Do You Recognize These Celeb Siblings?

Kieran Culkin 1 of 11

Look at that face. Doesn't he look familiar? Oh, that's right! He played Wallace in 'Scott Pilgrim vs. the World.' That must be it! Or could he have been in something else? Ooh! Yes! He was Simon in 'She's All That,' too! I've probably seen him in something else, too, haven't I?

Ding ding ding! That face belongs to Kieran Culkin, Macaulay Culkin's younger brother. And I'm going to assume that you've probably seen him in something other than 'Scott Pilgrim' and 'She's All That.' But why? Why would I so confidently make this assumtion about you?

He played Fuller in 'Home Alone.'
