The Housemaid Was Self-Published First: How Freida McFadden Built a $400M Blockbuster

How a $35 million thriller grossed $400 million, proved franchise fatigue is real, and made the case that your favorite books should become movies.

As a thriller author whose own book is currently optioned and being turned into a film, I’ve watched the Housemaid box office numbers with the specific anxiety of someone whose career depends on this question working out.

Here’s a number that should make every thriller reader’s heart sing: $400 million.

That’s The Housemaid movie box office total—worldwide gross on a production budget of just $35 million. For context: that’s more than eleven times its cost. To put that in perspective: The Housemaid has now outgrossed Sinners ($380 million worldwide), Ryan Coogler’s star-studded vampire epic that cost nearly three times as much to produce. In a year where multiple $200M+ franchise films couldn’t break even, a single-location psychological thriller based on a self-published book became one of the most profitable movies of the decade.

I’ve already broken down what the movie gets right and wrong as an adaptation (read that craft analysis here). But as a thriller author whose book Perfect Modern Wife (click here if you want a free copy) has also been optioned for film, I can’t stop thinking about what The Housemaid means for the business of turning books into movies—and why every thriller reader should be paying attention.

Is The Housemaid Based on a Book? Yes — Here’s the Part Nobody Mentions

Yes. The Housemaid is based on Freida McFadden’s 2022 novel of the same name. Here’s what the box office coverage tends to leave out: McFadden had self-published eleven thrillers before the digital-first publisher Bookouture picked up The Housemaid, which came out in April 2022. McFadden (a doctor who specializes in brain injury) watched it spread through BookTok and Kindle Unlimited, and Hollywood came calling just three months after it came out.

That order matters. We’re used to the story going the other direction — studio option, script, then the book gets a cover redesign with a “Now a Major Motion Picture” sticker. McFadden’s version went: self-publish eleven books, sell the twelfth to a small digital publisher, land a film deal three months later. That’s not how it usually works, and anyone in publishing is paying very close attention.

The story itself: Millie (Sydney Sweeney) is a woman with a troubled past who takes a live-in housekeeping job with the Winchester family. Nina (Amanda Seyfried) is the wife. Andrew (Brandon Sklenar) is the husband. What unfolds is a cat-and-mouse about money, class, and what someone will actually do when the people who are supposed to protect her are the ones she needs to escape.

The movie changes the ending — and not accidentally. As someone currently watching my own book get developed for film, I’ve thought about this more than I probably should. The full book vs. movie breakdown is here if you want to go scene by scene.

The Housemaid is also book one of a trilogy — The Housemaid’s Secret (2023) and The Housemaid Is Watching (2024) follow. The sequel film is already greenlit. Worth reading all three before everyone else catches up.

The Housemaid Movie Budget vs Box Office: The Math That Terrifies Studio Executives

Let’s talk about money, because the money is where this story gets wild.

The Housemaid movie’s production budget was $35 million (per Box Office Mojo). By Hollywood standards, that’s tiny. For comparison, the average Marvel movie costs $200-350 million to produce. Captain America: Brave New World reportedly cost $180 million to make—and it was considered a box office disappointment.

The Housemaid movie grossed $126.4 million domestically and $273.6 million internationally, for a worldwide total of $400 million (The Numbers). Even with an estimated $35 million marketing spend (putting the total investment around $70 million) the return is staggering. That’s roughly a 5.7x return on total investment.

Why was the budget so low? Two words: single location. The vast majority of The Housemaid takes place inside one house. That’s the thriller genre’s secret weapon in Hollywood—psychological tension doesn’t require CGI armies or cityscape destruction. It requires good actors, a good script, and a locked door.

The New Jersey Connection: How Tax Credits Built a Blockbuster

Here’s a detail that rarely makes the entertainment press but tells you everything about how movies actually get made in 2025: The Housemaid filmed in New Jersey.

The Housemaid filmed in New Jersey, per the state’s film office (NJEDA), which lists it among the productions that shot there.

This is part of a massive shift in where movies get made, and the Housemaid movie is at the center of it. New Jersey offers 30-35% tax credits on qualifying production expenses (NJ Film Commission), and the state has been aggressively courting productions. Netflix is building its flagship East Coast production campus at Fort Monmouth—approved for up to $387 million in NJEDA tax credits (Netflix Studio announcement).

Meanwhile, Los Angeles (the traditional home of filmmaking) spent years watching productions leave for states with better incentives. California has since responded with a major expansion: Governor Newsom’s Program 4.0 raised the annual tax credit cap from $330 million to $750 million starting July 2025, and within six months generated $4.17 billion in economic activity (NBC News). But the damage was already done—productions had already built infrastructure elsewhere.

As someone who lives in LA with friends entirely in entertainment, I watch this tax credit chess match play out in real time. Where productions film determines where crews work, where local economies thrive, and which stories get greenlit based on what’s financially viable in which location. The Housemaid’s New Jersey shoot wasn’t just a production decision—it was a business model.

Franchise Fatigue Is Real—And Book Adaptations Are the Antidote

2025 was the year Hollywood finally had to reckon with franchise fatigue. Captain America: Brave New World and Thunderbolts both underperformed at the box office (Variety). Studios spent years betting that audiences would show up for any movie with a recognizable logo, and audiences finally called the bluff.

The standard Hollywood argument against “original IP” goes like this: audiences won’t take a risk on something they don’t already know. The counterargument has always been that audiences WILL show up for good stories—you just have to find them.

The Housemaid movie proves the counterargument with receipts. Call it “original IP” with an asterisk: it’s based on Freida McFadden’s 2022 bestseller, and the series has sold over 12 million copies and spent 100+ weeks on the New York Times bestseller list. That’s a built-in audience that doesn’t require a $100 million marketing campaign to educate. Readers already know the story, love the characters, and will pre-buy tickets.

After the Housemaid movie, book-to-film adaptations are quietly becoming Hollywood’s smartest investment (The Moving Words). The math is simple: bestselling books have proven narratives, tested emotional beats, and millions of people who already care about the outcome. Compare that to a $300 million franchise sequel where the creative process involves five credited writers and multiple rounds of reshoots. Which sounds like the better bet?

The Housemaid Cast: Two Generations, Two Audiences, One Opening Weekend

The casting of The Housemaid movie was quietly brilliant from a business perspective.

Sydney Sweeney (Millie) is one of the defining faces of Gen Z entertainment—Euphoria, The White Lotus, Anyone But You. Amanda Seyfried (Nina) has been a staple since Mean Girls and Mamma Mia!, with serious dramatic credibility from The Dropout (full cast on IMDb).

That’s two demographics in one movie. Gen Z buys tickets because of Sweeney. Millennials buy tickets because of Seyfried. Both groups already overlap heavily with the BookTok audience that made McFadden famous. The result: a wider opening weekend than any single-star thriller could have achieved.

Add Brandon Sklenar as Andrew and Michele Morrone as Enzo, and you have a cast that generates social media conversation across multiple fandoms. This is strategic casting for the algorithmic age, where each actor’s fan base becomes a distribution channel.

The Audience Hollywood Keeps Ignoring (Who Keeps Showing Up Anyway)

There’s a conversation I keep having with friends who work in development: where are the movies for women to see together?

Not romantic comedies (though we love those too). Not prestige dramas with one strong female lead. I’m talking about event movies—the kind you text your group chat about on opening weekend, the kind that generate the same communal energy that Marvel used to create for a completely different audience.

There have been some Colleen Hoover adaptations—It Ends with Us performed well, though the behind-the-scenes drama overshadowed the film itself. But actual thrillers for women friends to see together? That market has been wildly underserved.

The Housemaid movie proved this audience exists and will show up in force. $400 million in force. The same women who made BookTok a publishing industry force, who turned Freida McFadden from self-published to phenomenon, who spend their book club nights dissecting unreliable narrators over wine—they went to the theater. In groups. On opening weekend. And then they went back.

If Hollywood is smart (a big if), The Housemaid’s success opens the floodgates for more thriller adaptations aimed at this audience. The pipeline of source material is massive: there are hundreds of bestselling psychological thrillers published in the last five years alone, each with a built-in readership, each filmable on a modest budget, each with a BookTok fandom ready to convert into ticket sales.

The Housemaid Sequel 2026: What Comes Next (And Which Books Should Be Next)

Lionsgate moved fast. In January 2026 (barely a month after the film’s theatrical release) they greenlit The Housemaid’s Secret, based on the second book in McFadden’s trilogy (Deadline). Sydney Sweeney is set to return as Millie and will also executive produce. Paul Feig will direct again from a script by Rebecca Sonnenshine. Hooked on her style? Here are books like Freida McFadden to read while you wait. Michele Morrone is also expected to reprise his role as Enzo (Variety).

The speed of this greenlight tells you everything about how the industry views this property. Studios don’t rush sequels for movies they consider flukes. They rush sequels for movies they consider franchises. And a trilogy of bestselling books means the source material is already written—no development hell, no writers’ room, no “we need to figure out the story” delays.

Update (March 23, 2026): Lionsgate just announced that Kirsten Dunst will join the cast as Mrs. Wendy Garrick—the reclusive new employer whose marriage becomes Millie’s next obsession (Deadline). It’s another brilliant casting move: Dunst brings the same millennial-crossover appeal that Seyfried brought to the first film, plus indie drama credibility from The Power of the Dog and Civil War. The franchise is building a murderers’ row of actresses who can play women hiding something behind a perfect facade.

For readers, the sequel is exciting for different reasons. The Housemaid’s Secret shifts the dynamic entirely—Millie is studying social work, cleaning house again, and gets pulled into a new employer’s dangerous marriage. The claustrophobia moves from one house to another, and the stakes escalate because we now know what Millie is capable of.

But beyond the McFadden trilogy, The Housemaid’s success should greenlight a wave of book-to-film thrillers. Here are five books I’d love to see adapted next, each of which fits the same formula: modest budget, single or limited locations, massive existing readership, and stories built for the female audience that Hollywood keeps underestimating:

Behind Closed Doors by B.A. Paris

The closest tonal match to The Housemaid’s film potential. A perfect marriage, a beautiful house, and a secret so dark the reader can’t breathe. Single location. Two leads. Ready to shoot tomorrow. Film status: In development with director Robert Schwentke attached (Deadline).

The Silent Patient by Alex Michaelides

A woman who shoots her husband and never speaks again. A therapist obsessed with understanding why. The twist would be a cultural event on screen. Low-budget friendly with a therapy office as the primary set. Film status: Adaptation in development at Plan B Entertainment with Brad Pitt’s production company attached.

The Last Thing He Told Me by Laura Dave

Already adapted as a limited series on Apple TV+ starring Jennifer Garner, and it proved that thriller audiences will follow a female-led mystery across episodes. The book-to-screen pipeline works in multiple formats.

The Maid by Nita Prose

A neurodivergent hotel maid who discovers a body. Charming, surprising, and the kind of character that makes audiences root hard. Another single-location thriller with a built-in fanbase. Film status: In development at Universal Pictures with Florence Pugh attached to star (Deadline).

None of This Is True by Lisa Jewell

A podcaster meets a stranger who wants to be her next subject. The stranger’s story gets darker with each session. Dual timelines, mounting dread, and a twist that works even better visually than on the page.

Why I Wrote a Book for This Exact Audience

I’m going to be transparent here, because this is my newsletter and transparency is the point.

The Housemaid’s success excites me as a reader and personally validates me as a writer. My novella, Perfect Modern Wife, was written for exactly this audience: women who watch thrillers together, who discuss the dark underbelly of modern womanhood over drinks, who want stories that are fun and sharp and mean something. It’s a psychological thriller about a wellness influencer whose curated life hides something much darker—and it’s been optioned for film/TV, with director Joanna Tsanis attached to the project.

I designed it with the same math in mind: limited locations. A story that works on a modest budget. A premise that fits the cultural moment (wellness culture, influencer culture, the gap between curation and reality). The kind of thriller that a group of friends could watch on a Friday night and argue about afterward.

Living in Los Angeles with friends entirely in entertainment, I see firsthand how these decisions get made. The Housemaid’s $400 million is a proof of concept that changes the risk calculus for every book-to-film pitch meeting happening right now. Including mine.
