Throughout his decades-long career, intense character actor Terry O'Quinn made his mark playing men of determination - everything from law officers and military men to captains of business. Following his film debut in "Heaven's Gate" (1980), O'Quinn moved back and forth with ease between film and television, landing roles in TV movies like "Right to Kill?" (ABC, 1985) and "R vs. Wade" (NBC, 1989), while appearing in features like Stephen King's "Silver Bullet" (1985) and "Young Guns" (1988). He achieved cult popularity with "The Stepfather" (1987) and "The Stepfather 2" (1989), playing a sociopathic killer who murders his family. O'Quinn had noted supporting roles in studio films as well, playing Howard Hughes in "The Rocketeer" (1991) and Mayor Clum in "Tombstone" (1993) before landing a regular role as a mysterious ex-FBI agent on the mystery drama series, "Millennium" (Fox, 1996-99). But after a recurring role as FBI Director Kendall on "Alias" (ABC, 2001-06), O'Quinn became a favorite of series creator J.J. Abrams, who asked the actor to join the ensemble cast of the mystery sci-fi hit, "Lost" (ABC, 2004-2010). For six seasons, the actor captivated viewers as the faith-based Locke, who routinely butted heads with his other castaways while earning his place among fans as one of the most intriguing and popular characters on the series. At long last, O'Quinn had risen from a relatively unknown supporting player to a major Emmy Award-winning star.
