Odd guest role.
According to a report by E!, "Grey's Anatomy" has put out a casting call for a new doctor. The character will be in his 40s and would be slated to appear on three episodes. While there's nothing strange about a doctor guest role on "GA," it's a little odd that, reportedly, we would only hear this doctor's voice and never actually see him!
