9. Olenna Tyrell While certainly "veteran presence," as we mentioned above, you don't survive in this world without being smart and tough, so her lengthy tenure at the heart of court politics testifies to both, as does her nickname, the 'Queen of Thorns.' In many way, she's the real head of House Tyrell, despite marrying into it, rather than through birth. Besides, we couldn't omit any character played by Diana Rigg, who was not just the only Mrs. James Bond (in O.H.M.S.S.), but one of the all-time GWG icons, Emma Peel.
