'It Ends with Us' trailer:Blake Lively falls in love in Colleen Hoover novel adaptation

"It Ends With Us" is the first film adapted from the novels of Hoover. The book sold more than 4 million copies as of 2022, though it has received criticism from some who argue the book romanticizes abuse. A sequel, "It Starts with Us," was published in 2022 and sold over 800,000 copies on its first day. The best-selling 2016 book was inspired by Hoover's mother and her experiences in an abusive relationship with the author's father.

Unlike the book, where Lily is 23 and Ryle 30, both characters in the film are in their mid-30s. Baldoni and Hoover recently defended aging up the characters, saying it would naturally take a long time for Ryle to become a prominent board-certified neurosurgeon. They also wanted Lily to be someone with life experience, who is comfortable and confident in herself by the time she meets Ryle.

Here's a look at the lead cast of "This Ends with Us."

Book vs. movie:All the major changes between the book and Blake Lively movie

Blake Lively as Lily Bloom

The film's titular character, Lily Bloom, is ironically a florist, who recently moved to Boston from her hometown in New England to finally fulfill her dream of opening a flower shop. She is described as "a woman who overcomes a traumatic childhood to start a new life and chase a lifelong dream."

“Lily is not a wilting lily,” says Lively about her character in the film's production notes. “She has both feet on the ground and her head screwed on tight—she has real spice and agency. But you can be a woman with confidence and agency and know better, and still not see all of the red flags that you should."

Justin Baldoni as Ryle Kincaid

Ryle Kincaid, a charming neurosurgeon, is one of Lily's love interests. The two share a passionate connection and as they "fall deeply in love, Lily begins to see sides of Ryle that remind her of her parents’ relationship," says the Sony Pictures about Ryle.

In the book's official synopsis, Ryle is described as "assertive, stubborn, maybe even a little arrogant," but also someone who is "sensitive, brilliant, and has a total soft spot for Lily."

Baldoni said he wanted to portray Ryle "as a complex, smart man who has never dealt with old traumas," adding the character "may not be exactly (be) what viewers expect” and that he does not want to glorify him in any way.

Brandon Sklenar as Atlas Corrigan

Atlas is Lily's high school sweetheart, who suddenly reappears when she's with Ryle putting her relationship into jeopardy.

“Atlas and Ryle are polar opposites,” Sklenar says about his character. “Ryle has a manipulative, toxic presence. Atlas is strong and sturdy, an example of what masculinity can be in a calm, present and open way. Unlike Ryle, he has no need for validation. When he’s with Lily, he’s just purely there for her.”

Isabela Ferrer as Young Lily Bloom

Ferrer described young Lily as a shy introvert, but someone with "a lot of strength from the start."

Alex Neustaedter as Young Atlas Corrigan

Jenny Slate as Allysa

Lily's second friend in the city, Allysa, who is also Ryle's sister, is described as an "outgoing fashionista."

“Allysa isn’t apologetic about being herself,” says Slate about her character. “She’s decked out in designer clothes. She goes after what she wants. But as soon as she makes that connection with Lily, she reveals this huge, loving heart. She shows Lily what it means to show up for someone you love, no matter what.”

Hasan Minaj as Marshall

Marshall is Allysa’s exuberant and eccentric husband. Minhaj, in the film's production notes said he came up with a backstory for his character.

“Marshall is a tech entrepreneur, and he sold his company for a pretty big nine-figure sum,” Minhaj says. “That’s the energy and swagger that I’m putting into the character. Marshall and Allysa are quite…how should I say it? Extra? Marshall’s definitely flirting with a billion dollars, but he’s not quite a billionaire, so he’s overcompensating.”

Amy Morton as Jenny

Jenny is Lily's mother and a significant person in her life.

"Jenny lives with a very complicated cocktail of emotions, but that shared experience is ultimately what helps her, and Lily heal together," Morton says of her character.
