'Law & Order': All the Cast Members and Familiar Faces That Have Returned So Far

The crime procedural is back with season 21, and so are several original cast members from the first 20 seasons.

With Law & Order back on the air, showrunner Rick Eid has promised that season 21 of the revival will feature many familiar faces in addition to returning stars Anthony Anderson and Sam Waterston, who are reprising their respective roles as Det. Kevin Bernard and DA Jack McCoy. “There’s so many great actors who have been involved in the show, and the opportunity for them to come back in some capacity is really exciting,” he teased. “So, I think we definitely want to find ways to bring back several of our alumni.”

Ahead of season 21’s premiere, the new cast members couldn’t contain their excitement. “There’s gonna be a lot of surprises and a lot of recurring guest stars that people have kind of grown to love in the last two decades,” said Jeffrey Donovan, who joins the series as Det. Frank Cosgrove. 

Meanwhile, Camryn Manheim, who made brief appearances in earlier seasons before joining full time as Lt. Kate Dixon, said, “I have been surprised and excited already several times. And I think the viewers will be, too.” Odelya Halevi, who plays ADA Samantha Maroun, echoed her co-star’s sentiment. “We have guest stars that I would only dream about working with,” she said, teasing that some of them are “mind-blowing.” 

Looking ahead,“I’m sure next season we’ll think about some of our alumni and how to bring them back and build an episode around someone,” showrunner Rick Eid said, revealing that he’s “heard from a few people who have indicated they’d love to come back.” 

He added, “It’s a great situation to be in. There are so many people that have been on the show and played great characters, whether they were series regulars, a judge or a defense lawyer.” 

That said, here’s a list of all the familiar faces and returning cast members that appeared on Law & Order season 21. 


Original Stars

Anthony Anderson as Det. Kevin Bernard 
Appearance: Series Regular, Season 21

NBC

Bernard first appeared on Law & Order in season 18 as a junior detective, while longtime detective, Ed Green (Jesse L. Martin), is being investigated for a shooting. Even though Green is cleared, he leaves the precinct, making way for Bernard to replace him as Det. Cyrus Lupo’s (Jeremy Sisto) new partner. 

Det. Bernard went on to appear in every episode of the two remaining seasons of Law & Order’s original run, with season 20 giving viewers a deeper glimpse into his personal and family life. As of season 21, the senior detective is now partnered with Det. Frank Cosgrove (Donovan). 

Sam Waterston as DA Jack McCoy
Appearance: Series Regular, Season 21

NBC

First introduced as an Executive Assistant District Attorney in season 5, McCoy has gone on to appear in every season of the long-running criminal procedural since. After season 17, McCoy was named the interim District Attorney, following the departure of Arthur Branch (the late Fred Thompson). 

Later, when he appeared in a crossover episode with SVU, he was referred to as District Attorney even though he later had to campaign for the position after a year and a half in the interim position. During that time, McCoy had a testy relationship with Governor Donald Shalvoy (Tom Everett Scott), who was involved with a prostitution ring. 

As of season 21, McCoy is still New York City’s DA and mentoring ADAs Samantha Maroun (Halevi) and Nolan Price (Hugh Dancy). 


Returning Cast Members 

Carey Lowell as ADA Jamie Ross
Appearance: Episode 1, “The Right Thing” 

NBC

In the season 21 premiere, “there’s a very famous actor that you’ll notice right away,” Donovan teased. And that person turned out to be Lowell, who reprised her role as Jamie Ross, an ADA whose personal and professional life overlap when she gets drawn into a messy custody battle with her ex-husband over their daughter. The character first appeared in season 7 and lasted for only two seasons before briefly appearing on the short-lived spinoff Law & Order: Trial by Jury where she had been promoted to a trial judge. 

In her latest appearance on Law & Order, it’s revealed that Ross has rejoined the DA’s office and that she helped prosecute a popular singer named Henry King for rape. After he’s released and murdered by one of his victims, Ross is briefly considered a suspect before it’s discovered she may have potentially assisted in the crime. When forced to testify, she evokes the Fifth Amendment.  

Dylan Baker as Sanford Rems
Appearance: Episode 5, “Free Speech”

NBC

After making his first appearance on Law & Order as Sean Hyland in 1991, Baker scored a recurring role as defense attorney Sanford Rems. The private practice lawyer went on to defend the likes of Carrie Salter, Qatar Khaleel and Eric Lund between seasons 14 and 16. On season 21, Rems is brought in after a congressional candidate is murdered. Although they find the killer, the case is complicated by the fact that a talk show host is accused of saying something that incited the crime. 

“Without naming names, you see this talk show host saying anything he wants and then he gets brought up in an investigation,” Donovan said of the episode, before getting excited about his off-screen reunion with Baker, who also appeared on Burn Notice as a former spy and handler of Donovan’s character Michael Westen. Although the two didn’t share any scenes together on screen, the actor said, “It was pretty great to see him come back.”
