Kieran Culkin shares why he had "no idea" what Home Alone was about while filming

Kieran Culkin didn’t understand Home Alone’s plot while filming, despite his role alongside brother Macaulay.

Kieran Culkin, who played Kevin McAllister's cousin Fuller in the 1990 holiday classic Home Alone, recently revealed he didn’t fully grasp the movie’s storyline during production. In an interview with the Los Angeles Times while promoting his new film A Real Pain with director and co-star Jesse Eisenberg, Culkin shared his amusing experience as a child actor on the iconic set.

“I had no idea what that movie was about when I saw it, and I was in it,” said Culkin, now 42. Reflecting on the premiere, he added, “I was dying laughing. It was the funniest thing I had ever seen. I had no idea what the movie was about.”

Culkin explained that his involvement in Home Alone as a young child was straightforward: “Drink this Coke, wear the glasses, say the thing that you memorized, look cute and go home.” He also recalled a humorous moment when his co-star Devin Ratray, who played Buzz, jokingly told him the movie was all about Buzz’s character, which Culkin believed at the time.

While his brother Macaulay Culkin gained international fame for his lead role as Kevin McAllister, Kieran admitted he only realized the true plot of the movie after seeing it at the premiere.

Culkin shared his reflections while promoting A Real Pain, a comedy-drama where he and Eisenberg play cousins traveling to Poland after their grandmother’s death. The two bonded over their shared Home Alone memories, with Eisenberg admitting he watched the movie 17 times in theaters.

Despite not understanding the film’s storyline at the time, Culkin fondly recalls growing up watching Home Alone each Christmas, cementing its place as a holiday favorite for fans worldwide.
