Continuity mistake: When Lucius is putting aftershave on in front of the mirror, he hears the robot outside and runs to the window, leaving the bottle of aftershave on the desk with the lid off. He returns to open the drawer, and the lid is back on. (01:29:00)

Continuity mistake: The "Denied" word stamped by Mr. Incredible on the paper moves from the center of the sheet to the top, close to the logo.
Continuity mistake: In the beginning of the movie when Mr. Incredible sees the police chase, he checks his watch and says "Yeah, I've got time". Then he has the car put his super suit on. When he sits up and raises his hands to have his gloves put on, his watch is gone. Later, after getting the cat out of the tree, he pulls up his glove to check the time and his watch is back.
Continuity mistake: When Edna agrees to create a new super-suit for Mr. Incredible, she states that Stratogale and Thunderhead were active in the late 50's. In addition, fifteen years after the supers are banned, on the day Dash is sent to the principal's office, the newspaper Bob is reading has a date of 1960-something. However, while Bob is considering Mirage's offer and the camera pans the wall of his achievements, a date on a newspaper says 2000-something.
Continuity mistake: When Mr. Incredible is chasing robbers in his super car and the old woman is trying to get her cat to come down from the tree, she sees him coming quite near and runs out onto the road to flag him down. Cut to inside the car, and the old woman is much further up the road than in the previous shot otherwise he wouldn't have had time to stop.
Continuity mistake: When Bob Parr goes to his boss' office to be told off, you can see the door in the background is closed. Bob gets up and walks toward the door which he has now supposedly opened. You never see it physically come into shot, but when Bob is told to close the door, the shot hasn't changed but you can now see the door in shot being closed, which means the door suddenly opened itself. The framing of the shot never changes, therefore we should have seen the door in shot.
Continuity mistake: In the Parrs' house, right outside the kitchen is the garage (you can see this numerous time throughout the movie). But when Bob comes back late Wednesday night, and when Helen is giving Jack-Jack a bath, when you look out the window, the garage is not there. All you can see is the sky. You should be able to see the garage directly outside the kitchen door.

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: 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.

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.
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.
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: Throughout the entire film Violet's fringe keeps swapping sides.
Continuity mistake: At the dinner table when Dash and Violet are fighting and Bob intervenes by lifting the table, the lamp above is not moving. Even after Frozone comes to the door and Bob lowers the table and they all get back into place, the lamp still hasn't moved. The shot switches to Frozone, then back to the table where suddenly the lamp is moving and Helen reaches up real fast to stop it from moving.
Continuity mistake: When Mr. Incredible opens the window of the RV when the family are flying to the city to save it, you can see lots of paperwork flying about the cabin and exiting the now-open window. However, when the camera does the outside shot of the RV in flight, there's no paper.
Continuity mistake: In the scene where Bob and Helen are arguing after the rescue, when Helen says "Tell me you haven't been listening to police scanners again?", she puts her hand on her head. In the next shot, her arm is down by her side.
