During an Emmy roundtable for "Hollywood Reporter" in 2014, Julianna Margulies revealed that she was only the third choice for the lead part on the show. Ashley Judd and Helen Hunt both turned down the part of Alicia.

Julianna Margulies wore a wig for her character Alicia and spent a reported fourteen hours a day, five days a week, and nine months out of the year working on the series.

All episode titles in seasons one through four have the same number of words as the number of the season in which they appear. All season one episodes have one-word titles (for example, Doubt), all season two episodes have two-word titles (for example, Real Deal), all season three episodes have three-word titles (for example, After the Fall), and all season four episodes have four-word titles (for example, Anatomy of a Joke). Later seasons reverse this formula. All season five episodes have three-words titles (for example, The Bit Bucket), season six's have two-word titles (for example, Dear God) and season seven episodes have one-word titles (for example, Taxed) completing the cycle.

The series was partly inspired by the Eliot Spitzer prostitution scandal. It also draws on other prominent American political sex scandals, such those of John Edwards and Bill Clinton. Creator Michelle King also noted that in these political scandals, the women are lawyers (Hillary Clinton, Elizabeth Edwards).

According to Julianna Margulies, after three exhausting years juggling the demanding show schedule and dealing with her baby's first years, she made a deal with Creators Robert King and Michelle King. Starting in season four, for those big courtroom scenes that take several hours to be filmed completely, Margulies would shoot the scenes where Alicia is an active part first, then they would shoot scenes with the other cast members, where she would have to be in the background for coverage once or twice, and then she would leave the set to prepare her next scenes, or have the rest of the day off.

Archie Panjabi, who played Kalinda Sharma, claims that when she was nominated for an Emmy award, nobody recognised her. She arrived on the red carpet to get her picture taken and "every single photographer in the line put their camera down".

On July 11, 2012, during the filming of an episode, in which she was guest-starring, Kristin Chenoweth was struck by a falling piece of lighting equipment. She was knocked unconscious by the blow, and was taken to the hospital in an ambulance. After several months of recovery, in which it was unsure if she would be able to return to her role, Chenoweth reported in September 2012 that her medical issues included not being able to "form a sentence after it happened", a skull fracture, and continuing pain in her ribs and hip.

During a 2011 interview on the National Public Radio program "Talk of the Nation," Alan Cumming (Eli Gold) confirmed that his character is loosely based on longtime political operative (and, as of 2011, Mayor of Chicago) Rahm Emanuel. Cumming said that Gold's undeveloped backstory includes a former career as a concert pianist, inspired by Emanuel's early-life, pre-politics ambition to become a professional ballet dancer.

Guest stars who have played themselves interacting with the show's fictional characters include: Clinton Administration advisers Vernon Jordan and Donna Brazile; Presidential MSNBC anchor and Political Commentator Chris Matthews; financial television hosts Lou Dobbs and Jim Cramer; and O.J. Simpson's lawyer and co-founder of The Innocence Project Barry Scheck. Actor, lawyer, and politician Fred Dalton Thompson plays Frank Michael Thomas, a thinly veiled version of himself (Thomas is also a former actor, lawyer, and politician). New York City Mayor Michael Bloomberg appeared in the season four finale.

The show is set in Chicago, but filmed in New York City. The pilot was filmed in Canada, and filming was planned to continue there, but Julianna Margulies asked the producers to shoot in New York City, because she had just become a mother, and couldn't leave for Canada for nine months a year.

The show earned two Emmy nominations in the Writing category, the first one for the pilot, and the second one for the series finale.

The show takes place in Cook County, Chicago, the same county as Cook County General Hospital, the setting of ER (1994), where Julianna Margulies played Nurse Carol Hathaway.

The show is based on Robert King & Michelle King's observation of real-life scandals. When they pitched the project, the couple noticed there were several occurrences of political scandals in which powerful women were involved. The question of why these women stay around, and what comes after public humiliation, formed the basis of The Good Wife.

Alan Cumming (Eli Gold) is Scottish, not American.

Julianna Margulies won two Emmy awards for her performance as Alicia Florrick - one in 2011 and one in 2014. She was nominated a total of four times.

Archie Panjabi could only play the character of Kalinda in boots. She stated: "I've tried wearing shoes, but it doesn't work. Her walk changes."

Up until the fourth season, all episodes had a title with its count of words increasing monotonically per season (effectively being equal to the season number). For example, season one episodes had a single-word title, season two episodes had a two-word title, et cetera. Beginning with season five, the title word-count started decreasing monotonically. For example, season five episodes have three-word titles, and season six episodes have two-word titles. It could be assumed that season seven is scheduled to be the last one, all episodes having again single-word titles.

Julianna Margulies' husband, Keith, is actually a lawyer.

There were seven writers, in addition to the Robert King & Michelle King, who worked on the show. Of those seven writers, three were also attorneys. The team had a legal consultant too.

Cush Jumbo (Lucca) joined the series cast in season seven after Christine Baranski suggested to Creators Robert King and Michelle King that they see her in the one-woman show "Josephine and I" (about jazz singer Josephine Baker) at New York's Public Theater in 2015. Cush had been an avid fan of the series from the very beginning.

Chris Noth, and guest stars Richard Brooks , Jill Hennessy, S. Epatha Merkerson, Fred Fred Dalton Thompson, Julianne Nicholson, Eric Bogosian, and Jay O. Sanders were all series regulars in the "Law & Order" franchise.

Michael J. Fox plays a lawyer with a neurological disorder (tardive diskinesia, rather than Fox's own Parkinson's, but close enough) which he plays up to gain sympathy from jurors he argues in front of. This backfires against a paraplegic judge in one episode: the judge basically says, "Yeah, so what?" and tells him to get on with the case.

By the time Archie Panjabi's Kalinda was written out at the end of season six, rumors had begun to circulate that she and Julianna Margulies did not get along on-set. When asked to comment on this rumor, Margulies explained that since Panjabi was simultaneously shooting segments her television series The Fall (2013) in the UK, the bar scene between both women in this show had to be filmed with body doubles in alternating over-shoulder reverse angle shots, and not because they couldn't bear to be in the same two-shots together. For her part, Panjabi has disputed this account of events, tweeting that not only was her new show not in production at the time, but that she was "in New York, ready to film the scene" in question.

Will's death was the result of actor Josh Charles' own decision to leave, not the creators' decision. Once he decided not to renew his contract, Robert King & Michelle King had to write around his exit.

Matt Czuchry, who plays Cary Agos, was unaware his character would be going to prison until he saw a prison jumpsuit in his wardrobe fitting.

Even the creators weren't convinced they'd be able to keep Will's (Josh Charles) death a secret. Michelle King claimed she was waiting for the secret to come out right up until the moment the show aired.

Kalinda's (Archie Panjabi) estranged husband, Nick (played by Marc Warren), left the show earlier than intended. It was clear his introduction had hit a wrong chord with fans. "You don't give James Bond a girlfriend," Robert King explained. "This was not a place where the audience wanted to go."

Josh Charles originally wanted to leave the show at the end of the fourth season. It was Julianna Margulies who convinced him to stay until mid-season so Robert King & Michelle King could write him a proper exit.

Season 7's campaign storyline was written to purposely mirror the current political stage. Robert King claimed "we're trying to parallel what's happening on our show with what's happening in reality."
