Sam Waterston
 (Executive Assistant District Attorney Jack McCoy)

Jack McCoy grew up in the Midwest and moved to New York to attend New York University Law School. A charismatic and tough attorney who possesses great oratory skill and knowledge of the law, McCoy treats the cases he prosecutes like a gigantic chess game. Although he appears to be all work and no play, in the past he has had several affairs with assistants, one of whom he married and had a daughter with before they divorced. Outside of the courtroom, he spends his time on his Harley.

Since joining the cast of Law & Order in 1994, Waterston's role as the complex and charismatic Assistant D.A. Jack McCoy won him nominations as television's Best Dramatic Actor from the Emmys, The Golden Globes, and the Screen Actors Guild Awards -- the latter of which he won in 1999. Waterston's performances in film and television have earned him an Academy Award nomination for Best Actor for his performance in The Killing Fields, three Emmy nominations and a Golden Globe Award for the NBC series I'll Fly Away, and two Golden Globe nominations for The Great Gatsby. In addition, Waterston received a 1994 Tony Award nomination for his portrayal of the 16th President in Abe Lincoln in Illinois at the Lincoln Center Theater. Waterston's film credits include Hopscotch, Man in the Moon, The Shadow Conspiracy, John Waters' Serial Mom, Tennessee Williams' The Glass Menagerie and the Woody Allen films September, Interiors, Hannah and Her Sisters and Crimes and Misdemeanors.
