10The Movie Has No Narrator & The Story Is Mostly Told From Stephanie’s Perspective

The Book Switches From Stephanie’s To Emily’s To Sean’s POV

In Bell’sA Simple Favorbook, the story is told from three different perspectives: Stephanie’s, Emily’s, and Sean’s. Part 1 is told from Stephanie’s point of view through her blog posts. Part 2 then shifts to Emily’s perspective, which provides a lot of insight into her motives and fills in a ton of gaps in the narrative. Part 3 also offers some of Sean’s perspective. With all of these different accounts of the same events, the narration in the book is often unreliable.

There is no narrator in the film adaptation ofA Simple Favor,and aside from Emily’s descriptions of her own flashbacks and a few solo scenes between her and Sean in the present, the story is predominantlyseen through Stephanie’s eyes. The movie does contain some unreliable narration by having the character’s accounts contradict the same events depicted in flashbacks, but unlike the reader of the book, the viewer is always shown or told the whole truth.

7The Painting Is Different & Plays A Much Bigger Role In The Movie

There Is A Painting Of Twins In The Book Instead

In the book, Stephanie notices a painting of twins at Emily’s house, which Emily claims was painted by a famous artist. This painting was merely symbolic as it foreshadowed the eventual reveal that Emily had a secret twin sister.The film adaptation ofA Simple Favorchanged the painting to a nude portrait of Emilythat she claims was painted by an “almost famous” artist from the East Village who became obsessed with her. Emily stole the painting in hopes that it would one day be valuable enough to sell, but the painter never made it big.

Emily does have a secret twin sister in Bell’s novel, but the two of them never set their childhood home on fire to kill their father.

After she and her sister split up to avoid police detection, Hope McLanden moved to New York and eventually changed her name to Emily Nelson to make it harder for the authorities to find her.This is also why Emily does not like having her photo taken or posted on social media in the movie.

However, virtually none of this happens in the book. Emily does have a secret twin sister in Bell’s novel, but the two of them never set their childhood home on fire to kill their father.In the book, the twins' birth names are just Emily and Evelyn Nelson, not Hope and Faith McLanden. Since she was never running from the law, Emily never had to change her name.
