This D.A. just struck a new deal.
"Very few casting announcements have ever given me this much pleasure," the executive producer said in a statement. "Since day one, Sam has had perfect pitch when it comes to Jack McCoy as a character who both reflects and expands our ability to understand the law. He is the ultimate conscience of the show and I look forward to him emulating the career of New York District Attorney Robert Morgenthau, who served until he was 90."
Wolf, the producer behind spinoffs Law & Order: Special Victims Unit and Law & Order: Organized Crime, previously gushed that the revival—marking a 21st season for the beloved series—is "literally dreams come true."
Per the original announcement, the new Law & Order will pick up where the drama left off in 2010, offering an even closer look at "the police who investigate crime and the district attorneys who prosecute the offenders."
NBC is also ushering in a new spin-off Law & Order: For the Defense next season.
Waterston previously joined Law & Order in 1994 during its fifth season. He also made a brief guest cameo as McCoy in spin-off SVU in 2017.
Law & Order season 21 premieres Thursday, Feb. 24 at 8 p.m. on NBC.
