Maggie Siff

With her extensive stage training, Maggie Siff projected an image of cultured sophistication that set her apart from other actresses of her generation. That sense of timeless savoir-faire would serve her well in her breakthrough role on "Mad Men" (AMC, 2007-15) playing Rachel Menken, the beautiful department store heiress with the good sense to turn down a romantic escapade with Jon Hamm's Don Draper. From that point, Siff would prove herself a reliable talent in roles that demanded a wary, almost tragic intelligence, including a still-defiant Israeli bomb survivor whose body was riddled with human shrapnel on "Nip/Tuck" (FX, 2003-2010), and Dr. Tara Knowles, the prodigal love of Charlie Hunnam's Jax Teller on "Sons of Anarchy" (FX, 2008-2012), a role for which Siff would garner audience and critical praise. In the first decade of her television and film career, in just a handful of roles, stage veteran Maggie Siff established herself as an actress capable of performances suffused with intelligence, strength, and deep reserves of world-weary charisma.
