Development The idea for
Law & Order: Special Victims Unit originated with the 1986 "preppie murder" case of
Robert Chambers, who strangled and killed a woman he dated, Jennifer Levin, during
what he claimed was consensual "rough sex" in
Manhattan's
Central Park. The crime inspired
Dick Wolf to write the story for the
season one episode of
Law & Order titled "
Kiss the Girls and Make Them Die". After writing the episode, Wolf wanted to go deeper into the psychology of crimes to examine the role of
human sexuality. The original title of the show was
Sex Crimes. Initially, there was concern among the producers that, should
Sex Crimes fail, identifying the new show with the
Law & Order franchise could affect the original show. Additionally,
Ted Kotcheff wanted to create a new series that was not dependent upon the original series for success. Wolf felt, however, that it was important and commercially desirable to have "Law & Order" in the title, and he initially proposed the title of the show be
Law & Order: Sex Crimes.
Barry Diller, then head of
Studios USA, was concerned about the title, however, and it was changed to
Law & Order: Special Victims Unit to reflect the actual unit of the
New York City Police Department (NYPD) that handles sexually based offenses. Executive producer
Neal Baer left
Law & Order: SVU as
showrunner at the end of
season twelve, after eleven years (seasons 2–12) on the show, in order to sign a three-year deal with
CBS Television Studios. Baer was replaced by former
Law & Order: Criminal Intent showrunner
Warren Leight. In March 2015, it was announced that Warren Leight signed a three-year deal with
Sony Pictures Television, that will allow him to work on
SVU one more season, its seventeenth. It was announced on March 10, 2016, that original
Law & Order veteran producer Rick Eid would take Leight's place as showrunner starting in season 18. Creator Dick Wolf commented to
The Hollywood Reporter, "I'm extremely pleased that Rick had decided to rejoin the family and hope that he will be here for years to come." During post-production of season 18, following the announcement that
SVU was renewed for a nineteenth season, it was revealed that Rick Eid departed the series. He will be taking over another Dick Wolf/NBC series,
Chicago P.D. It was announced on May 25, 2017, that original
Law & Order and
Law & Order: Criminal Intent showrunner
Michael S. Chernuchin would be reprising his role starting on season nineteen. Chernuchin was also co-creator and executive producing showrunner of
Chicago Justice, another Wolf-related show that was canceled by NBC at the end of the 2016–17 TV season. On April 22, 2019, it was announced that Leight would return as showrunner for the series' twenty-first season. On May 3, 2022, Leight announced that he would not be returning for the twenty-fourth season. In May 2025, NBC renewed the series for its twenty-seventh season; Michele Fazekas assumed the role of showrunner, becoming the first woman to serve in the position for
Special Victims Unit. In April 2026, NBC renewed the series for its twenty-eighth season. Fazekas is expected to return as showrunner for this season as well.
Casting ,
Christopher Meloni and
Ice-T during filming of the 12th season Casting for the lead characters of
Law & Order: Special Victims Unit occurred in the spring of 1999. Dick Wolf, along with officials from NBC and Studios USA were at the final auditions for the two leads at
Rockefeller Center. The last round had been narrowed down to seven finalists. For the female lead, Detective
Olivia Benson, actresses
Samantha Mathis,
Reiko Aylesworth, and
Mariska Hargitay were being considered. For the male role, Detective
Elliot Stabler, the finalists were
Tim Matheson,
John Slattery,
Nick Chinlund, and
Christopher Meloni. Hargitay and Meloni had auditioned in the final round together and, after the actors left, there was a moment of dead silence, after which Wolf blurted out, "Oh well. There's no doubt whom we should choose—Hargitay and Meloni." Wolf believed the duo had the perfect chemistry together from the first time he saw them together, and they ended up being his first choice.
Garth Ancier, then head of NBC Entertainment, agreed, and the rest of the panel assembled began voicing their assent. The first actor to be cast for the show was
Dann Florek. Florek had originated the character of Captain
Don Cragen in the 1990 pilot for
Law & Order, and played the character for the show's first three seasons until he was fired on the orders of network executives, who wanted to add female characters to the all-male primary cast, but he maintained a friendly relationship with Wolf, and went on to direct three episodes of the original series as well as to occasionally guest star on the show. Shortly after Florek reprised his role for
Exiled: A Law & Order Movie, he received a call to be on
Sex Crimes. Initially reluctant, he eventually agreed to star on the show as Cragen on the assurance that he would not be asked to audition for the role. Shortly after the cancellation of
Homicide: Life on the Street,
Richard Belzer heard that
Benjamin Bratt had left
Law & Order. Belzer requested his manager to call Wolf and pitch the idea for Belzer's character from
Homicide, Detective
John Munch, to become the new partner of
Jerry Orbach's character, Detective
Lennie Briscoe, since they had previously teamed in three
Homicide crossovers. Wolf loved the idea, but had already cast
Jesse L. Martin as Briscoe's new partner, Detective
Ed Green. The idea was reconfigured, but to have Munch on
Law & Order: Special Victims Unit instead.
Dean Winters was cast as Munch's partner,
Brian Cassidy, at the insistence of Belzer. Belzer looked at Winters as a sort of little brother, and told Wolf, "Well, I'll do this new show of yours,
SVU, only if you make Dean Winters my partner." He subsequently became a recurring character into season 15. The void left by Winters's departure was filled for the remainder of the season by
Michelle Hurd as Detective
Monique Jeffries, a character who Wolf promised that, despite starting out as a minor character with one scene in the pilot, would eventually develop. Hurd left the show at the beginning of season two to join the cast of
Leap Years. Munch's permanent partner came in the form of
rapper-turned-actor
Ice-T, who had previously worked with Wolf on
New York Undercover and
Exiled. Ice-T originally agreed to do only four episodes of
Law & Order: Special Victims Unit, but he quickly gained affection for the ensemble nature of the cast. He relocated to New York City before his four-episode contract was up and remained with the show as Munch's permanent partner, Detective
Odafin "Fin" Tutuola. Initially, the show focused exclusively on the police work of the detectives in the Special Victims Unit of the 16th precinct, with members of the District Attorney's office occasionally appearing as guest roles crossing over from the original
Law & Order. From season two onwards, the format was changed to be more faithful to the original
Law & Order concept by including court cases.
Stephanie March had little television experience before being cast on
Law & Order: Special Victims Unit, nor did she watch much TV. Nevertheless, March was cast as Assistant District Attorney
Alexandra Cabot at the beginning of season two but still believed that, due to the grim nature of the series, it would be short-lived. She stayed with the series for three seasons, however, and left when she believed she had reached the natural conclusion of the character's development. She would later reprise the character as a guest appearance in season six and as a regular character on the short-lived Wolf series,
Conviction, where she was promised more to do.
Diane Neal had previously guest-starred on
Law & Order: Special Victims Unit in season three before being cast as Cabot's replacement,
Casey Novak, in season five. Neal remained with the show through the end of season nine, after which she was replaced by
Michaela McManus. March returned to the show in the tenth season (after McManus' departure from the cast) when
Neal Baer proposed Cabot receive a character arc to revitalize the second part of the season, which would continue through season eleven.
Tamara Tunie was cast as
medical examiner Melinda Warner in season two after working with Wolf previously on
New York Undercover,
Feds, and
Law & Order. Warner was initially a
recurring character but became a regular character in season seven, and Tunie was added to the opening credits at that time. When initially cast as Warner, Tunie was appearing as attorney Jessica Griffin on the
CBS daytime soap opera
As the World Turns. From 2000 to 2007 (and again briefly in 2009), she appeared on both series simultaneously. In 2002, she also appeared on the
Fox espionage-themed drama series
24, in the recurring role of CTU Acting Director Alberta Green.
BD Wong was asked to film four episodes as Dr.
George Huang, a
Federal Bureau of Investigation (FBI)
forensic psychiatrist and
criminal profiler on loan to the Special Victims Unit. After his four episodes, he was asked to stay on with the show. After he starred in
Bury My Heart at Wounded Knee and guest-starred as Detective
Chester Lake in the eighth season, Wolf felt that
Adam Beach would be a good addition to the cast and asked him to be a permanent member beginning with the ninth season. Although Beach felt the role was a "dream role", the character proved unpopular with fans who felt that he was designed to gradually write out either Richard Belzer or Ice-T. Feeling there were too many police characters on the show, Beach left the show after only one season.
Michaela McManus was originally felt to be too young for the role of an
Assistant District Attorney (ADA) before being cast as ADA
Kim Greylek in the tenth season. McManus, months removed from a recurring role on
One Tree Hill, remained with the series only half a season, however, before departing for unspecified reasons.
Paula Patton joined the cast as
ADA Mikka Von. She replaced
Stephanie March. However, Patton dropped out after one episode to film
Mission: Impossible – Ghost Protocol, and was replaced by
Melissa Sagemiller in the recurring role of ADA
Gillian Hardwicke. Before the end of season twelve, Mariska Hargitay asked for a lighter workload. As a way of writing her out of certain episodes, a plan to have her character promoted to a supervisory role was discussed. At the end of season twelve, Christopher Meloni departed the cast, unable to reach agreement on a new contract. Warren Leight became the new showrunner during this same year and signed on before he knew that Meloni would be leaving the cast. The second major departure to be announced in 2011 was that of BD Wong. On July 17, Wong announced on
Twitter that, "I actually do not return for season 13, I am jumping to
Awake! It's awesome!" Wong added, "I don't know if or when I'll be back on
SVU! It was amazing to have such a cool job for 11 years and to be a real NY Actor." Wong reprised his role as Dr. Huang in season 13's episode "
Father Dearest". and Hargitay during the filming of the 13th season In June 2011, it was announced that
Kelli Giddish and
Danny Pino would join the cast as new series regulars. The launch of season 13 was marked with a retooling of the show that Warren Leight referred to as "SVU 2.0". Changes that accompanied this included Tamara Tunie's being bumped from the main cast to a guest-starring role and recurring actor
Joel de la Fuente's not appearing for the first time since 2002. Of the latter change, Warren Leight said, "those scenes [which featured Fuente] can be dry" and hired
Gilbert Gottfried as a more comedic replacement. In season 14,
Raúl Esparza joined the cast in a recurring capacity as ADA
Rafael Barba and prior to the season 15 premiere, Esparza was promoted to a series regular. Also in season 15, Belzer departed the cast in the fifth episode, "Wonderland Story", in which Sgt. Munch retired from the NYPD and took a job in the DA's office as an investigator. Later in the season, Captain Cragen announced his departure from the NYPD, which made newly promoted Sgt. Benson the temporary squad commander. In leaving the cast, Florek ended a 400-episode run as Captain Cragen. In season 16,
Peter Scanavino joined the series, first in a recurring role for episodes 1–3 and then was promoted to the main cast in episode 5, with Kelli Giddish, Danny Pino, Ice-T and Raúl Esparza. On May 20, 2015, it was revealed that Danny Pino would be leaving the cast after the season 16 finale "Surrendering Noah". In August 2017, it was announced that
Philip Winchester would recur in season 19 as ADA
Peter Stone, his character from
Chicago P.D. and
Chicago Justice, who is the son of
Benjamin Stone, the first ADA on the original
Law & Order series. It was later also announced that
Brooke Shields was enlisted to assume a major recurring role (Sheila Porter, maternal grandmother of Noah Porter-Benson, Olivia's adopted son) starting in season 19 of the long-running dramatic series. On February 7, 2018, Raúl Esparza left the series after six seasons. His role was taken over by Winchester. Upon being renewed for its twenty-first season, it was announced that Winchester would be departing the series after the twentieth season. In March 2019, it was announced that the show would come back for season 21, making it the
longest-running primetime American live-action series in the history of television. On May 16, 2019, the season finale aired and Winchester took to Twitter to thank the cast and crew for the send-off. After recurring for several episodes in season 21 as Vice Officer Katriona Tamin,
Jamie Gray Hyder joined the cast as a regular, starting in episode 8. On October 6, 2020,
Demore Barnes, who had recurred throughout season 21 as new Deputy Chief Christian Garland, was upgraded to regular status for season 22. On September 3, 2021, it was announced that Hyder and Barnes would both depart the series following the two-hour season 23 premiere. On October 13, 2021,
Octavio Pisano, who had guest starred since the start of the season, was promoted to regular status. On August 24, 2022, it was announced that Giddish would leave the series during the first half of season 24, with episode nine as her last appearance as a regular. On November 10, 2022,
Molly Burnett, who initially appeared in a recurring capacity for the first six episodes, was promoted to series regular beginning with the seventh episode. On May 19, 2023, Burnett announced that she will leave at the end of the show's twenty-fourth season. On November 28, 2023, it was announced Giddish would return for the twenty-fifth-season premiere. On July 22, 2024, it was reported
Kevin Kane, who portrays Terry Bruno, would be promoted to a series regular for the show's twenty-sixth season, after recurring the previous two seasons. On August 7, 2024, it was announced
Juliana Aidén Martinez, who would portray Kate Silva, was added as a series regular ahead of the season premiere. On May 6, 2025, it was announced Martinez and Pisano would depart following the conclusion of the twenty-sixth season. Nine days later, it was announced Giddish would return as a series regular for the twenty-seventh season. On July 18, 2025, it was announced Aimé Donna Kelly, who joined the series in the recurring role of Captain Renee Curry in 2020, had been upgraded to series regular ahead of the twenty-seventh season. Six days later, it was revealed Pisano would reprise his role for the season twenty-seven premiere. In August, it was announced Meloni, Florek, and Wong would reprise their roles of Stabler, Donald Cragen, and George Huang, respectively during the season.
Corey Cott joined the series as Detective Jake Griffin starting with the second episode of season twenty-seventh, later being promoted to a series regular in the ninth episode. Hargitay, Ice T, Scanavino, Giddish, Kane, and Kelly are all set to return for the series' 28th season. During season sixteen, Hargitay was reported to be earning $450,000 per episode, or $10,350,000 per season. In season seventeen, her salary increased to $500,000 per episode.
Filming and location at night Many exterior scenes of
Law & Order: Special Victims Unit are filmed on location in New York City, Wolf's hometown, throughout all five of
New York City's boroughs.
Fort Lee, New Jersey served as the filming location for Detective
Elliot Stabler's residence in
Queens, New York. The Archives building was used for police station and courtroom scenes, with various other locations in
Hudson County used for other scenes, such as a scene shot at the Meadowlands Parkway in
Secaucus in 2010. The production left New Jersey for New York in 2010, however, when New Jersey Governor
Chris Christie suspended the tax credits for film and television production for the Fiscal Year 2011 to close budget gaps. The show moved into the studio space at
Chelsea Piers that had been occupied by the original
Law & Order series until its cancellation in May 2010. In 2023, filming near the courthouses at
Foley Square coincided with media attention on the trial related to the
prosecution of Donald Trump in New York. During external filming in
Fort Tryon Park in 2024, it was reported that a young girl looking for her mother mistook Mariska Hargitay for a real police officer. ==Episodes==
