Macaulay improvised the 'Home Alone' bathroom expression

The festive flick’s director Chris Columbus admitted that the “iconic” hands on the face move by Macaulay during the bathroom routine was a total “accident” after the child star didn’t follow his notes.

The 65-year-old filmmaker told Insider for the film’s 30th anniversary: "If you put something on your face that burns, most people move their hands right away. So my direction to him was when you pat your face, move your hands and scream. And I think it was the first take, he kept his hands on his cheeks

"It's funny, the iconic moment from 'Home Alone' was an accident."
