Dr. George O’Malley
Dr. George O’Malley was part of the original batch of interns that started on the first season of “Grey’s Anatomy.” We watched a nervous and unsure O’Malley transform into a confident surgeon with calm fingers. Although reports surfaced that T.R. Knight, the actor who portrayed O’Malley, was leaving the show after five seasons to pursue a career on Broadway, fans were still heartbroken to learn the unidentified patient that stepped in front of a bus to save a stranger was actually O’Malley. Sadly, he died from his injuries shortly after his co-workers realized who the unidentified hero really was.
