Jeremy Sisto joins the esteemed cast of NBC's Emmy Award-winning drama "Law & Order," as it returns for its 20th season. Sisto plays Detective Kevin Bernard's (Anthony Anderson) partner.

Filmed entirely on location in New York City, "Law & Order" is a compelling, realistic drama that looks at crime and justice from a dual perspective: the police who investigate crime and the district attorneys who prosecute the offenders. "Law & Order" is the longest-running crime series and the second longest-running drama in the history of television.

The Chicago native began his theatrical career early when he appeared onstage at the Goodman Theater in a production of Tennessee Williams' last play, "A House Not Meant to Stand," as well as Bertolt Brecht's "Galileo," opposite Brian Dennehy.

In Los Angeles, Sisto's theater credits include: Richard Greenburg's Tony Award-winning play "Take Me Out" at the Geffen Playhouse (his performance earned him a Los Angeles Drama Critics Circle Award for Featured Performance) and Sidney Kingsley's "Dead End" at the Ahmanson Theater. Sisto also recently made his Broadway debut in the play "Festen," a stage adaptation of Thomas Vintenberg's film "The Celebration."

Sisto was part of the esteemed cast of HBO's award-winning drama series "Six Feet Under," in which he played the role of Billy Chenoweth for five seasons. His other television credits include the leads in two widely viewed miniseries -- "Jesus" and "Julius Caesar."

On the feature-film side, Sisto's credits include "Thirteen," "Grand Canyon," "Clueless," "Without Limits," "White Squall," "Suicide Kings," "May," "Angel Eyes" and "Hideaway."

Sisto also starred in and co-produced the independent film "One Point O," which played in the Sundance Film Festival dramatic competition.

Sisto's recent films include the dramatic thriller, "Unknown," with Jim Caviezel; the edgy drama, "Broken," opposite Heather Graham; and the late Adrienne Shelley's "Waitress," the Sundance Film Festival hit comedy in which he stars opposite Keri Russell.
