The Fault in Our Stars: 5 Differences Between the Book and the Movie

To say that the expectations for the The Fault in our Stars film adaptation were sky-high would be a gargantuan understatement. Since its release in January 2012, John Green’s young adult novel of star-crossed cancer-ridden lovers Hazel and Augustus has skyrocketed to the top of the New York Times bestseller list and remained on the prestigious list for an astonishing 100-plus weeks. People of all ages were and continue to be drawn to the very relatable story of young love, supportive friendships and the very definitions and scope of family in a crisis. At its core it also emphasized the Dead Poets Society mantra of carpe diem and to never abandon one’s passion and thirst for literature and sharing it with others. Much like central heroine Hazel Grace Lancaster instantly shared her favorite book ‘An Imperial Affliction’ with her soul mate Augustus Waters, so too did millions of people share The Fault in our Stars with their loved ones.

While author John Green was regularly on the set of the film to ensure that it stayed true to his celebrated book, there were a few key differences. The following are five of the most noticeable ones (WARNING: there are spoilers ahead).

1. How Hazel and Augustus meet
In the book Hazel is in the room in which the Support Group takes place (“the heart of Jesus”) and is pouring herself a drink when she notices that a seated boy is watching her. He keeps staring at her as she takes her place next to her close friend Isaac and waits for group leader Patrick to begin the proceedings. In the movie, their meet-cute is far more movie-like. As Hazel is about to take the stairs to the Support Group, she quite literally bumps into Augustus, and they warmly smile at each other as their bodies momentarily graze.

“I grabbed a cookie and poured some lemonade into a Dixie cup and then turned around. A boy was staring at me. I was quite sure I’d never seen him before. Long and leanly muscular, he dwarfed the molded plastic elementary school chair he was sitting in.”


2. Isaac

In the book Isaac is a close friend of Hazel’s from Support Group who she shares sighs with regularly during the span of the group sessions. Physically he is described as having blond hair and wears thick glasses until his eye surgery later in the book. Immediately following his surgery she even visits him in the hospital and they maintain a close connection throughout the book. In the movie it is implied that he is Augustus’ friend and not very close with Hazel (although she does impart advice to him after his breakup with former girlfriend Monica and maintains the same talk with him following Augustus’ funeral). Physically he is played by average build, short brown-haired Nat Wolff, who portrays the character as a McLovin’-esque goofball.

“The only redeeming facet of Support Group was this kid named Isaac, a long-faced, skinny guy with straight blond hair swept over one eye.”

“Isaac and I communicated almost exclusively through sighs.”


3. Hazel’s life outside of Augustus

In the book Hazel has a close friendship with a girl named Kaitlyn who she confides in about Augustus. Hazel is also described as a vegetarian who regularly attends college classes such as American Literature, Poetry and Algebra. In the movie her Mother appears to be her only confidante and her classes are glossed over and only briefly mentioned in her conversation in the beginning of the film with Augustus in his swerving car.

“My class was American Literature, a lecture about Frederick Douglass in a mostly empty auditorium, and it was incredibly difficult to stay awake. Forty minutes into the ninety-minute class, Kaitlyn texted me back.” 


4. Hazel and Augustus’ respective families

In the book, Hazel has a very tight knit relationship with both of her parents as well as Augustus’ parents. So, too, does Augustus have a close friendship with Hazel’s parents and his own. In addition, he has a number of sisters who are mentioned in a few portions of the book. In the movie, however, while Hazel’s father is shown to be a warm caregiver, he seems to be on the outskirts of the key events. When he speaks to Hazel after Augustus’ funeral and knowingly states, “it was sure a privilege to love him, huh?”, the line doesn’t resonate as much as it should as he’s shown barely speaking to Augustus in the movie. Sadly Augustus’ parents barely have any screen time as well and it is unclear when Hazel would have bonded with them.


5. The Ending

In the book, Hazel receives an email from Peter Van Houten’s assistant Lidewij with the correspondences the dying Augustus had with Van Houten. Within the email’s attachments are Augustus’ heartfelt pleas for Van Houten to polish and edit his eulogy for Hazel. In the movie, Van Houten hands Hazel the piece of paper with Augustus’ pleas to him and her voiceover of this letter closes the film.

“Lidewij finally wrote back just after six P.M. while I was on the couch watching both TV and videos on my laptop. I saw immediately there were four attachments to the email and I wanted to open them first, but I resisted temptation and read the email.” 

“Okay, maybe I’m not such a shitty writer, But I can’t pull my ideas together, Van Houten. My thoughts are stars I can’t fathom into constellations.”


Despite the liberties the screenwriter took with modifying the cherished book, The Fault in our Stars movie adaptation will resonate with fans of the book as well as unfamiliar to the source material viewers. The movie ensures that the timeless story of Hazel and Augustus will live on in the hearts and minds of viewers of all ages.
