Question: When Ben starts flipping through the book about the history of Derry, he begins seeing the same page being repeated several times. While this is happening, some children's voices can be heard singing. What exactly were they saying?
Question: Why is it that the gang never got eaten by the IT but every other child who encountered it did? I'm just looking for an in-depth answer like what where they doing right?
Answer: Well, for starters, fear evidently makes the children taste better. So screwing with them and holding off is almost like adding seasoning to meat. The way I took it as he eats the other children simply because he needs to eat, whereas he toys with the Losers' Club to have something better than just regular "food." They're like a dessert in a way. And I also kinda got the impression that Pennywise knew these kids were stronger, especially together, so he was also trying to wear them down more and weaken them.
Answer: It's because the kids were each together, were friends, and weren't scared of IT that they could defeat IT.
Question: While we see Henry Bowers and his gang get their comeuppance by the end of the film, why couldn't the same thing happen to the girls who bully Beverly?
Answer: According to the novel, it sleeps the entire time.
Answer: Sleep for 27 years.
Question: Was Pennywise the one who bombed the Ironworks in 1908, the one who killed the five Bradley folks in '35 and the one in the black spot in '62, or did he curse the people and the town to make them go crazy throughout the 27 years?
Answer: IT's malign influence makes the inhabitants of Derry particularly violent and vicious, culminating in an explosion of violence every 27 years. It's implied in the novel that IT sabotaged the machinery of the Kitchener Ironworks, though.
Question: Why does It not kill Henry?
Answer: "It" appears to know that Henry and his gang are "The Losers" antagonists and is using him as a weapon against them.
Question: Near the end of the movie, Beverly is captured by Pennywise. A few minutes later, Pennywise is making a weird dance: is that actually Bill Skarsgard dancing, or a stand-in dancer?
Answer: Bill Skarsgard did all his stunts.
Answer: Standin.
Question: Is there any real significance to the key around Beverly's neck that you see her wear throughout the film? I don't believe they ever really mentioned it and she is just seen fiddling with it a couple times. But she's never seen without it.
Answer: It's the key to her apartment. She wears it around her neck so she doesn't lose it.
Answer: They are singing a little rhyme called Oranges and Lemons.
