A dyed-in-the-wool New Yorker, actress Rosemarie DeWitt made a steady transition from dreaming about acting to making a name for herself in the city's vibrant theater industry. Following years of increasingly larger roles on the stage and on the small screen, it was an unusual family connection that provided her first major break into feature films. As the great granddaughter of the film's subject, boxer James J. Braddock, DeWitt landed a plum role in Ron Howard's Depression-era bio, "Cinderella Man" (2005). Taking her Hollywood shot, DeWitt went on to demonstrate her mix of comedic and dramatic chops in a variety of big and small screen projects, standing out as the face-to-watch with her take on the romantically-inclined hostage negotiator Emily Lehman on the Fox series "Standoff" (2006-07), starring opposite future husband, Ron Livingston. After earning wider attention for her recurring role as Don Draper's bohemian lover on "Mad Men" (AMC, 2007- ), DeWitt earned widespread award attention for her supporting turn in "Rachel Getting Married" (2008). From there, she delivered a capable turn in "The Company Men" (2010) and spent three seasons as Toni Collette's self-absorbed sister on the critically acclaimed comedy "The United States of Tara" (Showtime, 2009-2011). By the time she garnered more praise for the indie film "Your Sister's Sister" (2012), DeWitt was well-established as a skilled actress capable of turning in quality performances in any role she chose.
