Daughter of the refined, Oscar-nominated American actor Sam Waterston (The Killing Fields, Law & Order), statuesque actress Katherine Waterston attended New York University and then followed her dad's footsteps by entering the arena of acting, taking her on-camera bow in fellow show-business scion Bryce Dallas Howard's short-subject film Orchids. Waterston scored her featur- film debut with a bit part in Tony Gilroy's Best Picture-nominated Michael Clayton (2007) and signed for her first lead in a Hollywood feature in David Ross' black comedy The Babysitters (2007), in which she played an honors student who slides into an affair with a dissatisfied suburban househusband and then turns the tables to engage in a little fly-by-night prostitution (and collect some college money in the process) via affairs with the husband's friends. At about the same time, Waterston signed on for the John Cusack thriller The Factory (2009). ~ Nathan Southern, All Movie Guide
