's still there. But when the camera cuts to an overhead shot, the pencil holder's jumped to the opposite side of the phone, perched on the edge of the desk, where it falls to the floor. (00:13:15)
Continuity mistake: In the scene where Hugh is coming into Bob's office, you can see, as he is coming in, that the glass separating Mr. Incredible's cubicle from the hallway has two seperate openings. This is visible both immediately before and immediately after Mr. Hugh walks through the doorway. In all other shots, however, The glass is one continuous pane. (00:13:05)
Continuity mistake: When Frozone picks up Mr. Incredible to "go bowling", the green glass lying on the table on the left hand side of Violet keeps swapping sides between one shot and the other - sometimes its open end faces Dash, and sometimes it faces the entrance door.
Continuity mistake: When Mr. Incredible lands on the railway and it explodes, the rubble and debris that falls disappears and reappears between shots. Furthermore, when he stands up to stop the train, the aerial view shows cars driving along the street as if nothing ever fell. With the amount of rubble falling, it should be visible on the street and have caused some traffic problems.
Deliberate mistake: In the Spanish version, the headlines of the newspapers are in Spanish, but the rest of the articles are in English. It helps supports the narration, but it causes a very weird effect.
Continuity mistake: In the dinner table scene, when the family "cleans up" in order to answer the door, Dash's hair is all frizzled and standing up from running around and fighting with Violet. When Lucius shows up, Dash spits some water into the air for Lucius to freeze. Dash then says, "Aww, I like it when it shatters." In that one quick cut, Dash's hair is all neat, almost no hairs frizzled. In all subsequent shots of Dash, his hair's all frizzled again.
Deliberate mistake: In the scene where Helen snags a ride on one of the rail cars (grabs it with her hands then does her Tarzan imitation), one of the support beams for the track magically disappears to give her more space to grab the car. The camera doesn't cut, or even change position- it just pans, all in one shot. When she looks forward at the track, there's one beam a short distance in front of her, and one beyond that. She turns to see a rail car approaching, and when the camera pans back to see her grab the car, the distance to the next support beam has been doubled- the first beam disappeared. (01:16:25)
Continuity mistake: When Bob stands up in the jewelry store, he is right next to a jewel display. When the alarm rings, he's almost two meters away from it. He didn't have the time to move. (00:23:10)
Continuity mistake: When Helen is going to place the supersuits in her luggage, there is a few centimeters between the one that she grabs and the others but they are much closer in the next shot. (01:03:55)
Continuity mistake: When Helen is floating in the ocean, her hair got wet and it straightened out. When she was in the shape of the boat, and after they got to land, her hair was in the regular style; both the water and the strong wind would have caused her hair to be messed up.
Continuity mistake: In the scene with Dash and Elastigirl in the principal's office, Dash's shirt keeps changing between shots. First it has a strange "X"-shaped fold on it, then it changes to relatively smooth, then BACK to the "X", and so on.
Suggested correction: Dash was only bending over and in the next shot he is sitting straight so he unwrinkled his shirt without noticing.
Other mistake: When Helen is packing for the trip to find Bob, she is holding a outfit on a hanger. Watch how the coat moves when she slides it across the bed. Friction should cause the bottom of the coat to drag across the bed and while the top moves forward. Instead the bottom looks almost like something was pulling it ahead of the top. It gives it a very unnatural look.
Continuity mistake: When at the end, the Omni-Droid is walking past Frozone's apartment and he is putting on the aftershave, he turns around looking for his Super Suit and the aftershave bottle turns itself around.
Continuity mistake: When Mr. Incredible and Mirage are having dinner next to the wall of fire, the long shot shows them at opposite ends of a very long table. All of the following close up shots of Mirage, shown over Mr. Incredible's shoulder, show them as being much closer together, at a much smaller table. (00:40:50)
Other mistake: When Bob is getting chewed out by his boss, his boss starts talking about clocks and says "there are also dual cogs." However, the subtitles say "there are also jewel cogs", and the subsequent conversation therefore makes little sense. (I saw this on the collector's edition DVD).
