Woman in the Window: Twist, Killer, Ending & Worth Watching

Here’s everything you need to know before pressing play, including the killer reveal, how critics received it, and whether it’s actually worth your two hours.

What is the twist in Woman in the Window?

The Woman in the Window operates on multiple layers of deception, and the first major reveal comes on Halloween night when Anna meets a woman claiming to be her neighbor Jane Russell. Anna notices something off — the reflection in a wine glass reveals this “Jane” is actually a mistress, not the real Jane Russell played by Julianne Moore. The film has four major twists that explode in the final third, according to Esquire’s analysis.

Key plot reveals

• The first twist uncovers Anna’s backstory: her husband and daughter died in a car crash she caused, explaining her reliance on wine and pills that distort her perception of reality (Esquire)
• The second twist exposes the woman Anna befriended as the real Jane Russell’s mistress rather than Jane herself (Den of Geek)
• The third reveal shows tenant David stabbed to death by Ethan after he identifies the mistress in a photo (Den of Geek)

The pattern here matters: each twist builds on Anna’s unreliability as a narrator, making viewers question whether what they’re seeing is real or filtered through trauma and substance abuse.

Neighbor family secrets

• Jane Russell is actually murdered by her own son Ethan (played by Fred Hechinger)
• Ethan is revealed as a serial killer who has killed before — including his birth mother (Esquire)
• Alistair Russell (Gary Oldman) remains silent throughout the confession while Jane confesses everything (Den of Geek)

Who is the killer in Woman in the Window?

Ethan Russell, the 15-year-old neighbor played by Fred Hechinger, is revealed as the film’s killer. What makes this particularly disturbing is that Ethan has been operating as a serial killer who murdered his own birth mother — Julianne Moore’s character — before the events of the film even begin.

Suspect breakdowns

• Ethan appears harmless initially, even friendly toward Anna
• His violent nature only emerges when threatened with exposure
• He kills tenant David after David identifies the mistress in a photograph (Den of Geek)

Final reveal

• Ethan delivers a post-murder speech revealing he has been targeting Anna specifically (Esquire)
• The final confrontation occurs on the rooftop using garden tools as weapons (Esquire)
• Anna pushes Ethan through a skylight, apparently killing him and overcoming her agoraphobia in the process (1428elm.com)

The implication: the film wants to have it both ways, presenting Anna as sympathetic while having her commit fatal violence, then wrapping it in a bow with a happy ending where she recovers in hospital with the Russells in custody.

Is The Woman in the Window worth watching?

This is where opinions split sharply. The film features a committed performance from Amy Adams and borrows heavily from Hitchcockian thriller traditions — but critics argue it fails to add anything meaningful to those influences.

Audience vs critics

The film draws comparisons to Rear Window, Gone Girl, and The Girl on the Train — but reviewers argue it lacks the watchability of those predecessors. Esquire describes the four twists as “a masterclass in joyfully terrible filmmaking” — meaning it succeeds as entertainment precisely because it’s so bad it’s entertaining.

The four twists in Netflix’s newest Amy Adams film make no sense, but it’s a masterclass in joyfully terrible filmmaking.

— Esquire Reviewer

Its twists are obvious; its characters are dull; it wants to be in the vein of a Hitchcockian thriller without really adding or commenting on.

Is The Woman in the Window Based on a true story?

No. The Woman in the Window is entirely fictional, adapted from A.J. Finn’s 2018 novel of the same name. The film shares its title similarity with a 1944 film starring Edward G. Robinson, but that’s where the connection ends.

Book adaptation details

• The source novel was published in 2018 under the author’s real name Daniel Hood
• Screenplay adapted by Tracy Letts (who also appears in the film)
• YouTube reviewers note the film differs significantly from the book’s ending (YouTube)

Fictional basis

• Anna Fox is an entirely fictional character created for the novel
• The agoraphobia and pill addiction are literary constructs, not based on real cases
• The Russell family secrets are invented plot devices

What this means: the film is a work of fiction marketed as a psychological thriller, not a retelling of actual events. Any online speculation about “true story” connections is unfounded.

What did critics say about Woman in the Window?

Critical reception split between amusement and frustration. The film borrows from Hitchcock’s voyeurism playbook but reviewers argue it lacks the craft to pull it off successfully.

Rotten Tomatoes consensus

While exact scores vary by publication and update, the general critical consensus leans negative. Reviewers consistently cite similar complaints: the twists feel manufactured, the characters lack depth, and the film strains credulity in its final act.

Common praises and criticisms

The praise-versus-criticism matrix below summarizes where critics and audiences align and diverge.

The pattern: films in this Hitchcockian tradition live or die on plausibility, and The Woman in the Window asks viewers to accept too many coincidences and contradictions for the payoff to land cleanly.

A lot of twists and turns that I myself had no clue were coming.
