Even before his critically-acclaimed performance as Robert F. Kennedy in the film Thirteen Days brought him to the attention of moviegoers, Steven Culp had already attracted a large following among television fans for his recurring role as the mysterious CIA agent Clayton Webb on the series JAG.

Steven has appeared as Webb on JAG, as House Speaker Jeff Haffley on The West Wing, as Dr. Corday's love interest, Dave Spencer, on ER, and as the stalwart Major Hayes on Star Trek: Enterprise. He also guest starred on CSI and Lyon's Den. Somehow, in the midst of this schedule, he managed to take on a leading role in the upcoming feature The Sisters, starring Maria Bello, Mary Stuart Masterson and Erica Christensen.

Culp's other feature films include The Emperor's Club, Spartan, Nurse Betty, James and the Giant Peach, Fearless and Dead Again. He made his primetime TV debut as John Hay in the Emmy-winning miniseries Gore Vidal's Lincoln, opposite Sam Waterston and Mary Tyler Moore. Since then he has appeared in numerous episodic television shows and TV movies, among them recurring roles on 24, Ally McBeal and Philly; guest-starring appearances on The Practice, Crossing Jordan, Providence, Boston Public and Chicago Hope; and roles in the movie-of-the-week, A Story to Die For with Angela Lansbury, How to Make a Monster, produced by Stan Winston, and the television movie Norma Jean and Marilyn.

Beginning his career in New York, Culp has worked with some of the best playwrights and directors in the American theater. He appeared in the premieres of Tony Kushner's Slavs (Actor's Theatre of Louisville), Terrence McNally's The Lisbon Traviata (Theatre Off-Park), A.R. Gurney, Jr.'s Sweet Sue (Williamstown Theatre Festival), Neil Simon's Actors and Actresses (Hartman Theatre), Keith Reddin's Highest Standard of Living (Playwright's Horizons) and Jonathan Tollins' If Memory Serves (Pasadena Playhouse).

He received Drama-Logue Awards for his performances in Angels in America at the American Conservatory Theatre in San Francisco and in the West Coast premiere of Nicky Silver's Raised in Captivity at South Coast Rep. He starred opposite Annette Bening in Coastal Disturbances on Broadway, and appeared with Kevin Kline in Richard III in Central Park. Culp was most recently seen on stage in ART at the South Coast Rep.
