Being such a powerful being, Pennywise clearly sensed that the yellow coloring was unsettling to Georgie, so he changed his eyes to blue on the fly as a way to make Georgie associate him with family and safety.
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.
The character's eyes look in different directions, something that actually isn't a CGI effect. Bill Skarsgård did that 100% on his own – according to Andy Muschietti: “I told Bill, 'I want it in both directions, I want you to send your eyes looking away and give a really unsettling look'.
Bill Hader did not know that the effect of Pennywise's eye movement is not a digital effect, but that it is Bill Skarsgård himself who does it, since he has a lazy eye and if he relaxes the muscle his left eye can move in various directions Did you know this curiosity?
In the novel, It claims that its true name is Robert "Bob" Gray, but decided to be named “It”. Throughout the book, It is generally referred to as male, usually appearing as Pennywise. The Losers come to believe It may be female after seeing it in the form of a monstrous giant spider that lays eggs.
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.
They reach the conclusion that Pennywise has all of the adults under some sort of spell that prohibits them from seeing him. The adults of Derry are shown to be villainous in their own right as well. The adults of Derry are shown to be true villains of the story in the same way as Pennywise.
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 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.
It feasts on the flesh of humans simply because our fears are easy to manifest and they make us taste better. According to It, when humans got scared, "all the chemicals of fear flooded the body and salted the meat".
Being such a powerful being, Pennywise clearly sensed that the yellow coloring was unsettling to Georgie, so he changed his eyes to blue on the fly as a way to make Georgie associate him with family and safety. This made Georgie all the easier to lure in to his bloody demise.
Making Pennywise IT's go-to form wasn't a random decision from King, who initially envisioned the creature as a troll like the one in the story “Three Billy Goats Gruff”, but later changed it to a clown as he realized that children hate clowns more than trolls.
Pennywise the Clown is not a clown at all. The Pennywise the clown origin story sees an ancient, evil being that is perhaps as old as the universe itself. In the novel, however, the entity IT/Pennywise has a real name — Bob Gray. Bob Gray isn't human, however, and shares the same origin as IT.
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.
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.
If you want to get technical, It is an alien, but It's origin goes well beyond that. It is actually an ancient cosmic deity. A god of destruction, not just of our world, but of multiple worlds and even multiple universes.
It describes that it prefers to kill and devour children, not by nature, rather because children's fears are easier to interpret in a physical form and thus children are easier to fill with terror, which It says is akin to marinating the meat.
IT is a shape-shifting creature known as a Glamour who is billions of years old. Although it lived on planet Earth for many years, Pennywise originated in a void/dimension outside the regions of space known as the Macroverse.
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.
Pennywise targets children instead of adults because they are easier to scare and manipulate. Their fears are often simpler, more direct, and easier for Pennywise to exploit.
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.
Georgie Elmer Denbrough is a fictional character created by Stephen King from his 1986 epic horror novel It. Georgie is the younger brother of Bill Denbrough, and falls prey to Pennywise the Clown. He is used by Pennywise to taunt Bill throughout the novel.
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.
