Alongside his older brother Macaulay Culkin, actor Kieran Culkin also starred in the classic film Home Alone.
However, it wasn’t until the film’s premiere that he realized Macaulay Culkin was the main character.
In the film, which was released in theaters earlier in 1990, Kieran Culkin portrayed Kevin’s cousin Fuller McCallister.
He said in an interview with the LA Times that he was unaware of the movie’s premise or his brother’s prominent part.
The actor recounted spending a lot of time on set but being duped by Buzz’s co-star Devin Ratray into thinking the film was about him.
