Home Alone is one of the most beloved Christmas movies of all time, and it's easy to understand why. Directed by Chris Columbus and written by the late, great John Hughes, it has comedy, action, tension, and above all else, heart.
In case you're one of the three people who hasn't seen it before, the movie stars a young Macauley Culkin as Kevin McAllister, the youngest kid in a dysfunctional family who are about to leave on a trip for Christmas. A power outage forces the family to rush to the airport, only to realize once they're in the air that they've forgotten Kevin, who is now, as the title says, home alone.
Meanwhile, Kevin now has to protect his house from the Wet Bandits, a pair of criminals who are systematically breaking into each house in the neighborhood and robbing them. Between his quick-thinking and the help of a misunderstood neighbor, Kevin is able to keep them away until they're caught by the police, at which point his family makes it back home.
It's a great premise, but it's one that leaves a lot of people with one particular question; how the hell does his family not notice he's missing until they're already on the plane? Turns out there's an answer that a lot of people tend to miss.
