Lost Girls Budget
Updated
Synopsis
After her daughter disappears, Mari Gilbert's relentless investigation forces the Long Island police to uncover a string of unsolved murders along Ocean Parkway, exposing institutional failure to protect sex workers. Liz Garbus's Netflix narrative feature debut adapts Robert Kolker's 2013 nonfiction book.
What Is the Budget of Lost Girls (2020)?
Lost Girls (2020), directed by Liz Garbus and distributed by Netflix, was produced on an undisclosed budget estimated by industry sources in the $10,000,000 to $15,000,000 range. The film was financed by Netflix as a streaming exclusive in keeping with the platform's prestige true-crime acquisition strategy following the success of titles such as American Crime Story and Mindhunter. Producers Anne Carey (Adventureland, The Savages) of Archer Gray and Andrea Sperling (Tangerine, Transparent) of Sidney Kimmel Entertainment ran point on the project.
The budget supported a contained East Coast production, primarily in Long Island and New York, with Garbus making her narrative feature debut after a decorated documentary career (The Farm: Angola, USA; What Happened, Miss Simone?). The project deliberately operated at a mid-budget indie scale to preserve the documentary realism of the source material and to focus financial resources on the character-driven performances of Amy Ryan, Thomasin McKenzie, and Gabriel Byrne.
Key Budget Allocation Categories
The reported production cost was distributed across these areas:
- Above-the-Line Talent: Lead Amy Ryan (Gone Baby Gone, The Office, Birdman) anchored the production as Mari Gilbert. Thomasin McKenzie (Leave No Trace, Jojo Rabbit) played daughter Sherre Gilbert, Gabriel Byrne (In Treatment, The Usual Suspects) played Police Commissioner Richard Dormer, and Lola Kirke (Mistress America, Mozart in the Jungle) played daughter Sarra Gilbert. Director Liz Garbus, making her narrative debut, was paid as both director and producer.
- New York and Long Island Production: Principal photography ran in fall 2018 across Long Island (Mastic Beach, Babylon, Smith Point) and New York City locations, with the production qualifying for New York State Film Tax Credits. The actual locations of the unsolved murders, including the stretch of Ocean Parkway where the bodies were discovered, were used for key sequences.
- Documentary-Style Cinematography: Cinematographer Igor Martinovic (The Wrestler, House of Cards, McMafia) used a naturalistic, available-light approach that mirrored the documentary aesthetic of Garbus's prior work. The visual style emphasized handheld camera and natural light to maintain the source material's documentary realism.
- Production Design and Period Recreation: The film required recreation of 2010-2011 Long Island settings, including police interview rooms, the Gilbert family home in Ellenville, the Ocean Parkway crime scenes, and various Long Island police precincts. Production designer Christopher Trujillo built sets that captured the working-class Long Island milieu.
- Editing: Editor Kate Sanford (Treme, The Wire) shaped the film's 95-minute investigative structure, working closely with Garbus to maintain the procedural rhythm while preserving the emotional through-line of Mari Gilbert's grief.
- Music and Sound: Anne Nikitin scored the film with a sparse, melancholic approach that avoided thriller conventions in favor of grief-centered emotional weight, in keeping with Garbus's documentary sensibility.

Lost Girls Box Office Performance
Lost Girls premiered at the Sundance Film Festival on January 28, 2020 ahead of its Netflix launch on March 13, 2020 as a streaming exclusive with no theatrical release. The film's release coincided with the COVID-19 pandemic shutdown of mid-March 2020, which heightened its at-home viewership during the initial pandemic stay-at-home period.
Netflix did not publicly release viewership figures, but the film became a top-five most-watched release on the platform during its launch week and remained on the daily Netflix Top 10 in the United States for two consecutive weeks. The financial breakdown:
- Production Budget: approximately $10,000,000 to $15,000,000 (estimated)
- Estimated Prints & Advertising (P&A): absorbed into Netflix in-platform marketing (no theatrical P&A)
- Total Estimated Investment: approximately $12,000,000 to $18,000,000
- Worldwide Gross: not applicable (Netflix exclusive)
- Net Return: recouped through Netflix engagement metrics during the early pandemic streaming surge
- ROI: positive based on launch-window Top 10 performance and ongoing critical acclaim
Netflix's acquisition of Lost Girls fit the platform's 2019-2020 push to acquire prestige true-crime narrative features with name leads, alongside the contemporaneous releases of Marriage Story, The Trial of the Chicago 7, and The Two Popes. The film contributed to Netflix's establishment as a credible distribution outlet for character-driven indie drama.
Lost Girls Production History
Development on Lost Girls began in 2014 when producer Anne Carey of Archer Gray optioned Robert Kolker's 2013 nonfiction book Lost Girls: An Unsolved American Mystery. Kolker's book documented the 2010 disappearance of Shannan Gilbert and the subsequent discovery of remains belonging to ten victims along Ocean Parkway on Long Island, which became the unsolved Long Island Serial Killer case.
Liz Garbus, whose documentary career included What Happened, Miss Simone? and the HBO documentary series There's Something Wrong with Aunt Diane, was attached as director in 2017 following her work on related true-crime projects. Screenwriter Michael Werwie (Extremely Wicked, Shockingly Evil and Vile) adapted Kolker's book into a screenplay focused on Mari Gilbert's investigation rather than the broader serial killer mystery.
The Gilbert family was consulted during development, with Mari's daughters Sherre and Sarra providing input on the depiction of their mother and sister Shannan. Real-world locations were used where possible, including the actual stretch of Ocean Parkway where the bodies were discovered and the Ellenville, New York area where Mari Gilbert lived.
Principal photography ran for approximately eight weeks in fall 2018, primarily in Long Island and across New York State. Mari Gilbert had died in 2016 (killed by another daughter during a mental health crisis) before the film entered production, and the screenplay focused on a specific window of her investigation from late 2010 through 2011.
The film premiered at Sundance on January 28, 2020, where Netflix's acquisition was completed. The platform release on March 13, 2020 coincided with the COVID-19 shutdowns, and the film became a frequently cited reference point in 2020 discussions of streaming-exclusive distribution during the pandemic.
Awards and Recognition
Lost Girls received recognition primarily within the indie and documentary-adjacent awards circuits. Amy Ryan received Best Actress nominations at the Independent Spirit Awards. At the 2020 Gotham Awards, the film was considered in independent feature categories. Thomasin McKenzie received supporting actress attention from regional critics groups.
The film was selected as the U.S. Dramatic Competition opening film at the 2020 Sundance Film Festival, a slot that historically signals prestige acquisition interest. No major awards bodies (Academy Awards, Golden Globes, BAFTAs) recognized the film, with critics attributing the omissions to the streaming-exclusive distribution model and the pandemic-disrupted awards cycle.
Critical Reception
Lost Girls received positive reviews. The film holds an 85% approval rating on Rotten Tomatoes based on 161 critic reviews and a 69 out of 100 score on Metacritic. Critics praised Liz Garbus's documentary-realist direction, Amy Ryan's grounded lead performance, and the film's refusal to indulge in serial-killer thriller conventions in favor of grief-centered procedural realism.
Variety's Owen Gleiberman wrote that the film "treats its true-crime subject matter with the documentary humility Liz Garbus has perfected over two decades," while The Hollywood Reporter's Boyd van Hoeij praised Amy Ryan's performance as "a study in working-class grief that never tips into melodrama." IndieWire's Eric Kohn called the film "a procedural that prioritizes the families left behind over the killer's mythology."
Criticism focused on the film's deliberate refusal to resolve the central mystery (the Long Island Serial Killer remained unidentified at the time of release; suspect Rex Heuermann was not arrested until July 2023), which some reviewers found unsatisfying as a narrative structure. The New York Times's A.O. Scott noted that "the film's commitment to documentary realism produces both its power and its limitations." The film was nonetheless widely cited in 2020 as one of Netflix's strongest narrative acquisitions and a successful narrative debut for Garbus.
