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: 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.
Correction: In these two films, Kevin is portrayed as being a pretty smart and even genius kid. And the way these play out, it requires a lot of suspension of disbelief anyways. This isn't really a mistake so much as an exaggeration of showing how smart Kevin can be.
Kevin may be smart, but the point is he recorded his dialogue as his father before the call was made. He didn't know what would be said in that exact order. The operator could have said any other question (date of travel, how many people, or any random information) or put Kevin on hold at the last second. No way he would know he would be asked about a "credit card" at that moment. That was the point of this entry.
Question: How did Harry and Marv know that Kevin would escape through the back door of the Plaza Hotel while waiting for him?
Answer: It's most likely a plot hole, but one possible explanation I can think of is that perhaps Harry and Marv observed from afar the scuffle between Kevin and the concierge and deduced that he would try to flee the hotel from a door that wasn't necessarily being watched by the hotel staff.
Answer: It could also be because the Wet Bandits were planning to break into the hotel through that door rather than the front entrance and just got lucky.
Well, when Kevin got out the door, Harry and Marv were standing as they were waiting before they captured him. Besides, Kevin has been in that hotel a little longer.
Question: What happened to the limo on the curb of the toy store after Kevin got out? Why did the limo driver leave him there?
Answer: During that time, the hotel found out the credit card Kevin used was stolen. So since they were the ones who got the limo for Kevin, it's safe to assume they also called it back.
Answer: When Kevin exits the toy store he doesn't look around for the limo but instead pulls out his map to examine it. This would suggest that Kevin was intending to do some more sightseeing on foot and likely told the limo driver not to wait for him.
When Kevin got outside the toy store, he did look around like he was confused, and after that, he raised his shoulders.
Question: Why can't Kevin just call the police that Harry and Marv is about to rob Duncan's toy chest at midnight instead of stopping them himself?
Answer: There is no reason other than it would be an incredibly boring movie if he did that. Obviously that's what one would do in real life, but if one buys that Marv and Harry can survive the multiple fatal traps they encounter, then one can suspend disbelief enough to accept a questionable decision to advance the plot.
Answer: I think it's the same reason he didn't call the cops in the first film, he was afraid of the cops because he committed a crime himself. While it could be considered a stretch, it's not really explained in the films. In the first film he is chased by the cop for stealing a toothbrush and in the second film the hotel has found out Kevin was using a stolen credit card, so he flees. Of course, he ends up calling the cops in the first film and makes a recording of their confession for the cops in the second film.
Question: After Peter yells at Kevin "You spent $967 on room service?!", where does Kevin run off to? It's not clear from what's onscreen.
Answer: He's heading back to the hotel most likely to apologize for spending such a huge amount.
Answer: It's Kevin's dad who screams out. You can tell because Buzz looks at the bill, smirks, and says, "Oh, Dad." I've always interpreted it as Kevin running away. The joke is that Kevin's dad screams so loud from the hotel room that Kevin can hear him from the park. So Kevin wouldn't want to face his dad.
Question: How does Kevin manage to keep quiet the events of the first Home Alone movie involving Harry and Marv without anyone else in the family knowing, especially the parents? I imagine that Kevin would've had to take time off from school to testify against Harry and Marv in courts. And even if the trial took place during the summer months, I would think Kevin's parents would have had to consent, or at least have knowledge, to their son testifying in court against the two burglars.
Chosen answer: Remember that Kevin didn't give his name, nor did the police ever see him. When he called, it was from a different address and he gave his name as "Murphy." There is no reason to think that Harry and Marv would tell the police about Kevin, since they would have to admit being outsmarted by a child and also admit to kidnapping, assault, battery, and a wide array of charges for what they tried to do to him. Even if he did testify, there is no reason to think his parents wouldn't know.
And by the way Kevin knew nobody would believe him.
Not entirely correct - He rang the Police from the phone in his parents bedroom just before the spider scene.
Answer: Harry and Marv were career criminals, who expect to spend some time in jail or prison. Considering how they were caught and the police being able to link them to burglaries where the water was left running, it would be likely that they pleaded guilty (meaning there was no trial or need for anyone to testify) in exchange for a shorter sentence.
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.
Correction: Kevin doesn't stop the tape at "Cliff," he stops it at "I could go on forever, baby." There is a pause, but only in the dialogue of the guy on the tape. The fact that the bellhop was named Cliff is a funny (and intentional) coincidence.
Actually, Kevin stops the tape after "Cliff", and then after seconds go by where everyone looks at the guard Cliff, Kevin continues the tape where it says "I could go on forever baby." The fact that Kevin would even stop the tape after "Cliff" in the first place could be submitted as a mistake since he never met Cliff before this point and would have no reason to have stopped the tape there in the first place. The original recording of the movie had no pause between the two lines.
