At 20 years old, Dunham made her first short film, Creative Nonfiction, a satire of the New York art world, which she shot in her family’s home. The film’s acceptance into the Slamdance Film Festival in Park City, Utah, felt like the true beginning of her life. There, she and her friends met fellow undergraduate filmmakers Josh and Benny Safdie, whose talent and collaborative energy inspired her. She soon became an informal member of their New York-based film collective, Red Bucket, taking on any task to be near the creative process.

After graduating from Oberlin College, Dunham felt adrift, working a series of unfulfilling jobs while living with her parents. A year later, she found the angst-filled teenage journals of her mother, the filmmaker Laurie Simmons. The journal entries, revealing Laurie’s obsession with her weight, demeaning sexual encounters, and desperation to create a meaningful life, made Dunham see her mother as a kindred spirit. They prompted her to write the screenplay for the feature film Tiny Furniture, which she presented to her mother as a birthday gift.

With her mother serving as her champion and producer, Dunham cast her family and her friend, Jemima Kirke, in the film. It premiered to great acclaim at the South by Southwest Film Festival, winning the Grand Jury Prize. At the festival, she also met New York Times reporter David Carr, who became an important mentor. The win unleashed a flood of interest from Hollywood, and Dunham’s mother connected her with agent Peter Benedek. He arranged a series of meetings for her in Los Angeles, culminating in a pitch to HBO executives. There, she spontaneously proposed a show about the unglamorous, uncertain reality of post-college life for young women in New York. The executives were intrigued and offered her a blind pilot deal.

In New York, Dunham was introduced to potential supervisors for her HBO pilot. She immediately connected with writer Jenni Konner, who became her creative partner and mentor. Shortly after, she received a surprise email from acclaimed producer Judd Apatow, who loved Tiny Furniture and offered to join the project as an executive producer. Dunham flew to Los Angeles to begin writing with Konner, quickly developing an intense admiration for her new partner and beginning to emulate her style and mannerisms. The characters for the show, eventually titled Girls, were drawn from Dunham’s own life: The self-sabotaging Hannah was a version of herself, the pragmatic Marnie was based on her friend Audrey, and the mercurial Jessa was modeled on her friend Jemima Kirke.

The character of Adam was inspired by Dunham’s degrading sexual relationship with an older man, whom the author refers to as “the man with the cleft lip” (17). To impress him, she invited him as her date to a festival screening of Tiny Furniture at the Chateau Marmont hotel in Los Angeles. The film contained a reenactment of their first sexual encounter. At the after-party, Dunham discovered her date kissing another woman. Devastated, she got blackout drunk, leading to a deeply humiliating hangover the next day during a set visit for Apatow’s film, Bridesmaids.

In 2010, HBO officially ordered the pilot for Girls. Casting director Jennifer Euston was hired, and Dunham was surprised when the producers, including Judd Apatow and Jenni Konner, assumed that she would play the lead role of Hannah. For the other parts, Allison Williams was cast as the pragmatic Marnie, and Jemima Kirke agreed to play the bohemian Jessa. Zosia Mamet was cast as the quirky Shoshanna based on an audition tape. For the male leads, Christopher Abbott was cast as Marnie’s boyfriend, Charlie, while Adam Driver was chosen for the role of Adam, Hannah’s unpredictable love interest. Driver’s intense and feral audition captivated the creative team.

Production began at Silvercup Studios in Queens, and the pressure of being a 24-year-old showrunner immediately weighed on Dunham. A few weeks before filming, she collapsed from acute colitis, a stress-induced illness that marked her first major health crisis during production. After a table read of the pilot fell flat, Apatow and Konner helped Dunham rewrite the script, adding the key scene where Hannah’s parents cut her off financially. This collaborative breakthrough solidified their partnership. The first day of shooting was nerve-wracking, but Dunham found her footing. Nervous about her first sex scene with Adam Driver, she decided to get a Brazilian wax. The beauty treatment violated her feminist principles and left her with an unsightly rash. In the end, the sex scene was physically intense and largely unscripted, establishing a dynamic of trust with Driver that would define their on-screen work.

After filming wrapped, Dunham edited the pilot in Los Angeles, and HBO quickly picked up Girls for a full series. A writers’ room was assembled in LA to develop the remaining episodes. Adam Driver alarmed Dunham by not speaking to her for three weeks after seeing the pilot. He eventually called to explain that he hated watching himself on screen.

Prior to recording the first series of Girls, Dunham was overwhelmed by fear of failure and took Klonopin, an anti-anxiety medication, prescribed during her high school years. As a teenager, she used this medication after being raped at a party and during severe episodes of Obsessive-Compulsive Disorder (OCD).

After filming the first episode, Jenni Konner gave Dunham feedback on her weight loss, stating that it detracted from the show’s comedic voice and authentic appeal. Konner was unsympathetic when Dunham explained that anxiety had affected her appetite, instructing her to eat more. Dunham began gorging on junk food, gaining 15 pounds in a month. While recording the last episodes of season one, she experienced episodes of disassociation, a PTSD symptom that made her feel disconnected from her own body. During a rehearsal, Adam Driver became frustrated with her vacant and unresponsive state. He screamed at her and threw a chair against a wall, shocking her back to a state of presence.

With her first substantial paychecks, Dunham felt a sense of independence after fearing she would always be reliant on her parents. She found her first apartment in Brooklyn Heights, a dilapidated but charming one-bedroom. Famed writer-director Nora Ephron, who had become a mentor to Dunham after seeing Tiny Furniture, gave her precise instructions on how to renovate the space.

Soon after, Dunham returned to LA for three months to edit the first season. She sublet a termite-infested house in the Hollywood Hills but left after a frightening encounter with an aggressive stranger who pounded on the door demanding money. She relocated to the Sunset Tower, a hotel that would become a frequent refuge for her in the years to come. With a second season already green-lit, Dunham leased an apartment in the El Royale, a historic Hollywood building where she was closer to the writers’ room.

As the writers’ room for season two began, Dunham was forced to pull out of a separate film project with producer Scott Rudin due to scheduling conflicts. Rudin responded with a torrent of abusive emails threatening to sue her. The stress, combined with the pressure of the show, triggered a perforated eardrum.

Dunham’s father, artist Carroll Dunham, flew to LA to care for her, insisting she needed rest. She returned to New York, where the psychopharmacologist, whom Dunham had been visiting since the age of 12, prescribed Lexapro and Klonopin. During this time, Driver showed her an unexpected tenderness. Their relationship grew intense and fraught with unspoken romantic tension. One night, while his girlfriend was out of town, Driver told Dunham he was coming over to her parents’ apartment and implied he wouldn’t be leaving. She watched him arrive from her window but chose not to answer the door, realizing that crossing that boundary would destroy their professional dynamic and her authority as his director. A month later, he told her he was engaged.

The premiere of Girls received rave reviews, hailing Dunham as a major new voice. Just before the premiere, fashion designer Rachel Antonoff set Dunham up on a blind date with her brother, Jack Antonoff, a musician in the band fun. They connected immediately, bonding over their shared anxieties and cultural references. As the show aired, however, the public response was fiercely polarized. Dunham became a target for criticism about privilege, nepotism, and her physical appearance. The intense scrutiny affected her entire family, and her sibling, Cyrus, began to distance themself.

Amid the media storm, Jack became Dunham’s anchor. Their relationship deepened as he toured with his band, and he provided an important source of validation against the public’s vitriol. Three months in, they had their first sexual encounter, and soon after, they professed their love for each other. Meanwhile, the dynamics on the Girls set grew complicated, with Jemima Kirke struggling under the pressure of the show’s success.
