Starring: Olenna Tyrell
Network: NBC

If you love Betty White, you'll adore Diana Rigg as the sharp-tongued Olenna Tyrell in Garden Girls. They say you can't teach an old dog new tricks, but this tough old lady knows more tricks than you know, and she's not afraid to tell you what she thinks of you either. Watch Olenna work her way to the top without ever leaving the garden this Fall on NBC.
