This handsome actor began working professionally before graduating from the Actors Studio Drama School at New School University (in fact he missed commencement because he was off filming Wet Hot American Summer). Guest appearances on numerous TV series followed, but it was his supporting role on Alias that introduced his sparkling blue eyes and meticulously tousled hair to a wider audience. After leaving the drama in 2003, Cooper played Christine Lahti's much younger love interest on Jack & Bobby and finally landed his first leading role on the short-lived sitcom Kitchen Confidential. In 2006 he took a brief screen hiatus to make his Broadway debut opposite Julia Roberts in Three Days of Rain.
