Corrected entry: When Kevin rolls out his "Operation Ho Ho Ho" plan, similar to the "Battle Plan" from the first film, the printing on it looks to be done by a very young child, with backwards letters, even. But later, when they show the note he wrote to Mr Duncan (the one he wrapped around the brick he threw through the window) the handwriting is much neater - and even a little feminine.
Corrected entry: On the morning the family leaves for Florida, there is a wide-shot of the house. In the next shot, one of the airport vans hits the statue out the front of the house, this statue was not there in the previous shot.
Correction: The statue is there the whole time, but in the first wide shot it's blocked by the lamp with the red bow on it. If you look close enough, you'll see the hand of the statue sticking out to the right of the bow.
Corrected entry: Jeri Ryan (Seven of Nine in 'Star Trek: Voyager', and most recently from 'Boston Public') is the cheating woman in the fictional old movie Kevin watches: "Angels with Even Filthier Souls".
Correction: The actress is Clare Hoak.
Corrected entry: When Kevin records the commercial for the Plaza Hotel, the phone number is cut off by his father's voice. When Kevin is in the hotel later on, he plays the tape and his father's voice is not on it at all and he is able to hear the phone number perfectly.
Correction: Kevin had his Talkboy's microphone pointed directly at the TV, so it captured the sound right in front of it and not his father's voice in the background.
Corrected entry: When the Wet Bandits are stealing the charity money from Duncan's Toy Chest, Kevin takes their picture twice, but only one of these pictures comes out of the camera.
Correction: At least some of the Polaroid instant photo cameras had a photo-sized piece of cardboard before the film and it had to be removed before taking the first photo. If the cardboard was pulled out manually, taking the first "shot" can just be the sound of the cardboard coming out of the camera (which is the same sound as a photo coming out).
Corrected entry: When Harry decides to go into the house, after Kevin has thrown all the bricks, he walks off to the left, past other houses and down an alley. He then tries to enter the house through a window to the left of him. How can that possibly be the right house? He has walked too far and surely the house should be on the right.
Correction: When Harry is walking down the street to the iron gate, he mentioned earlier that he would go around the back to enter the house. What he probably did was go around the block to an alley behind the house but to the left of it if viewed from the front.
Corrected entry: Kevin has his dad's bag, whose name is Peter, and while standing in front of the toy store when Harry and Marv spot him, the bag has "K. Mcallister" stitched on it. It should be a "P" since it is his dad's bag.
Correction: Kevin put his dad's bag in his own backpack. So the backpack belongs to Kevin aka "K. Mcallister".
What about the tag on the bag that Rob Schneider finds while Kevin is first exploring the hotel room, it has Peter Mcalister written on it.
That's the dad's backpack, taken out of Kevin's bag.
The dad's bag was not a backpack. It was a shoulder bag. Kevin's bookbag entering the plane in Chicago and exiting the plane in New York is the same size, but the dad's bag is missing when he walks off the plane.
Corrected entry: When Harry and Marv get hit by the toolchest, Harry asks, "What's that sound?" Marv answers, "That was the sound of a tool chest falling down the stairs." They had not been on the staircase it came from, and had not seen the tool chest or the stairs - both were blocked by the door.
Corrected entry: Just before Kevin's plane to NYC takes off, he puts on a pair of headphones and listens to some music. In reality, passengers are not allowed to use any electronic equipment (laptops, cell phones, headphones, CD players, etc.) in order to ensure no interference in communications between the plane and air traffic control during takeoff and landing.
Correction: Since when do kids follow the rules? Besides, the stewardess could have told Kevin to remove the headphones after the announcements.
Corrected entry: In the scene when Kevin bumps into the flight ticket attendant, he loses his ticket in the pile that falls to the ground. But in a later scene, when Harry catches him jumping off the hotel dock, they pull that same plane ticket out of his jacket pocket.
Correction: A similar mistake has already been corrected. He has round trip tickets and therefore 2 different tickets. And you see him holding the actual ticket to Miami (his boarding pass), as opposed to the American Airline envelope sleeve that both tickets were originally in.
Corrected entry: When Harry and Marv finally catch Kevin after he escapes from The Plaza, Marv looks at Kevin's boarding pass and says 'Round trip to Miami' before tearing it up. However, Kevin didn't have his boarding pass at this stage. While he ended up at the wrong gate due to a man wearing a trench coat similar to his dad's, he lost the actual boarding pass while crashing into the woman at the gate, allowing him to get on the wrong plane in the first place.
Correction: This scene is actually valid, he had a round trip ticket, which means he would have had two tickets, one to Miami, the other back to Chicago.
Corrected entry: When the McCallister kids are all asleep at the Plaza, the shot shows Fuller in the big bed and a few seconds before he wakes up, you hear somebody from behind the camera whisper, 'Wake up.' You have to be close to your TV to hear it and it couldn't have been any of the other McCallister kids saying it because everybody else was sound sleep.
Correction: That is actually the sound of someone snoring. It does sound a bit like words, but it definitely isn't "wake up".
Corrected entry: When the McCallisters are in the airport van, Kate gives Megan her ticket and then Megan and Linnie compare their tickets and Megan asks Kate, 'How come none of us are sitting together?' How would she know if she only compared her ticket with one other person?
Correction: The McCallister's probably have had their tickets for some time and that time at the airport wasn't the first time they saw their tickets. They probably would have had time to ask others where they were sitting and compare their tickets.
Corrected entry: When Harry sticks his flaming head in the toilet, there is an explosion and the scene shows the exterior of the house with the front doors closed. The doors should be open seeing as Marv previously kicked them open before he fell in the hole.
Correction: It wouldn't be that hard for wind or a draft to close a door.
Corrected entry: When Kevin is going up the garbage tunnel for the first time, you see an exterior view of the tunnel wobbling. Off to the left of the screen, you can see a string attached to the curve of the tunnel, which is causing it to wobble.
Correction: This is supposed to be there. The rope (not string) is holding up the garbage tunnel, and is visible throughout any shot of this.
Corrected entry: The reason the family almost miss the flight is because the alarm clock is re-set when the father is un-plugging it to get his camcorder charger. When the clock is disconnected it makes a fairly loud beeping sound. Now, with the parents sleeping just inches from the clock, don't you think they would hear this beeping? They can't be heavy sleepers because the sound of the door-bell is enough to wake them, especially in such a big house.
Correction: I have that kind of clock and it doesn't beep at all when disconnected or when it's plugged back in.
Corrected entry: The toys Kevin buys in Duncan's Toy Chest comes to $23.75 cents. Kevin pays only in notes and the cashier, Mr. Duncan, gives him his change, also consisting of only notes, surely some of the change should have been coins?
Correction: If you look at Mr Duncan when he opens the till, he takes change out the till with his right hand and gives it to Kevin.
Corrected entry: In the swiming pool scene, when Kevin is asking permision from the old people in the pool to jump in, the lady on the chair behind him is there then not there and then there again.
Correction: In the shots with the lady present, we see two chairs with a plant on a table between them, and she is sitting in the right chair (with respect to the camera). In the shots with the "missing" lady, we only see one chair. This suggests that the lady is behind the pillar.
Correction: Kevin only had a little bit of time to draw the "blueprints," so he could have just scribbled and wrote quickly, not paying attention to the writing (and he knew only he would see them). He knew the note would be read by many people and therefore could have taken the time to write neatly - lots of people do that. When it's just them reading something, they don't care; but if they think someone is going to read what they wrote, they watch penmanship and spelling.
