Good stuff from Mental Floss.
Danny DeVito was originally considered for the role of Uncle Buck.
Candy appeared in more movies written or directed by John Hughes than any other actor.
Including Uncle Buck, Candy appeared in National Lampoon’s Vacation; Planes, Trains & Automobiles; The Great Outdoors; She’s Having a Baby; Home Alone; and Career Opportunities.
The film was originally supposed to take place in St. Louis.
It was changed to the Chicago area because unusually warm weather in Missouri that year forced the production to move to a more wintry climate.
If you look closely, you’ll spot a familiar face.
The classmate sitting next to Maizy in her school scene is actress Anna Chlumsky, who would later star in My Girl with Macaulay Culkin, and who can be currently seen on HBO’s Veep.
Uncle Buck is only the third theatrically released film starring Macaulay Culkin, who shot to stardom a year later thanks to his role in Home Alone—which, like Uncle Buck, was also written and produced John Hughes. The idea for Home Alone first came to Hughes while Culkin was shooting the scene in Uncle Buck where he interrogates Chanice through the mail slot. (Candy also appears in Home Alone, but he and Culkin don’t have any scenes together.)
You can visit the Russells’ house—and Buck’s apartment.
The exteriors of the Russells’ house were shot on location at 2602 Lincoln Street in Evanston, Illinois. Buck’s apartment, across the street from Wrigley Field, is located at 3708 N. Sheffield Avenue in Chicago.
You might recognize the high school from other John Hughes films.
The high school scenes were shot at New Trier West High School in Winnetka, Illinois, which wasn’t a functioning school at the time of filming. The location was also used in other Hughes films like Ferris Bueller’s Day Off and Sixteen Candles
Uncle Buck’s theme might sound familiar.
It’s a beat from rapper Tone Lōc’s “Wild Thing.”
It ran from 1990-1991 and was created without the input of John Hughes or any of the film’s cast. In fact, Hughes didn’t even know the show existed until its producers asked to use exterior footage the director shot for the movie.
There was an Indian Uncle Buck remake.
Uncle Bun was released in 1991.
You can make Buck’s huge pancakes.
But you’ll need a pretty big mixing bowl. A chef estimated that you’d need 300g of plain flour, 200g of caster sugar, 450ml of milk, 9 medium free range eggs, 100g of melted unsalted butter, and 15g of vegetable oil to make the stack of gigantic pancakes that Buck makes Miles for his birthday.
