Key facts about the film at a glance.

What actually happened in A Simple Favor?

Plot summary

The film opens with mommy vlogger Stephanie (Anna Kendrick) giving an update about her glamorous friend Emily (Blake Lively), who disappeared five days after asking Stephanie to pick up her son from school (Digital Spy (entertainment news)). Stephanie begins investigating and uncovers that Emily is actually named Hope McLanden, a triplet whose sister Faith was an addict and another sister Charity died at birth.

The twist: Emily faked her own death by drowning her twin sister Faith at Squaw Lake Bible Camp in Michigan, then staged the accident to collect life insurance money and escape her criminal past. Emily killed Faith because Faith threatened to expose a childhood crime they committed together – patricide – unless Emily paid her $1 million (Wikipedia (film reference)).

Stephanie eventually exposes Emily by livestreaming the final confrontation from a hidden camera on her shirt. During the climax, Emily shoots Sean (Henry Golding) and is hit by a car driven by a school parent while escaping the police (Screen Rant (movie analysis)).

Key characters: Stephanie, Emily, Sean

• Stephanie – a widowed mommy vlogger who had a sexual relationship with her half-brother Chris (now deceased).
• Emily – a mysterious, sophisticated woman who is actually Hope McLanden, a triplet with a criminal past.
• Sean – Emily’s husband, a novelist who had an affair with Stephanie and was complicit in Emily’s fraud scheme.

The trio forms a love triangle that becomes a power game. Each character lies, and the audience is left sorting truth from performance.

Pros and cons

Did Blake Lively play her twin in A Simple Favor?

Behind the scenes

Yes, Blake Lively played both Emily and her twin sister Faith (also named Emily) through a combination of digital compositing, split-screen techniques, and physical performance (Wikipedia (film reference)). The twin is revealed as a key plot twist: Faith is Emily’s presumed-dead sister who was actually an addict and a victim of Emily’s scheme.

Director Paul Feig and the visual effects team shot Lively twice in the same frame, then merged the performances in post-production. The result is a seamless dual role that reinforces the film’s theme of identity theft and deception.

Use of CGI and visual effects

The scenes at Squaw Lake Bible Camp show both characters interacting simultaneously. Lively’s physical performance—different hair, posture, and accent for each sister—combined with post-production, made the twin reveal a technical achievement (Screen Rant (movie analysis)).

Why did Emily fake her death in A Simple Favor?

Motivation

Emily faked her death to escape her criminal past and start a new life with her son Nicky. She needed the life insurance money to fund her escape and to punish her husband Sean for his affair with Stephanie (Digital Spy (entertainment news)).

The fake death plan

Emily staged a drowning at Squaw Lake Bible Camp, using her twin sister Faith as the body. Faith’s addiction and threats to expose Emily’s patricide gave Emily motive to kill her and assume her identity. Emily manipulated Stephanie into helping frame Sean for the scheme by claiming it was his idea (Wikipedia (film reference)).

Who is the real villain in A Simple Favor?

Antagonist analysis

The film presents multiple candidates for the villain role. Emily is the most overt manipulator: she kills her twin, fakes her own death, and tries to frame Sean. But Stephanie also deceives—she lies about her past, manipulates Sean, and uses her vlog as a tool for justice that also serves her own need for attention (Screen Rant (movie analysis)).

Moral ambiguity

Sean is complicit in fraud and murder; he knew about Emily’s plan and benefited from the life insurance money. Emily’s twin Faith was a victim, but she also attempted blackmail. The film leaves the audience to decide who is most culpable. For a deeper dive into the film’s narrative complexities, explore this analysis of the AHS Staffel 10 Double Feature.

Summary

A Simple Favor succeeds as a stylish, twist-driven mystery that subverts suburban boredom with murder and deception. For viewers seeking a dark comedy thriller with strong performances and a memorable twin twist, the film delivers. The catch: its plot requires a willingness to accept coincidences and improbable schemes. For fans of the genre, this trade-off is worth it.
