Robin Weigert is best known for her role as Calamity Jane in the HBO series Deadwood, for which she received a 2004 Emmy Award nomination for Best Supporting Actress in a Drama Series.  She appeared previously on HBO as the Mormon Mother in Mike Nichols' Golden Globe-winning Angels in America, starring Meryl Streep, Al Pacino and Emma Thompson.  Recent film credits include Steven Soderbergh's The Good German, starring George Clooney and Cate Blanchett, Things We Lost in the Fire, starring Benicio del Toro and Halle Berry, and Winged Creatures, starring Forrest Whitaker, Kate Beckensale and Dakota Fanning.  Upcoming films include Charley Kaufman's Synecdoche New York starring Philip Seymour Hoffman and Rebecca Miller's The Private Lives of Pippa Lee starring Robin Wright Penn, Maggie Gyllenhal and Alan Arkin.  Robin was a regular for a season of Life on NBC, and has recurred on Lost and Cold Case.  

Before moving to Los Angeles, Robin enjoyed an almost decade long stage career in New York.  Most recently on Broadway as Poppy Norton-Taylor in the hit revival Noises Off, she was nominated for Drama Desk and Lucille Lortel awards for her acclaimed turn in Richard Nelson's Madame Melville.  Mike Nichols invited her to share the role of Masha with Marcia Gay Harden in his Central Park production of The Seagull, with a cast that included Meryl Streep, Kevin Kline, Natalie Portman, Phillip Seymour Hoffman and Christopher Walken, an experience she still considers one of the highlights of her stage career, even though she only got to perform the role twice.  Other stage credits included Twelfth Night (Lincoln Center), A place at the Table (MCC), Arms and the Man (Roundabout), Hamlet (Public), Goodnight Children Everywhere (Playwright's Horizons) and Pride's Crossing (Lincoln Center).  She's also appeared regionally at McCarter, Arena Stage, Long Wharf, New York Stage and Film, A.C.T. and the Berkshire Theater Festival.  It gave her great pleasure to return to A.C.T. between seasons two and three of Deadwood to play the role of Josie in O'Neil's A Moon for the Misbegotten, for which she received a Theatre Critics Circle Award.

Robin received her MFA in acting from NYU.
