That's why there are meaningful moments in the movie where The Turtle is present -- mainly that scene in the quarry where the kids bond together for the first time, including Beverly. They go into the water, and one of them says, "Oh, it's a turtle!" And they go and splash underwater, and the screen goes completely green, and I think people sort of brace because they think something scary is going to happen, but then we cut to the next scene. It's a bit of an Easter egg for people who've read the book. For people who don't know the story at all, The Turtle goes completely unnoticed, I think. But I didn't want to leave The Turtle completely out, because I think it's a hint for further exploration in the second part.
There's a lot going on with the kids' T-shirts too. Richie has a shirt that says Freese's, which is Derry's department store. In the book, there's a whole sequence that describes how Richie is chased by Henry Bowers and his gang, and he saves his life by hiding in the aisles of Freese's. There are a few other references, like the bicycle shop and the Tracker Brothers, that appear too. The Tracker Brothers are a company in Derry -- a trucking company but they also have a baseball diamond where all the kids get together and play. The thing with such a rich, big book is you have to pick your events because you have to make a two-hour movie, but you have the instinct of wanting to put in a little more. As long as you have T-shirts, you can do that [laughs].
