Law & Order Alum Sam Waterston To Reprise Role In SVU Season 19

Jack is finally back. 

Variety reports that Law & Order alum Sam Waterston, who starred on the series for 16 seasons, is set to reprise his role as prosecutor Jack McCoy on Law & Order SVU. 

Waterston will make a guest appearance on an upcoming episode of the NBC spinoff series' 19th season, which will debut on September 27. The role reunites him with new SVU showrunner Michael Chernuchin, who worked with Waterston during the actor's first two seasons on the show. Chernuchin also had a hand in creating the character of Jack McCoy. 

No additional details on Waterston's involvement on the upcoming season were given, but we'll update you when we learn more. 

Waterston first joined the legal drama in its fifth season, staying through to its 20th. That season became its last when NBC abruptly canceled the series in 2010, just one season shy of breaking Gunsmoke's record for longest-running primetime drama in history. 

Chernuchin, Dick Wolf, Mariska Hargitay, Julie Martin, Arthur W. Forney, and Peter Jankowski executive produce the series, which stars Hargitay as Lieutenant Olivia Benson, Peter Scanavino as Detective Dominick "Sonny" Carisi, Jr., Kelli Giddish as Detective Amanda Rollins, Ice-T as Sergeant Odafin "Fin" Tutuola, and Raúl Esparza as A.D.A. Rafael Barba.

Waterston currently stars on the Netflix series Grace and Frankie, alongside Jane Fonda, Lily Tomlin, and Martin Sheen.

Law & Order: SVU season 19 is slated to premiere later this month, but the air date for Waterston's episode in particular hasn't been set as of yet. For now, check out the untold truth of Law & Order: SVU.
