Phylicia Rashad is returning to TV. The "Cosby Show" star has signed on to appear in NBC's "Do No Harm," according to TV Guide. In the show -- a modern day take on Dr. Jekyll and Mr. Hyde -- Rashad will play Dr. Vanessa Young, the chief of surgery and boss to the show's main character Dr. Jeffrey Kohl.
