for the novel:
- Beam Me Up, Scotty!: A popular quotation from the book is "The only way out of the labyrinth of suffering is to forgive". This is never written or said word-for-word in the novel; however it is the central theme of Pudge's final essay.
- Creator Backlash: John Green is not fond of the book's cover, stating that it was supposed to have just the smoke and no candle, but people at bookstore chains complained that the smoke looked like cigarette smoke. When the book was re-released for its 10th anniversary, the candle was removed so just the smoke was visible, the way Green wanted it from the start.
- Troubled Production: Plagued the film adaptation of the book for the over 10 years since it originally came out (see main page).
- Write What You Know: The Culver Creek Preparatory School was closely based on the real life Indian Springs School (Birmingham, Alabama), a boarding school John Green attended. The Bufriedos were real, and they were even less healthy than the book made them sound.
for the TV series:
- Saved from Development Hell: The adaptation had been in Development Hell for damn near a decade. The long wait probably explains why there are many scenes from the book recreated very faithfully onscreen (although there is some considerable amount of Adaptation Deviation or Adaptation Expansion), as well as the fact that the series is set in the Turn of the Millennium (as the novel was).
