Mary McCormack is one of today’s boldest and most versatile actresses, continually challenging herself with roles that often defy Hollywood standards and bring to light the complex lives of ordinary women. She has shown her immense talent working in film, television and on stage and has tackled roles ranging from slapstick comedy to intense drama.
Perhaps best known for her five-season tenure on USA Network’s hit original series “In Plain Sight” and her role as the Deputy National Security Advisor, Kate Harp, in Aaron Sorkin’s NBC smash hit “The West Wing,” McCormack has also starred in the NBC comedy series “Welcome to the Family,” alongside Mike O’Malley. McCormack recently completed production on “The Compound,” an independent feature film that follows two star-crossed teens on a polygamist compound who fight their families’ religious tradition to be together. McCormack will soon be seen in Aram Rappaport's “A Conspiracy on Jekyll Island,” opposite Dianna Agron, AnnaSophia Robb, Ed Westwick, Minnie Driver, Maggie Q, Frank Grillo and Christopher McDonald. She can also be seen opposite Imogen Poots in the Terrance Malick-produced independent film “A Country Called Home.” McCormack has also appeared on the ABC series “Scandal,” HBO's “The Newsroom,” and Showtime's “House of Lies.” She currently can be seen guest starring in “Angie Tribeca” on TBS and in Gus Van Sant’s new drama mini-series “When We Rise” with Guy Pearce and Mary-Louise Parker.
McCormack returned to the Broadway stage in 2008 to star in “Boeing-Boeing” alongside Christine Baranski, Mark Rylance and Bradley Whitford. Marc Camoletti’s classic 60s comedy earned McCormack a 2008 Tony nomination for “Best Performance by a Featured Actress in a Play.” Additional stage credits include a highly successful run opposite Alan Cumming as Sally Bowles in the Sam Mendes and Rob Marshall-directed Broadway production of “Cabaret” for the Roundabout Theatre Company; the acclaimed London stage production of Neil LaBute’s play “Bash”; the David Warren-directed productions of “My Marriage to Earnest Borgnine; and “A Fair Country.”
