10 Things You'll Only Notice in the It Remake If You Read the Book

In the film, Mike has lost his parents in a terrible fire. He even describes his horrifying memory of watching them burn alive. The book actually has a very similar event that ties into the town of Derry's dark history. One of It's feeding cycles comes with the burning of the Black Spot. The Black Spot was a bar that was frequented by a large quantity of black soldiers from a nearby army base. In the books, a group of white supremacists locks all the patrons inside and burns the building to the ground. So, basically, Mike's tweaked story in the film co-opts that event.
