John James Preston, commonly known as "Mr. Big" or just "Big", is a recurring character in the HBO series Sex and the City, the follow-up film of the same name and its sequel, and sequel series And Just Like That..., portrayed by Chris Noth. He is the primary on-and-off love interest and later husband of the series' protagonist, Carrie Bradshaw.

Mr. Big first appeared as a recurring character and love interest of Carrie in Candace Bushnell's column "Sex and the City" in The New York Observer.^[1] Bushnell based Mr. Big on Ron Galotti, the former publisher of GQ and Talk, whom she had dated.^[2] Bushnell told New York Magazine in 2004, "He was one of those New York guys with a big personality—you just notice him as soon as he walks in the room," and "I called him Mr. Big because he was like a big man on campus."^[3]

"Big" appears in the first episode of Sex and the City as a very attractive stranger who helps Carrie pick up the contents of her purse (notably cosmetics and condoms) after she is accidentally bumped by a stranger on the streets of Manhattan. The nickname "Big" refers to his status as a "major tycoon, major dreamboat, and majorly out of [Carrie's] league," according to the show's dialogue. (His real name is not revealed to viewers until the final episode of the series; in a running joke, whenever Carrie is about to introduce Mr. Big to another character onscreen, she is interrupted before she can say his name.) When Carrie and her friend Samantha bump into Big at a nightclub, Samantha tries to hit on him, but he tactfully declines. In the first few episodes, he and Carrie frequently bump into one another, until finally Big suggests the two of them should "bump into one another on purpose". Carrie agrees and thus begins their on-again-off-again relationship. Big calls Carrie by the nickname "Kid". When Carrie asks Big if he has ever been in love, he replies, "Ab-so-fucking-lutely".

Carrie eventually falls in love with Big, despite his fear of commitment. His reserved communication on relationship issues and Carrie's coping with the ambiguity are frequent plot devices. Carrie repeatedly returns to the relationship even though he is clearly emotionally unavailable to her and unable to meet her needs. It appears Mr. Big was emotionally crippled by a series of failed relationships. He has a tendency to take major emotional steps in the relationship more slowly than Carrie, which is depicted as a result of emotional unavailability. Carrie's interpretation of Mr. Big's inner turmoil as unreachable distance often creates larger issues because of her misplaced feelings of unworthiness, and due to her propensity for not communicating truthfully until too late, results in a lot of painful misunderstandings. Carrie can be un-empathetic and often issues ultimatums (i.e. first break-up), and Big can't shed his ingrained emotional pessimism to fully embrace Carrie as a partner. They break up repeatedly, over the course of two years for those reasons, before Big marries a twenty-six-year-old socialite and Ralph Lauren employee named Natasha (Bridget Moynahan) after dating her for only five months. This hurts Carrie, as she wonders why he could take steps with Natasha that he refused to take with Carrie. It becomes obvious later that Mr. Big had simply skipped many of the important emotional steps before marriage, many of which he had definitely, if slowly, taken with Carrie. Ironically this creates the problems of distance and unavailability between Big and Natasha, which Carrie had so feared in their own relationship.

Within seven months of his marriage, he begins to chafe at his matrimonial bonds and pines for Carrie; he initiates an affair with her. Carrie, who is in a committed relationship (with Aidan Shaw) at the time, feels guilty but continues to see Big. The affair continues until Natasha comes home unexpectedly and discovers Carrie fleeing—half dressed—from the marital apartment. Natasha trips and breaks her tooth while chasing after Carrie, who ends up taking Natasha to the emergency room. As a result, Carrie ends the affair. Carrie later finds out that Big and Natasha have divorced.

Big and Carrie eventually become close friends. He relocates to Napa Valley, and they are able to discuss their other ongoing relationships with each other. But their sexual chemistry always remains just below the surface, and their friendship never remains strictly platonic. After reading Carrie's book, Big begins to understand how much he has hurt her, and he empathizes further when a famous actress he is dating treats him in a fashion similar to the way Big has treated Carrie: at arm's length, eschewing true intimacy. The relationship between Big and the celebrity is certainly a parallel between Carrie/Big, except that the celebrity refuses physical intimacy one-sidedly, ignoring Big's overtures except when it suits her, whereas Carrie/Big's problems were almost completely emotional and arguably two-sided. The experience ends up allowing Big to finally get past his inner pain. Big grows as an emotional being, changing and evolving as the series progresses, moving past innate pain to suit Carrie's needs better, ostensibly becoming a "better man."

Big seems to have no real friends, at least in New York. He is rarely shown with other males, and when he is, they are usually credited as colleagues or acquaintances. In one scene in the first film, he is shown at a New Year's Eve party alone, eating while the celebration goes on around him, but seems to feel comfortable with the situation.

The series finale, "An American Girl in Paris", ties together the loose ends of Carrie and Big's relationship and concludes their long, unconventional courtship. Absent for most of season six, Big suddenly reappears in Carrie's life near the end of the season, once again at the wrong time. At this point, Carrie has grown tired and frustrated with Big's inconsistency and angrily rebuffs him, but also realizes her behavior towards him has often pushed him away. However, Big is desperate to win Carrie back. The season finale depicts his attempt to reunite with her.

The series finale takes place over two episodes in which Carrie moves to Paris with her current boyfriend, Russian artist Aleksandr Petrovsky (played by Mikhail Baryshnikov). In the first half of the finale, "An American Girl in Paris Part Une", Big shows up outside Carrie's apartment in New York after she fails to return his phone calls. She is on her way to her last dinner with the girls before departing for Paris. Big attempts to invite Carrie to dinner and drinks in order to apologize for the way he treated her, only to be turned down. Carrie explains that she is moving to Paris with a man she's in a relationship with. Big asks Carrie when she was going to tell him that she was moving to Paris, a reference to the time earlier in their relationship when Big moved to Napa and almost didn't tell Carrie. Big teases her about moving to Paris with a Russian and then tries to tell her that she's "The One". Carrie loses her temper and tells Big that she is tired of having him interrupt her life and ruin her happiness for the past six years. Then she rushes off to meet her friends for dinner, leaving Big alone and confused on the street.

When Charlotte stops by Carrie's apartment one day, she hears Big leaving a message on Carrie's answering machine, asking her for one last chance. Charlotte picks up and invites him to meet with her, Miranda, and Samantha. At a restaurant, he asks them if they think Carrie really is happy and if he has any shot of winning her back. After much deliberation, with Carrie's current situation and her history with Big in the forefront of their minds, Miranda tells him to "go get our girl". Mr. Big then does not appear again until the second installment of the finale, "An American Girl in Paris Part Deux".

Meanwhile, Carrie is distraught and unhappy in her relationship with Aleksandr. She passes Big in his limo on the street in Paris while looking for a cab, but neither of them see each other. Big appears to be searching for Carrie, but the limo rides on and Carrie continues on her way.

Big reappears in Carrie's hotel lobby at just the right moment, as Carrie is squatting down, tearfully gathering up stray diamonds from her broken necklace. She is waiting for a new hotel room, as she just walked out on Aleksandr after a big fight. Big comes through the door and as Carrie looks up and sees him, she begins to cry. She explains that everything is a mess and Paris isn't what she thought it would be. Then she tells Big that Alexandr slapped her during an argument (though it was an accident when he turned around too fast and she was standing behind him). Big becomes protective and immediately begins climbing the stairs to Aleksandr's room to reprimand him (or as he puts it, "kick some Russian ass"). In a desperate attempt to stop him, Carrie trips him and they both fall to the floor, laughing hysterically. They give up seeking out Petrovsky and take a romantic stroll in Paris. He finally tells her she's the one and she asks him to take her home to New York. They arrive at Carrie's apartment late at night and she asks him if he wants to come up. He answers with a line he used in the first episode, "abso-fucking-lutely".

His real name, John, is finally revealed on Carrie's cell phone caller ID after she returns to the city and he calls to tell her he is closing the sale of his Napa estate and returning to New York. Executive producer Michael Patrick King has stated that by never revealing his real name, Big remained "always slightly out of reach" for Carrie, and this plot device is maintained throughout the entire run of the series. Although his name is seen in that final shot, King makes a point in the DVD commentary that it is never spoken in the series.

After 10 years of dating on and off, Carrie and Big are searching for an apartment together and decide on an idyllic and expensive penthouse. Carrie becomes anxious about what rights she would have if they were to ever break up, so Big proposes they marry. They initially plan for a small wedding for 75, but after Carrie is invited to appear in a Vogue photo shoot in bridal couture and receives an extravagant Vivienne Westwood gown as a gift, her plans for the wedding expand considerably.

Big expresses disapproval of the ballooning wedding, calling it a "circus," but reiterates he loves Carrie and still wants to marry her. His anxiety takes hold, however, when he runs into Miranda after an argument with her estranged husband. Miranda tells him that marriage ruins everything, and the next day Big gets cold feet and leaves the wedding venue before the ceremony. He tells Carrie he cannot go forward with the marriage, but comes to his senses a few minutes later and attempts to intercept Carrie as she flees the wedding venue. Broken-hearted and humiliated, Carrie attacks him with her bouquet, despite Big's repeated attempts to apologize, and she leaves for their honeymoon with her friends.

When Carrie returns, she discovers several emails and voicemails from Big, but asks her new assistant, Louise, to sever all contact with him and send his messages somewhere that Carrie won't have to see them.

Several months later, Big encounters Charlotte, who is nearly nine months pregnant, at a restaurant. She angrily confronts him, but then goes into labor. Big rushes her to the hospital and waits for hours, hoping to see Carrie, but ultimately leaves. She later appears at the penthouse he had purchased for them, determined to retrieve a pair of Manolo Blahnik shoes she had left behind, and finds Big there. Overcome with emotion, she embraces him and they reconcile. Big proposes again and they marry simply at City Hall, then celebrate with friends at a diner.

Carrie always wants to go out, while Mr. Big would prefer to stay home and watch television some evenings. After Carrie returns to her old apartment to work on an assignment and their reunion is particularly sweet, Big proposes to be separated for two days in the week, with one of them staying in Carrie's old apartment, which she has always kept. Carrie agrees, despite misgivings and questioning by Charlotte.

In Abu Dhabi, Carrie runs into her former love Aidan. Carrie and Aidan dated twice. They broke up the first time because Carrie and Big had an affair. They broke up a second time because Aidan still couldn't trust her after all that time due to her affair with Big, and after Aidan proposes, marriage doesn't sit well with Carrie, so the two break off their engagement. Aidan is now married with three boys and is in Abu Dhabi on business. The two agree to meet for dinner, despite warnings from Charlotte, who feels that Carrie is "playing with fire". Aidan and Carrie kiss before Carrie breaks away and runs to her hotel. Distraught about what to do, she eventually calls Big to confess to the kiss. He becomes distant and won't return her phone calls.

When Carrie returns to New York, the apartment is empty and she sits all day waiting for Big to come home. He finally returns that evening with her "punishment": Carrie must wear a black diamond ring to remind herself that she is married. The two reconcile and kiss. The film concludes with a montage of scenes from the girls' lives - Big and Carrie have successfully combined their desires and interests, and the two are content as their married life has grown past the "Terrible Twos".

In "Hello It's Me", the first episode of And Just Like That..., Big suffers a fatal heart attack after a vigorous workout on his Peloton bike. Carrie finds him collapsed in the shower after she returns home from Lily's piano recital. She finds him under the running water and he dies in her arms.

Despite Big dying in the first episode, Noth was set to appear as Big in a fantasy sequence in the season finale, but after sexual assault allegations were brought against him, he was edited out.^[4]

In response to the first episode of And Just Like That... featuring Big's death after using his Peloton bike, the company contacted Noth, Peloton instructor Jess King (who appeared as the fictional instructor "Allegra" in the episode) and Ryan Reynolds to film a sequel commercial for Peloton over the following 48 hours. In the commercial, titled He's Alive, Noth mentions faking his death in order to run away with King, a reference to the plot of the episode, before inviting her for a duel Peloton workout, as Reynolds narrates, confirming that "He's Alive."^[5] The ad was later removed due to sexual assault allegations against Noth.^[6][7]
