Though specific character details are not yet available, Tierney will play a lieutenant in the season, which premieres on NBC on Oct. 3.

Among Tierney’s best known projects is “The Affair,” the Showtime drama in which she played Helen Solloway in all five seasons from 2014 to 2019, which earned her a Golden Globe. Like “Law & Order,” her other major TV roles have been on NBC: “NewsRadio,” the ’90s sitcom in which she played Lisa Miller for all five seasons, and “ER,” the medical drama that starred her as Abby Lockhart in Seasons 6 through 15.

In film, Tierney is best known for “Primal Fear” (1996) opposite Richard Gere and Edward Norton, “Liar Liar” (1997) opposite Jim Carrey and “Primary Colors” (1998) opposite John Travolta and Emma Thompson.

More recently, Tierney recurred as Fiona McKee in the Bryan Cranston-led Showtime legal drama “Your Honor” in 2021 and played Doris Von Erich in the A24’s 2023 film “The Iron Claw.” In the Amazon Prime Video series “American Rust,” which released its second season in March, she stars as Grace Poe, and currently, she can be seen playing Cathy, mother of Kate (Daisy Edgar-Jones).
