21. Oona Chaplin
It was the episode that left the world silent. You can see all sorts of reactions on Youtube. “The Rains of Castamere” is, probably, the most infamous episode in TV history. Oona Chaplin’s character, Talisa, was killed during that episode. She was Robb Stark’s wife, and pregnant with their first child when she died.
Oona has gone on to star opposite some other Game of Thrones actors and Tom Hardy in FX’s new historical drama, Taboo.
