Oona
Usually I don't watch a dramatic series on standard broadcasting, the commercials induce drowsiness - not with Hardy. Taboo is taut and suspenseful with TH ratcheting up the tension with every scene.
Oona Chaplin II is gorgeous, she has a presence about her that her mother Geraldine never had. I already knew that from Game of Thrones, she carries it well in Taboo. She and Hardy have dynamite chemistry, too bad they play siblings.
She is the granddaughter of Charlie Chaplin and the great granddaughter of Eugene O'Neil. Chaplin married Oona Sr during WW II, they stayed together until his passing. Smart man, Oona Sr was a devastating beauty!
