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 (Hilary Clinton, Elizabeth Edwards).
Julianna Margulies wears a wig for her character Alicia and spends a reported 14 hours a day, five days a week, and nine months out of the year working on the series.
During a 2011 interview on the National Public Radio program "Talk of the Nation," Alan Cumming (who plays 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.
On July 11, 2012, during the filming of a "Good Wife" episode in which she was guest-starring, actress 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.
Guest stars who have played themselves interacting with the show's fictional characters include: Clinton Administration advisors Vernon Jordan and Donna Brazile; presidential MSNBC anchor and political commentator Chris Matthews; financial TV hosts Lou Dobbs and Jim Cramer; and OJ Simpson lawyer and co-founder of The Innocence Project Barry Scheck.

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 4, for those big courtroom scenes that take several hours to be filmed completely, Margulies would shot the scenes where Alicia is and active part first, then they would shot scenes with the other actors where she would have to be on the background for coverage once or twice and then she would leave set to prepare her next scenes or have the rest of the day off.

Luke Kleintank was hired originally for the role of Brian Keller, but the role was re-cast because Kleintank looked too much like another one of the actors in the show.
Series star Josh Charles also starred in a movie called "Threesome" in 1994.
This episode originally contained a scene in which Kalinda and Burton were kissing and Kalinda was stung by a bee, which sent her into severe anaphylactic shock. On the DVD special features, the showrunners say that this scene was ultimately cut because it was too "silly" and also too much of a departure from the main storyline.
During the bar association gala, the attendees are entertained by the Steppenwolf Theatre Company performing scenes from a play called "The Cow with No Country." Although Steppenwolf is a real (and acclaimed) Chicago theater company, there is no such play as "The Cow with No Country" (although the short pieces included during the gala scene show that it is a parody of the play "War Horse").
The "Innocence Project," for which Cary is said to have interned, is a real organization that was founded in 1992 to assist and exonerate wrongly accused prisoners who could be proven innocent through DNA testing. One of the cofounders of the project, Barry C. Scheck, appears as himself in a cameo in this episode.
Originally, titled "Last Shot" however, it was retitled after the press release, so internationally (english language markets) it is still listed as that.
At 10.5 minutes, the pre-title-sequence is one of the longest ever in any 1 hour (including commercials) drama series. It takes about 25% of the actual running time.

The title of this episode, as well as much of the story, is based on a real system, also called "Bitcoin." Bitcoin is a decentralized electronic monetary and payments system utilizing peer-to-peer networking, electronic signatures and encrypted proof which enables supposedly irreversible payments between parties without requiring trust. Made in Bitcoins (abbreviated BTC), said payments are made by electronic (or digital) monetary instruments, or currency, which are originated and electronically transferred by the Bitcoin network.
SPOILER: In the show Mr. Bitcoin turns out to be 3 people (Mr. Stack, Boa and Elaine). In reality, the identity of Bitcoin creator is unknown. He is only known by pseudonym "Satoshi Nakamoto". There are hypotheses that it could be 2 or 3 people.
SPOILER: Kalinda tracks down Elaine by doing linguistic analysis of texts written by Mr. Bitcoin. She finds her by the phrase "theoretically established combinatorial properties". In reality, some journalists attempted to track down Satoshi by searching for certain phrases that he used in his publication. In this way they found several possible candidates, but all of them denied any connection to the creation of Bitcoin. The phrase was "computationally impractical to reverse".
