Trivia / The Fault in Our Stars

  • Actor Allusion:
    • Posters for Nickelodeon are seen in the video game room. Natt Wolf had starred in The Naked Brothers Band, a Nickelodeon show. He's also singing lines from a song he and his brother Alex wrote during that scene.
    • Hazel is given a book to read called 'Counter Insurgence'. Shailene Woodley was due to star in The Divergent Series: Insurgent right after this film.
  • Actor-Shared Background: Willem Dafoe is an American with a Dutch surname, just like his character Peter van Houten.
  • Beam Me Up, Scotty!: Augustus never claims to feel kinship with Anne Frank because she died "of an illness" like his own. He and Hazel both clearly feel kinship with her because she died young, but the alleged murder-denying quote never occurs.
  • Breakaway Pop Hit: "Boom Clap" by Charli XCX. While the movie was hugely successful, the song is fast distancing itself from its origins as of this writing.
  • Breakthrough Hit: John Green has had many popular books before this, but this was his first massive hit and the book that really brought him into public eye. In 2014 alone, only the Divergent trilogy has been able to rival it in sales.
  • Career Resurrection: Nat Wolff faded into obscurity after The Naked Brothers Band finished its run, but this is now getting him even more attention than his old show.
  • Cast Incest: A strange Actor Allusion version with Shailene Woodley and Ansel Elgort. In Divergent they play siblings Beatrice and Caleb Prior. Here they play lovers Hazel and Augustus.
  • Casting Gag: Shailene Woodley and Ansel Elgort play a couple in this and siblings in Divergent. These two books/films also have a very large rivalry, alongside The Hunger Games.
  • Dawson Casting: Shailene Woodley was twenty three playing Hazel at sixteen. Ansel Elgort was borderline, being twenty and playing an eighteen-year-old (and amusingly is listed as nineteen at one point by Isaac).
  • Dyeing for Your Art:
    • Shailene Woodley had long blonde Rapunzel Hair, which she cut short to play Hazel. This affected The Divergent Series: Insurgent, where Tris cuts her hair drastically shorter than she does in the book - as Woodley didn't have time to grow it out again.
    • Lily Kenna, who played the young Hazel, had her hair shaved off on-screen.
  • Enforced Method Acting: Nat Wolff wore blackout contacts to properly simulate being blind.
  • Method Acting: Shailene Woodley learned how to shorten her breath to properly simulate how Hazel would speak in real life.
  • Shrug of God: John Green has had to do a lot of this to fans who want to know what happened to the characters before/after the contents of the book; this becomes somewhat humorous in light of the fact that there’s also a significant in-universe example where Hazel and Augustus ask Van Houten what happened to the characters of An Imperial Affliction and he tells them he doesn’t know.
  • Sleeper Hit: The film was adapted from a young-adult novel. Ever since The Hunger Games came out, other young-adult adaptations flopped, and it was expected to follow suit. It didn't, and proved to be a profitable film with a big $50 million opening and helped strongly boost sales. It's saying something when an action movie starring one of the most bankable actors of all time flopped just by going against it.
  • Star-Making Role: For Ansel Elgort. Divergent also got him attention, but this is the film that shot him to the stratosphere.
  • What Could Have Been:
    • The original ending had Hazel and Van Houten try to find a way to honor Gus's death by dying themselves in a way that would accomplish something and was meaningful to his life. They plan to go out and kill a drug lord and die at the hands of his bodyguards, but apparently decide against the idea before the story's conclusion. One editor, upon reading this ending, remarked, "I can't tell if the last 40 pages are a joke." The again, neither can John Green himself.
    • Originally, the story was going to be from Isaac's point of view.
    • The scenes in Amsterdam were intended to be shot on location. However, filmmakers were intimidated by the poor October weather - and also denied permission to film inside the Anne Frank House. As a result, a replica was built, and Pennsylvania doubled for Amsterdam.
    • Mae Whitman was John Green's preferred actress to play Hazel. Nonetheless, he was blown away by Shailene Woodley's audition and gave her the Approval of God.
    • A scene was filmed featuring an argument between Gus and his mother right before the trip to Amsterdam, that also features in the book. It would have acted as Foreshadowing that Gus's cancer has come back.
  • Write Who You Know: Hazel is based on a girl John Green met at a Harry Potter convention, when he noticed her carrying an oxygen tank. He came to like her through various vlogs she put online, and they exchanged emails - much like Hazel and Gus do with Peter. The girl's middle name was Grace, like Hazel's. They remained good friends until her death in 2010.
