Zach has been a familiar presence to audiences of television, screen and stage for decades. He can currently be seen on the acclaimed CBS series "The Good Wife" as the ethically-challenged family lawyer, David Lee. Other shows on which he played regular roles include the highly-praised “C16:FBI” on ABC and “Touching Evil" on USA Network. Zach has also recurred in a number of critically acclaimed series, including Fox's “24," in which he played the fixer Carl Webb, and HBO's “Deadwood," in which he played Andy Cramed, the gambler who brought the plague to town. He joined Bill Nighy and Christopher Walken in “Turks and Caicos,” the second installment of David Hare’s BBC thriller, “The Worricker Trilogy," coming to PBS in the Fall of 2014. His film credits extend back to the cult classics “A Shock to the System," starring Michael Caine, and Mike Figgis’s “Liebestraum." More mainstream film credits include “Tommy Boy," “Twister," and “Donnie Brasco." He has been privileged to work with some of the great film directors of our time: with David Fincher on “Fight Club” and “Zodiac," Ang Lee on “Ride with the Devil," and Clint Eastwood on “J. Edgar." He can be seen in the 2014 “Robocop," directed by José Padilha.
Between television and film engagements, Zach takes every opportunity to return to stage work. He was nominated for a Tony Award® for his portrayal of Beethoven in Moisés Kaufman’s “33 Variations” starring Jane Fonda, and most recently for a Lucille Lortel Award for his performance in John Patrick Shanley’s “Storefront Church” at the Atlantic Theater Company. His portrayal of Dick Cheney in David Hare’s “Stuff Happens” at the New York Shakespeare Festival was recognized with Ensemble Awards by both the Drama League and the Drama Desk. He has twice shared the Roundabout Theatre Company’s Broadway stage with Frank Langella, in Robert Bolt’s “A Man for All Seasons” and Terrence Rattigan’s “Man and Boy." He worked with another legendary performer, Julie Harris, in Tim Mason’s “The Fiery Furnace” at Circle Repertory Theatre. He originated the role of Dr. Chapman in David Rabe’s “A Question of Mercy” at New York Theatre Workshop, a performance that earned him an Outstanding Artist honor from the Drama League. His first Broadway credit was Larry Gelbart's "Mastergate," in which he had no lines, but played all four lawyers: Mr. Child, Mr. Picker, Mr. Boyle and Mr. Carver.
