Zach Braff (Then)
John “J.D” Dorian, played by Zach Braff, blissfully narrated many of the show’s episodes which followed the character’s struggles to navigate through the tough world of medicine while developing ever-evolving relationships with his coworkers. Before his debut on “Scrubs,” Braff had previously played Andrew Largeman in “Garden State,” voiced the title character in “Chicken Little” and made appearances on “Arrested Development.”
