Early Life and Education of Kelly O’Sullivan
Kelly O’Sullivan was born and raised in Little Rock, Arkansas, to a mother who worked as an accountant and a father in the health insurance industry. Growing up in an Irish Catholic household, she attended Immaculate Conception school through the eighth grade. Her passion for acting ignited at a very young age; with the encouragement of her cinephile parents, she began performing in local children’s theater productions from the age of five. This early exposure to the stage was transformative, offering her a sense of community and open-mindedness that contrasted with her more traditional Catholic school upbringing. The collaborative nature of theater resonated deeply with her, fostering a sense of working towards a common goal. Determined to pursue acting professionally, O’Sullivan chose to attend Northwestern University for its esteemed theater program, which also allowed for a broader liberal arts education. After graduating from Northwestern, she further honed her skills by attending The School at Steppenwolf Theatre Company in Chicago, a prestigious institution known for its ensemble-based approach to acting.
Kelly O’Sullivan’s Career
Kelly O’Sullivan’s career began on the stages of Chicago, where she became a fixture in the city’s vibrant theater scene. She was an ensemble member at the American Theater Company and graced the stages of renowned institutions like the Steppenwolf Theatre, the Goodman Theatre, and Writers Theatre. Her stage credits are extensive, including roles in productions such as BLKS, The Humans, The Crucible, and The Seagull. Her talent was recognized with a Princess Grace Fellowship Award and nominations for a Barrymore Award and a Joseph Jefferson Award for her theatrical work.
While building her theater career, O’Sullivan also ventured into film and television, with appearances in shows like Sirens, The Mob Doctor, and Battleground, and in independent films such as Henry Gamble’s Birthday Party. However, a sense of frustration with the roles she was auditioning for, which often felt limiting, spurred her to take control of her own narrative. Inspired by the success of Greta Gerwig’s Lady Bird, she decided to write a screenplay that would provide a complex and authentic role for herself.
This endeavor resulted in the screenplay for Saint Frances. She began writing in January 2018, drawing heavily from her personal experiences as a nanny in her twenties and an abortion she had in her early thirties. The film, directed by her partner Alex Thompson, tells the story of Bridget, a 34-year-old woman who takes a job as a nanny for a precocious six-year-old girl named Frances. The narrative candidly explores themes of female relationships, postpartum depression, and the emotional and physical realities of abortion. O’Sullivan’s heartfelt and humorous performance in the lead role, coupled with her sharp and honest writing, garnered critical acclaim. Saint Frances premiered at the 2019 SXSW Film Festival, where it won both the Audience Award for Narrative Feature and a Special Jury Prize for “Breakthrough Voice.” This success launched O’Sullivan onto the international stage, earning her a Gotham Award nomination for Breakthrough Actor and a John Cassavetes Award nomination from the Independent Spirit Awards. She was also named one of Filmmaker Magazine’s “25 New Faces of Independent Film.”
Following the success of Saint Frances, O’Sullivan continued to act in films like Cooper Raiff’s Cha Cha Real Smooth. She then stepped behind the camera, making her directorial debut with the short film “My Summer Vacation.” Her next major project was Ghostlight, which she co-wrote and co-directed with Alex Thompson. The film, which premiered at the 2024 Sundance Film Festival, follows a construction worker who finds solace and a way to process family tragedy by joining a community theater production of Romeo and Juliet. Her upcoming project, Mouse, which she also co-wrote and co-directed with Thompson, is set to explore the complexities of a friendship between two high school girls in her home state of Arkansas.
