- The actions of the children are not always entirely their own; they are often inspired by some sort of godlike being which they see as a "Turtle".
- One of the first chapters in the book is an elaborate gay bashing, where one of the gay characters is thrown into the Kenduskeag and eaten by Pennywise. This is adult timeline though, it won't be in the first movie.
- Ben's first encounter with Pennywise turning into a mummy is during heavy winter snowstorm; here, Pennywise is obviously unaffected by the weather.
- Beverly is introduced to Ben by Richie, and they are the three that head for the cinema. Afterwards, they have an extreme fight with the Bowers gang, after which Beverly belongs to the group.
- Bill, Richie and Mike are absent from the scene where Beverly shows the blood in her sink; so lots of interesting interaction between her, Ben, Eddie and Stan.
- Mike has two initial encounters with It; one in the form of a monstrous bird in an abandoned factory, a second one as Pennywise while playing in a brass band.
- Eddie's initial encounter with It is at the house at Neighbolt Street. He sees a syphillis infested hobo who offers him something obscene for money. Eddie returns there, climbs under the porch, and is assaulted by a horrendous version of the hobo named "the Leper". Some disgusting stuff going on here, as the half eaten person slowly turns to Pennywise and rolling out an enormous moldy tongue, offering sex to Eddie for free.
- Richie's initial encounter with It is with a giant plastic statue which tries to axe him and turning into Pennywise. Perhaps I do like the werewolf better.
- Stan's initial encounter with It is in an old watertower called the Standpipe. He is lured in there while birdwatching nearby, and two zombie kids who drowned there attack him in the dark.
- There are various violent encounters between Bowers or the Bowers gang and only one kid.
- Beverly spies one day on Bowers and gang, and follows the psycho Hockstetter, only to watch him being killed by It in the form of monstrous flying bloodsuckers. Beverly herself is also briefly under attack I think.
- There is a scene in which the children attempt to induce visions by means of a smoke hut. None of them endure except for Richie and Mike; they witness It crashlanding from space in prehistoric times.
- Richie and Bill enter the house at Neighbolt Street with a gun; Pennywise appears to Richie as a werewolf and chases them.
- All kids go together to attempt and kill it at Neighbolt Street before they even think of entering the sewers.
- Adult timeline; it is not Richie but Ben who visits the library. He witnesses a vampire with a mouth full of razorblades instead of teeth.
