So I am not entirely sure why this movie is being called "Chapter 2" because unless there is some serious editing or a big plan I am not aware of, there isn't going to be any other chapters after this. When Stephen King wrote the book, there was a time involving kids and a time when the kids grew up to fight Pennywise again. Because they didn't do a good enough job killing him as children. That was the story. So putting it in chapters seems funny.
This new trailer is longer than usual. We get a nice long look at an iconic scene from the book. Beverly Marsh visits her old home upon returning to Derry. There is an old woman who lives there and invites her in. Long story short, the old woman is Pennywise in disguise, in the books Beverly was afraid of the old witch from Hansel and Gretel and her old home eventually begins to look like the sweet house from the book. Also, in the book, the tea she drinks is actually shit. Literal shit. Because you know, Pennywise lives in the sewers and all. In the trailer, Bev makes a strange face after taking a sip of the tea, so I wonder if they left the shit in the movie?
The trailer is very affective and I am curious to see how they end it. According to interviews, tons of iconic stuff from the book is getting put into this new movie and I think fans are going to be blown away by what they are about to see.
