10. Amy Adams
As Lancaster Dodd's quietly manipulative wife, Amy Adams is the secret, beating heart of The Master. Anderson's film is driven by the weird dynamic between Dodd (Philip Seymour Hoffman) and his protégé Freddie Quell (Joaquin Phoenix) – the former is confident, cuddly, and always has an answer for everything, while the latter is angry, angular, and always lost. But Adams' character discreetly fuels these contrasts, and towards the end, we wonder if she might have been the behind-the-scenes power behind Dodd after all. A subtle character likes that requires a very subtle performer, and Adams transfixes in the role.
