I think 13 Reasons Why will always be an important part of my life. It was the first job I ever had, even if it’s in a small capacity, on social media.

What happened to Hannah will always be the first clause of the story. The rest of the story is about young people, as so many young people, maybe all young people today (learn) how to heal from the things that have hurt them…to make the world that they want it to be, not just the world they are inheriting…and above all, how to take care of each other.

  • Katherine Langford, the actress who portrays Hannah Baker, admitted that she hadn't read the book before starting filming, not knowing what she was in for and hadn't read it during filming and then realized that the story was getting quite heavy. Dylan Minnette, the actor who portrays Clay Jensen, also admitted he hadn't read the book before filming.[9]
  • Selena Gomez commented in the 2017 13 Reasons Why panel, that she felt like the book was meant to become or be a series.[9]
    • Mandy Teefey, Gomez's Mother, also commented that she read the book and also felt like it was meant to become or be a series.[9]
  • Selena Gomez was originally asked to be cast as Hannah Baker, but she stated that she didn't want there to be two different conversations: one about the Netflix series and the other focused on her. She asked for someone else to be cast to take the focus off of her. She felt the series needed to do the book justice for the young adults who related to the story line.

  • The second season is not based on the book.
