Nathan Fillion & Jason Bateman

We think actors Nathan Fillion and Jason Bateman look like they could be brothers. Fillion’s detective show, Castle, has even used their resemblance as a running gag.

Julian Lennon / Ari Gross

Here at Pop-A-Looza HQ, we’ve always thought that musician Julian Lennon and actor Ari Gross, look as if they might share some common DNA. We even dug up these two pics from the 80’s, in which the duo are wearing very similar earrings!

Millie Bobby Brown / Natalie Portman

Here at Pop-A-Looza HQ, we’re in agreement that Millie Bobby Brown and Natalie Portman look like they could be close relatives!

Katina & Samantha

Here at Pop-A-Looza HQ, we’re struck by how much YouTube star Katina (Katina Eats Kilos) looks like travel maven, Samantha Brown. We think the two could pass for sisters!

Adam Hastings & John Lennon

There’s nothing we like better here at Pop-A-Looza HQ, than a good Beatle look-a-like, and we think we’ve spotted the BEST. You’d be forgiven if you couldn’t pick out the real John Lennon from cast member of The Fab Four, Adam Hastings. The resemblance is nothing short of amazing. That’s Adam on the left!

Double Take!

While actors Rashida Jones and Zooey Deschanel would probably never be mistaken as the same person, they do occasionally look sisterly-similar.
