2. Brian George: Then
As the father of Raj and his sister Priya, Dr. V.M. Koothrappali is an interesting character on the show. Audiences mostly see the face of Brian George on a computer screen in early episodes. For years he’s only “on screen” time is when Raj video chats with him. After he and Raj’s mother divorce, the doctor finally flies to the United States to visit his children.
