It adaptations: books, films & series
Every version of It — the books, films & series, compared across media.
An ancient evil haunts the town of Derry, Maine — one that preys on children, taking the shape of a clown called Pennywise. Stephen King's It introduced seven outcast kids whose friendship becomes the only weapon against something older than memory. That premise has drawn storytellers across decades and media: a landmark novel, two theatrical films, and two TV productions all return to Derry to explore what it means to face terror together.

Frequently asked
Is It based on a book?
Yes. All screen versions trace back to Stephen King's novel It, which follows seven children terrorized by a shape-shifting evil entity in the town of Derry, Maine.
How many versions of It are there?
There are five versions across three media: the original novel It, two theatrical films (It and It Chapter Two), and two TV productions (It from 1990 and IT: Welcome to Derry from 2025).
Which It adaptation should I start with?
If you prefer films, It (2017) covers the Losers' childhood chapter and pairs naturally with It Chapter Two. If you want both timelines in one sitting, It (1990) covers childhood and the adult reunion as a single story.
