Continuity mistake: In the first film, it is mentioned several times that Kevin is 8 years old. However, in this film it is stated that he is 10. When his parents are in the Miami airport security office, they say that he was left alone last Christmas. That would make him 9. Both films take place the same days, from about three days before Christmas until Christmas morning, so even if Kevin is born around Christmas time this is still a mistake.
Audio problem: When Kevin plays the tape of his Uncle Frank singing in the shower, it starts with "We know a guy that can really do the cool jerk" twice. Yet, when he first tapes his Uncle, he doesn't start the recording until after that has been sung. The recording also sounds very clear. When he tapes him the door is closed, but the tape sounds the same throughout. Also, when his Uncle says he's gonna "slap him silly" Kevin shuts the door behind him and you can hear it shut. On the tape there is no sound of the door shutting.ShooterMcGavin34
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.jmmoosey2015
