Emmy Award-winning drama series “ER,” is still one of television’s highest-rated dramas on television and NBC’s #1 drama. Created by best-selling author Michael Crichton (“Jurassic Park”), the series centers on the medical personnel in the emergency room of a Chicago hospital. Crichton is also an executive producer, along with John Wells (“China Beach”) and Christopher Chulack.

“ER” is now in its 12th season and stars Laura Innes (“Deep Impact”), Mekhi Phifer (“Clockers”), Goran Visnjic (“The Deep End”), Maura Tierney (“Insomnia”), Parminder Nagra (“Bend It Like Beckham”), Linda Cardellini (“Scooby-Doo”), Shane West (“Once and Again”) and Scott Grimes (“Mystery, Alaska”).

A winner of the prestigious George Foster Peabody Award, the series has also earned 115 nominations as well as 23 Emmy Awards including Outstanding Drama Series at the Emmy Awards in 1996. Also, the cast has won four Screen Actors Guild Awards for Outstanding Ensemble Performance in a Drama Series.

“ER” tracks the inner workings of County General Hospital, a Level One Trauma Center where heroic doctors and nurses are faced with life-and-death decisions on a daily basis. The chief of staff, Dr. Kerry Weaver (Innes), a tough and determined administrator, finds herself at a personal crossroads, trying to strike a balance between her life as a doctor and the life she now wants as a woman.

Also on staff are Dr. Luka Kovac (Visnjic), an ER attending physician from Croatia who is searching -- sometimes self-destructively -- for something to fill the void of his lost family and failed relationships; Abby Lockhart (Tierney), who recently made the professional transition from nurse to doctor, is making a serious effort to turn her personal life around; and Dr. Gregory Pratt (Phifer), a brash, fourth-year resident with a checkered background that won’t stop haunting him.

Newer additions to the ER include Neela Rasgotra (Nagra), a British-Indian medical student who arrives in Chicago after finishing her undergraduate degree in biophysics and molecular biology at Yale. Samantha Taggart (Cardellini) is a nurse and spirited single mother determined to save lives in a place where nothing is taken for granted. Dr. Ray Barnett (West) is a doctor who would sometimes rather be playing in his band than treating patients --and he has a way with the ladies and a knack for making things go smoothly, most of the time. Dr. Archie Morris (Grimes) is the new chief resident who finds that his stringent methods don’t always agree with everyone in the ER.

“ER” is a production of Constant c Productions and Amblin Television in association with Warner Bros. Television.
