There’s Someone Inside Your House is a Netflix horror movie based on the YA novel by Stephanie Perkins. Shazam! writer Henry Gayden adapted the book and talks to Write On about tackling the horror genre and injecting it with emotion: "I've always liked slasher movies, but they've been my least favorite subgenre because you never really get emotionally invested in them… [Stephanie Perkins] comes from a YA romance background. [There's Someone Inside Your House] was her first horror book, so she created all these characters that were great, and I loved them, and there was a love story inside of this slasher book, and I really responded to it. And because I was emotionally invested, I suddenly wanted to write a slasher movie."   Henry goes on to give advice on taking your time developing a career: "I think a lot of people are in a rush to succeed right away when they're just not mature enough, mentally and also as a writer, to handle what you've gotta go through."   Don’t forget to subscribe to the Write On Podcast on iTunes!   Now available on Google Podcasts!
