Elizabeth Buckley Harrold O’Donnell is best known publicly as the daughter of television host Lawrence O’Donnell and former actress Kathryn Harrold, but her own professional record tells a broader story. She is an actress, writer, and director who has trained at William Esper Studio, graduated from Harvard College, and built credits across television, theater, and short filmmaking. Her professional website identifies her as working in New York and Los Angeles.
Her career has also become easier to trace in recent years. Screen appearances in projects such as Curb Your Enthusiasm, Pam & Tommy, The Other Two, White House Plumbers, The Last Thing He Told Me, and Sugar sit alongside writing and producing work on Pillow Talk and the directing debut WHOA.
One point deserves particular attention: online biographies have sometimes confused Elizabeth’s background with that of her mother. The Antioch University master’s degree and California LMFT credentials belong to Kathryn Harrold, not Elizabeth. Elizabeth’s documented education and career instead center on Harvard, professional acting training, and creative work for the stage and screen.

Early Life and Family Background
Lawrence O’Donnell and Kathryn Harrold married on February 14, 1994, and their daughter Elizabeth was born later that year. Lawrence himself confirmed her birth year during a December 6, 2021 episode of The Last Word, when he was discussing childhood first words with Rachel Maddow.
The family brought together two very different professional worlds. Lawrence O’Donnell became a prominent television host, writer, and political commentator, while Kathryn Harrold established a long career in film and television before moving into a second career as a marriage and family therapist. Elizabeth subsequently entered the creative industries herself, making acting and filmmaking the center of her public professional identity.
Elizabeth has also spent part of her life around her father’s philanthropic work in Malawi. In a December 2016 broadcast, Lawrence said that his daughter had been with him in Malawi and had been present around the period when the K.I.N.D. Fund expanded to include scholarships for girls. His account provides a glimpse into her exposure to the project, although it does not establish a formal organizational role for Elizabeth.
A Rare Glimpse of Elizabeth’s Childhood
Elizabeth has largely remained outside the level of public exposure associated with her parents, so one of the clearest records of her childhood comes from an old home video shown on The Last Word.
During the December 6, 2021 broadcast, Lawrence O’Donnell explained that Elizabeth was born in 1994 and recalled that one of the first names she learned was Bob Dole. The program then showed childhood footage of Lawrence prompting his young daughter to repeat the name.
The clip is more revealing than a conventional celebrity biography because it shows the family dynamic directly rather than relying on recycled biographical details. It also demonstrates why Elizabeth’s name occasionally appears in connection with her father’s television career even though she has pursued a separate profession.
Education: Harvard College and William Esper Studio
Elizabeth’s education is one of the better-documented parts of her biography. The Codman Academy Foundation says she graduated from Harvard College in 2017 and then completed the Two Year Full Time Meisner Training Program at William Esper Studio. Her own professional website confirms the same educational path.
That combination places academic study and professional actor training side by side. Harvard provided the university setting, while William Esper Studio gave her focused training in the Meisner technique, an approach commonly associated with truthful, responsive performance.
Publicly available biographical material reviewed for this profile does not establish her Harvard field of study, so claims about a specific concentration or degree subject should not be treated as confirmed.
Elizabeth O’Donnell’s Television and Acting Career
Elizabeth’s public acting résumé is broader than a single breakout credit. Her professional materials list appearances across HBO, Showtime, Hulu, and Apple TV+ productions, while casting records provide more detail about several of her character roles.
Among the documented credits are Adele in Black Monday, a co-star role on Curb Your Enthusiasm, and Krogh’s Secretary in The White House Plumbers.
She also appears as Madeline in Pam & Tommy and is credited as a Publicist in The Other Two. These are supporting roles, but together they show continued work across scripted comedy and drama rather than a career confined to one genre.
The Last Thing He Told Me
A particularly visible recent credit is Apple TV+’s The Last Thing He Told Me. Elizabeth plays Ed, a character credited throughout the series. Cast records identify her in both the original 2023 season and the second season released in 2026.
The show’s second season premiered on February 20, 2026, according to Apple TV’s official press materials. The season contains eight episodes, and Elizabeth is listed in the cast as Ed.
The credit is notable because it places Elizabeth in a major streaming drama whose returning ensemble includes Jennifer Garner, Angourie Rice, Nikolaj Coster-Waldau, David Morse, and other established performers. Apple describes the second season as continuing Hannah and Bailey’s story after Owen’s return.
Sugar
Elizabeth also joined the second season of Apple’s mystery drama Sugar as Steff. Her official website specifically highlights her appearance in the show’s episode 205, and current episode records list her as Steff in Season 2, Episode 5, Unknowns, released in July 2026.
Apple says Sugar Season 2 premiered on June 19, 2026. The series stars Colin Farrell as private investigator John Sugar and combines a detective story with larger secrets surrounding the people he investigates.
Stage and Screenwriting
Elizabeth’s work extends beyond acting. Her public résumé includes theater appearances as well as writing credits, giving her career a distinctly cross-medium character. A professional casting profile lists theater work including Far Away, Five Times in One Night, Whisper Network, and the reading of There Are People That Are Dying.
She co-wrote There Are People That Are Dying with Justine Gelfman. According to Elizabeth’s professional website, Dixon Place hosted a sold-out one-night benefit reading of the play, with proceeds going to IndieSpace.
That stage work helps put her film writing in context: she has not simply moved from acting into one-off screen projects but has continued developing original material across live performance and film.
Pillow Talk: Writing About Friendship, Fear and Consent
Pillow Talk provides one of the strongest examples of Elizabeth’s work as both a writer and performer.
The short was directed by Mathilde Hauducoeur and written by Elizabeth O’Donnell and Annalisa Plumb, who also appear in the film. Brooklyn Film Festival describes it as a comedy-drama centered on Margot and Cami, two friends processing very different experiences involving intimacy, fear, and a confusing one-night encounter.
The story begins with Margot attempting to reenact moves learned in a self-defense class with her boyfriend. Her fears then spiral around what may have happened to her friend Cami. The two women eventually talk through their experiences, making their friendship the emotional center of the film.
The film’s festival history adds credibility to the project as more than an unpublished writing exercise. Elizabeth’s professional site says Pillow Talk screened at the Miami Film Festival, Brooklyn Film Festival, Indy Shorts, and New Hampshire Film Festival, and the film has also been made available through Short of the Week and NoBudge.
A review published by Short of the Week highlighted the film’s focus on female friendship, consent, personal safety, and the less clearly defined situations that can complicate questions of intimacy. That context helps explain the thematic direction behind Elizabeth’s writing work.
WHOA: Elizabeth O’Donnell’s Directorial Debut
Elizabeth’s transition behind the camera becomes even clearer with WHOA, which she wrote and directed. Her official website identifies it as her directorial debut.
The short is listed as a 2025 U.S. film with a runtime of 13 minutes. Its central premise is deliberately intimate: a mother and daughter take mushrooms together. Elizabeth serves as writer and director, while her mother, Kathryn Harrold, stars alongside her. Elizabeth is also credited as executive producer.
The project took on additional significance through its festival launch. Heartland Film’s 2026 Indy Shorts announcement identified WHOA as a world-premiere selection.
The mother-daughter casting creates a direct link between Elizabeth’s filmmaking and her family history, but the project is still distinct from a conventional celebrity-family appearance: Elizabeth is credited as the person who wrote and directed the story.
Fact Check: Elizabeth O’Donnell vs. Kathryn Harrold
Important correction: The frequently repeated claim that Elizabeth Buckley Harrold O’Donnell attended Antioch University and became a licensed marriage and family therapist is not supported by the reliable sources reviewed for this profile. Those credentials belong to her mother, Kathryn Harrold.
| Credential or career detail | Elizabeth O’Donnell | Kathryn Harrold |
|---|---|---|
| Harvard College | Yes; graduated in 2017 | Not established in the sources reviewed |
| William Esper Studio | Yes; full-time Meisner training | Not established |
| Actress | Yes | Yes |
| Writer/director | Yes | Not the documented primary profession |
| Antioch University | No reliable evidence found | Psychology Today lists attendance and graduation in 2011 |
| LMFT | No reliable evidence found | Yes; listed as MA, LMFT |
| Therapy practice | Not established | Documented professional practice |
Psychology Today identifies Kathryn Harrold as a Marriage & Family Therapist and says she attended Antioch University and graduated in 2011. By contrast, Elizabeth’s own professional biography identifies her as an actress, writer, and director, while Codman Academy documents her Harvard degree and William Esper training.
This is an important distinction for anyone researching the family online. Repetition across biography websites does not independently prove a fact, and in this case the available evidence clearly separates the mother’s therapist credentials from the daughter’s creative career.
