The Housemaid’s Secret Sequel Is Official: Cast, Story Basis, and 2026 Production Info

The domestic-thriller franchise that started with The Housemaid is officially expanding: Lionsgate has confirmed a follow-up film titled The Housemaid’s Secret. If you’re looking for the latest on the sequel’s cast, what book it’s based on, and what a 2026 production start really means, this post gathers everything confirmed so far (plus what’s still rumor).

Quick status: confirmed sequel, early-stage development, no release date announced yet.

The Housemaid’s Secret: Sequel Confirmed

Lionsgate has greenlit The Housemaid’s Secret as the next film in the series, following the box-office success of The Housemaid. The studio announcement frames it as a direct continuation of Millie’s on-screen story, drawing from Freida McFadden’s second book in the Housemaid series.

The big practical takeaway: Lionsgate has publicly targeted a 2026 production start. That does not automatically mean a 2026 release, but it does mean the project is moving beyond “wishful thinking” into real scheduling.

Cast & Creatives: Who’s Returning for The Housemaid’s Secret?

As of now, the sequel’s headline is continuity: the studio is aiming to keep the key team intact. The returning faces (and the returning behind-the-scenes talent) matter because the tone of The Housemaid depends on tight control of perspective, pacing, and that “wait—what did I just see?” twist rhythm.

Confirmed / strongly indicated returns

Role Name Status Why it matters
Millie Sydney Sweeney Returning (and executive producing) Millie is the anchor; the sequel is built around her next “perfect job” that isn’t perfect.
Enzo Michele Morrone Returning Enzo is positioned as a key ongoing relationship in Millie’s orbit.
Director / Producer Paul Feig Returning Feig’s glossy-but-sinister style is part of the brand identity now.
Screenwriter Rebecca Sonnenshine Returning Same adapter = better odds the sequel keeps the first film’s voice and structure.
Author / EP Freida McFadden Returning as executive producer Keeping the author involved can help protect the “why this works” core of the story.

What about Amanda Seyfried (Nina) and Brandon Sklenar (Andrew)?

The sequel’s source novel shifts focus to a new household, so Nina and Andrew are not expected to be central in the same way. That said, Amanda Seyfried has publicly expressed interest in a cameo, and cameos are exactly the kind of “blink and you miss it” continuity move franchises love once a series takes off.

Story Basis: What The Housemaid’s Secret Is About (Book 2, Spoiler-Light)

The sequel film is based on The Housemaid’s Secret, the second novel in Freida McFadden’s Housemaid series. The premise keeps the same core engine—Millie needs a job, a wealthy home looks like salvation, and the “rules” of the house feel wrong the second you hear them.

The book’s hook (and the part most likely to define the movie’s trailer moments): Millie is hired by the wealthy Garricks in a stunning penthouse, but she’s warned not to go into the guest bedroom—because the wife is “very ill.” Millie starts noticing signs that something darker is going on behind the locked door, and she decides to intervene.

How the sequel’s setup differs from The Housemaid (without spoiling twists)

  • New employers, new rules: the tension comes from fresh house dynamics, not repeating the exact Winchester beats.
  • Locked-room dread: the guest bedroom becomes the story’s “gravity well.”
  • Millie is changed: she’s no longer walking in naive—she’s walking in experienced, which changes the chess game.

2026 Production Info: What We Know (and What We Don’t)

Lionsgate’s public line is a 2026 production start. As of today (February 5, 2026), there’s no official release date, no confirmed filming location, and no full cast list beyond the key returning names.

A realistic “what happens next” timeline

  • Script + packaging: finalizing the screenplay and locking in returning leads and producers.
  • New casting announcements: the Garrick household will require major new roles.
  • Scheduling + locations: once locations and shoot dates are locked, trades usually start reporting specifics.
  • Principal photography: once cameras roll, expect the first set photos and teaser marketing.
  • Release window talk: only after filming is set (or underway) do studios typically start planting a date.

If you’re tracking “will it be out in 2026?”, treat that as speculation until Lionsgate dates it. A 2026 shoot often points to a 2027 theatrical release, but the schedule depends on when in 2026 production starts and how effects-heavy (or not) the final cut is.

Before the sequel marketing begins, the easiest way to recalibrate the franchise vibe is to rewatch the first film’s official trailer: glossy wealth, claustrophobic domestic spaces, and a constant sense that someone is performing.

What Reddit Reactions Say About The Housemaid Franchise Right Now

One useful way to predict how a sequel will be marketed is to watch what audiences latched onto the first time: which scenes became memes, what people call “the twist,” and whether viewers want more romance, more horror, or more pure psychological tension.

Reddit Theories: How Book 2 Might Translate On Screen

Without spoiling book twists, many readers fixate on one question: how the sequel will visualize what the book implies—especially around the locked-room dread, power imbalance, and the “who do you believe?” nature of Millie’s role in a rich household.

Reddit Debates: Trope Similarities, “Popcorn Thrillers,” and Why People Keep Reading

Some Reddit threads also debate genre DNA—what counts as a familiar domestic-thriller trope versus something more specific. For the film sequel, this matters because trailers often lean into recognizable “tells” (locked doors, house rules, unreliable smiles) while saving the real structural surprises for opening weekend.
