Question: In the scene at the rock pile when the book comes to life and Pennywise says, "I'll kill you all. I'll drive you crazy and I'll kill you all", these words don't at all match whatever words his mouth is actually forming. It's so obvious. This is an audio dub to replace whatever he's supposed to be saying in the book. Does anybody have any idea what happened here?
Question: Was there only one It? If It/Pennywise, was an alien or something, how come there wasn't more of them?
Question: Pennywise, the Singing and Dancing clown, is dressed in bright colors in the movie. The clown in the book wore silver. Does anyone know why this change was made?
