Before starring as Olenna Tyrell for The Game of Thrones, Diana Rigg has already been famous for her role in the Britsh "The Avengers", combining a strong character with a sexy appeal.
As Emma Peel, she was as brilliant as she was bad ass. She was highly skilled in martial arts and fencing, while also being a certified genius.
Her bad assery as the hottest Avenger also landed her a Bond girl role in On Her Majesty’s Service alongside George Lazenby.
At the height of her fame, she was one of the most sought after models in the world, often posing for racy and controversial photos like the one above.
She even looks shockingly similar to the foxy Natalie Dormer who played her granddaughter on Game of Thrones as well. Whoever did the casting really aced this one.
