Behind every great man is a woman of steel, and as the wife of cult leader Lancaster Dodd (Philip Seymour Hoffman), Adams is someone not to be trifled with. Her Peggy is no fool; she is the one who instantly feels suspicion about Freddie Quell (Joaquin Phoenix), her husband’s latest acolyte. While capable of great warmth and kindness, Peggy is ferociously protective and intelligent. In the same no-nonsense way she warns Lancaster about his wandering eye, she can cut down Freddie with a cold glare.
