Home Alone succeeded because the heavy doses of schmaltz and whimsy necessary for a family film were balanced out by the slapstick violence. Macaulay Culkin’s Kevin McCallister doesn’t come of age or really learn much besides how to aim paint cans at the heads of the two burglars trying to break into his house—but he does have to take on grownup responsibilities until his parents get back. While he gets to set up a number of elaborate booby-traps throughout his house, he also has to buy groceries and cook for himself. After all that, it seemed like Kevin could just return to his old life. But the man who created him found it harder to do the same after Home Alone’s massive success.

After the success of Home Alone, Hughes’s movies noticeably changed their focus to appeal to a broader audience. They grew more polished, but missed the originality and distinct appeal of his earlier works. Home Alone signified a change of direction for Hughes, and a shift in focus away from the fertile terrain he’d explored in his earlier films. While the McCallisters live in the Chicago suburbs where nearly every other Hughes film is set, the conceit is notably different from the more formulaic films of the 1980s (starting with 1984’s Sixteen Candles and continuing through 1989’s Uncle Buck).

Hughes himself said that he envisioned his characters all living in the same universe, the fictional town of Shermer, Illinois (based largely on the Chicago suburb of Northbrook where Hughes lived as a teenager). But the world of Home Alone doesn’t bear any resemblance to the Shermer of his other films; it was filmed and takes place in the real village of Winnetka along Lake Michigan. In many ways, it’s Hughes leaving Shermer behind.

The triumph of the first Home Alone movie marked the end of Hughes’s great run, one that included three National Lampoon’s Vacation films starring Chevy Chase and Beverly D’Angelo, the teen movies, and Planes, Trains, and Automobiles. Those films, untouchable by many standards, helped redefine comedy, but they didn’t make nearly as much money as Home Alone did. For a comparison, Ferris Bueller’s Day Off, one of Hughes’s most successful films both financially and critically, made an admirable $70,136,369 when it was released in 1986. Home Alone had a final gross of $285,761,243 just four years later.

Financially speaking, it probably would have been difficult for Hughes to go back to making those kinds of films, the ones with curse words and teenagers realizing they were on the terrifying cusp of adulthood. A scathing 1992 article by Richard Lallch for Spy magazine took a behind-the-scenes look at what it was like working in “Hughesland” just two years after Home Alone came out. The piece portrayed Hughes as a “crazed, scary, capricious bully” who was “getting at least $10 million a year to crank out consistently mediocre money losers.” Hughes Entertainment wasn’t the seemingly fun and loose hangout that you imagined his earlier films coming from, but after a string of failures all released in 1991—Career Opportunities, Only the Lonely, Dutch, and Curly Sue—Lallch surmised that Hughes “badly” needed a hit. The result? Home Alone 2, which netted $173 million in the U.S. alone.
