Kieran Culkin in Real Life
Judging from his last name, you can probably guess that Kieran Culkin is Macaulay’s little brother. The two started their acting careers at around the same time, but Kieran was shoved to the sidelines as his older brother became a Hollywood sensation in the 1990s.
Since then, Kieran has done a lot of acting work. By a lot, we mean he’s appeared in over 20 films and nearly as many TV shows. Today, he plays the role of Roman Roy on HBO’s Succession, though we’ll mainly remember Kieran for being the man-stealing roommate of Scott Pilgrim in Scott Pilgrim vs. the World.
