The three lookalikes turned up at the hospital after a county fair accident left a number of people injured. In addition to Eryn Rea as the Izzie double, Jackie Chung appeared as the Cristina doppelganger, and Brandon Tyler Russell appeared as the new George. It’s easy to see why the show cast these actors to kinda sorta reprise the original Grey’s Anatomy roles. There are definitely strong resemblances between the new actors and their predecessors in the forms of Katherine Heigl, Sandra Oh, and T.R. Knight. That said, there’s definitely one actor who most resembles the original. Seriously, if there’s ever a Lifetime movie made about the life and career of Katherine Heigl, Eryn Rea should get the call. Just take a look!
