A square-jawed, stark-countenanced actor whose features naturally projected more than a passing undercurrent of menace, David Harbour gravitated almost by default to edgy characterizations. He debuted on-camera with appearances on television series programs including Hack and Law & Order: Special Victims Unit, then transitioned to the big screen with a portrayal of Robert Kinsey, a relative of controversial sex researcher Alfred Kinsey, in Bill Condon's well-received period biopic Kinsey (2004), before signing for additional supporting roles in Steven Spielberg's War of the Worlds (2005) and Ang Lee's Brokeback Mountain (2005). In the meantime, Harbour also eked out an impressive stage career, reaching his pinnacle as Nick in the 2005 Broadway revival of Who's Afraid of Virginia Woolf? opposite Kathleen Turner, Bill Irwin, and others.
