Corrected entry: When Kevin first arrives in New York and does all of his sightseeing, there is a point where he is standing in front of Radio City Music Hall. He turns his back to it and takes a picture of whatever is across the street. He would really just be taking a picture of the side of a random building; there is nothing picture worthy across from Radio City.
Corrected entry: Why didn't Kevin just throw the camera down to Harry and Marv? He had all the pictures of them robbing the toy store, he couldn't lose anything, and the two thieves would then stop chasing him, as Harry said.
Corrected entry: When Kevin is running away from the hotel staff, he runs into his hotel room and he doesn't close the door, he just opens it and runs in the room. But when the staff reaches the room, the door is shut all the way, and they have to open it to get through.
Corrected entry: No one is seen lining up at the cash register at Duncan's Toy Chest. A place like that would have a whole bunch of people lining up after their conversation was finished.
Corrected entry: Kevin takes his father's backpack to New York, but if its his father's bag, then why does it say "K. McCallister" on the back when his father's given name is Peter?
Corrected entry: There's no way Kevin could have known (when recording as his father) what the hotel reservation lady was going to say, but he got the back and forth dialogue perfect as a recording.
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.
Corrected entry: Why didn't anyone spot the burglars in the fish truck? Someone must have in a crowded place like that.
Corrected entry: When Kevin is in his hotel room in the Plaza and hears a knock on the door, which is Mr. Hector the concierge who says (with a German accent) "Housekeeping," he runs into the bathroom and turns the shower on full. The next time we see him he has set up the blow up doll and a pulley system in the bathtub/shower. He is 100% dry. How did he set up such a system under running water without getting wet?
Corrected entry: In the scene where Tim Curry sneaks onto Kevin's hotel room, the time difference from where he knocks on the door until he arrives at the bathroom surely isn't enough time for Kevin to inflate the clown. And there is no point in inflating the clown beforehand, because how was he to know someone would sneak in? (00:35:55 - 00:37:15)
Corrected entry: When Marv kicks open the front doors to Kevins' uncle's place, the doors slam into the walls and stay still. They don't bounce back
Corrected entry: When Marv goes to wash his hands after being covered in paint Kevin is supposed to turn the electricity on. If you look closely he actually turns the switch off.
Corrected entry: Harry and Marv could easily see that Kevin was taking their picture with an instant camera. But later Harry asks Kevin to give them the camera, even though the pictures he wants wouldn't be in it.
Corrected entry: When the hotel staff burst into Kevin's suite, he plays back the gangster movie soundtrack, and it's directed at the nasty bellhop. The gangster reads off a list of people that this bellhop has supposedly been smooching with. When the gangster says Cliff, the tape stops because the old security guard is named Cliff, and we see his reaction. But Kevin could not have known this, or even that Cliff was in the other room, or when to stop the tape.
Corrected entry: When Harry and Marv are climbing down the rope to catch Kevin, Marv asks Harry if he is wearing aftershave. Harry tells Marv that the rope is soaked in kerosene. Marv then says, "Now WHAT would anyone soak a rope in kerosene?" Instead of saying either: ...WHY would anyone soak a rope in kerosene? or ...WHAT would anyone soak a rope in kerosene for?
Corrected entry: Kevin's family is going on a trip to sunny Florida. Yet, Kevin's bag is packed with winter clothes.
