Writer David Ives talks about his prolific and wide-ranging playwrighting career, including his new comedy at the Classic Stage Company, The Liar, loosely adapted from Le Menteur by Pierre Corneille. He also talks about his current collaboration with Stephen Sondheim on a yet-to-be-titled new musical, based on film director Luis Bunuel's The Discreet Charm of the Bourgeoisie and The Exterminating Angel, scheduled for The Public Theater's 2017-2018 season.
