Kieran Culkin
With the last name as recognizable as that, it shouldn’t as a surprise to learn that Kieran Culkin is the brother of child actor Macauley Culkin. The pair both appeared together in Home Alone and its sequel, where Kieran played Kevin’s brother, Fuller. Now that’s what I call some smart casting!
In the 2000s, Kieran appeared in numerous other classic movies, like She’s All That, Igby Goes Down, and Scott Pilgrim vs. the World. However, perhaps his most iconic role is in the TV show Succession, where he plays one of the lead characters, Roman Roy. Perhaps we’ll see Macauley make a cameo on this show, too!
