The O.C. first graced our television screens in August 2003, and it was a fan-favorite until it left the air in 2007. In the almost ten years since the show ended, the cast has been keeping busy — and, yes, some of the actors and actresses look totally different.

Ben McKenzie welcomed his first child, and so have his co-stars Adam Brody and Rachel Bilson. It’s no surprise, especially because it’s been ten years, but it’s still amazing to see photos from The O.C. days next to their current pics. With the anniversary of the finale coming up in February, it’s no better time to see how much Ryan Atwood and Seth Cohen have transformed since then. We’ll always hold a special place in our hearts for the Newport Beach crew.

Watch the video above to see what the cast looks like now, then click through the gallery to see photos of the cast then-and-now. Did any of these surprise you? Let us know in the comments below which transformation shocked you the most!
