Some celeb siblings have taken on Hollywood together. There's Elle and Dakota Fanning, who seem to take turns playing precocious teens and twentysomethings. Owen and Luke Wilson are in the habit of signing on for the same films. And a debate about whether Liam or Chris Hemsworth is the bigger movie star might cause some friendships to end, but won't get you any closer to an answer.
But what about the celeb siblings that have largely stayed out of the limelight? The less-famous family members still appear in the larger pop culture landscape from time to time. Sometimes, it's in a birthday shoutout from their more-famous sibling. Sometimes, they even get to accompany their bro or sis to a red-carpet event. Take our quiz and see how good you are at spotting a family resemblance.
