In the novel, It is a shapeshifting monster who usually takes the form of Pennywise the Dancing Clown, originating in a void containing and surrounding the Universe—a place referred to in the novel as the "Macroverse".
It is believed that IT's real desire is to consume all life on a planet, leaving it barren when the creature moves on. The being doesn't have to just eat humans, too, but it is the preferred sustenance of IT, especially when they are fearful as the terror provides extra flavor.
In the novel, It's origins are nebulous. He took the form of a clown most frequently, Mr. Bob Gray or Pennywise, but his true form is an ancient eldritch entity from another universe who landed in the town that would become Derry by way of an asteroid and first awoke in 1715.
King decided for IT to predominantly take the shape of Pennywise the Dancing Clown because he believes "clowns scare children more than anything else in the world." IT influences the adults of Derry to passively ignore it and not interfere with his attacks on Derry's children.
Stephen King's IT introduced readers to a one-of-a-kind creature that can take any form, the most common one being Pennywise the Dancing Clown, and as menacing as it is, this creature has one big enemy it's truly scared of: Maturin, the turtle.
In their final battle, the Losers' Club was able to kill Pennywise by reducing him to a child-like form as they overcame their fears. In the moments before Pennywise died, his fear is reminiscent of Georgie's own, therefore closing the cyclical nature of Pennywise's murders. Georgie's death was unique in It.
Did you notice something off about Pennywise's eyes in IT? Other than just being really creepy, they actually change color going from yellow to blue. But why does he do that? He changes them to blue in order to lure Georgie.
Pennywise offers Georgie his boat back, but when Georgie attempts to reach out to it, Pennywise grabs Georgie's arm and bites it off, leaving Georgie to bleed to death in the rain.
[Stephen King's IT] Why doesn't Pennywise go after adults the way he goes after kids? Pennywise's deal is that he strikes fear into the hearts of others before devouring them, as essentially fattening them up before he feasts.
Kersh tells Beverly she's the daughter of a carnival worker who happens to look just like Pennywise. As explained in Stephen King's IT, this man is Bob Gray — and IT, that pesky inter-dimensional force of evil, stole his likeness. For 85-year-old Gregson, the character of Mrs. Kersh was initially even more mystifying.
IT arrived on Earth through an event similar to an asteroid impact, landing in what would later become Derry, Maine. Once there, IT adopted its usual pattern of hibernation that lasted between 27 and 30 years, awakening to kill and eat and then going back to sleep.
Martin Morgan Pennwise is (biologically) asexual and has the ability to reproduce. Therefore even though King describes pennywise as a female further into the book, 'IT' is (technically) neither male nor female.
Throughout Stephen King's It, Pennywise is referred to as a male, but author Stephen King pulled a fast one on readers in the It book ending by revealing the creature's true form was a pregnant spider, implying that it is, in fact, biologically female.
IT (2017)- Pennywise is seeing drooling many times throughout the movie. This was not an effect. Bill Skarsgård had to have prosthetic teeth in that made him drool excessively in many scenes.
One of Pennywise's most recognizable features though is his ridiculously large head. My theory is that he's got such a big head because when he first came up with his Pennywise shape, he was basing his appearance on the humans that he had spent most of his time with: infants.
In It (2017), Pennywise changes the colour of his eyes from yellow to blue, which are the same colour as Bill's, to lure Georgie. "There were yellow eyes in there: the sort of eyes he had always imagined but never actually seen down in the basement.
Answer and Explanation: No, Stephen King's It is not based on a true story. King had the idea for It when looking at an old wooden walking bridge in 1978 near his home in Boulder, Colorado.
The novel explains that IT landed on Earth during an asteroid impact and established itself under the land Derry would be later built on, and initially preyed on indigenous tribes. From that point of view, IT/Pennywise would be billions of years old, but his clown shape wouldn't be that old.
Pennywise's murders are cyclical; every 27 years, he returns to kill the children of Derry. This cycle is finally completed and forever closed when Pennywise is killed.
In both the book and the films, It is an ancient alien creature, older than civilization, and in King's novel, older than our universe. It feasts on the flesh of humans simply because our fears are easy to manifest and they make us taste better.
But, the film makes clear, It (sometimes written as “IT”) isn't just a clown. Oh no. As detailed in King's novel, he's an ancient, cosmic being, described in the novel as an “Eater of Worlds”, who is able to adopt a variety of nasty guises.
