Pennywise is one of modern horror’s greatest monsters
He’s the original killer clown from outer space and the most infamous villain in Stephen King’s bibliography, which is saying something. (All apologies, Randall Flagg.)  Pennywise the Dancing Clown is the form most frequently taken by a malevolent entity that’s been haunting the entire town of Derry, Maine for centuries; it’s lurked beneath the land since it hurtled through the cosmos and crash-landed on Earth from another dimension millennia ago. This shape-shifter can transform into its victims’ worst nightmares, feeding on both their fear and their flesh. Its preferred target: little kids, whose vivid imaginations give it an extensive menu of terrors to choose from. This also explains the monster’s default mode: What kid doesn’t love clowns? (At least before It more or less singlehandedly ruined their image, that is.)

But in addition to being one mean, multifaceted predator, Pennywise has exerted a malign influence on the entire town. He himself – or It Itself – only emerges from hibernation once every 27 years or so for a feeding frenzy that lasts roughly a year to 18 months. But Its presence in the sewers beneath Derry radiates an evil that makes the small town the murder capital of New England … and generates a sort of willful amnesia among the population. Such forgetfulness keeps folks from reflecting on their sleepy burg’s history of atrocities, disasters and mass murders. It also prevents people from connecting the dots when the creature resurfaces and kids start going missing en masse.

Overall, Pennywise combines a killer look and set of powers with one of King’s strongest concepts: a fairy-tale troll that hides out not under a bridge, but an entire city – a ghost that haunts not just one house, but all of them. As our foremost chronicler of small-town American evil, King has a royally good time with the idea.

I wrote a primer on It — the book, the miniseries, the movie, Pennywise, Tim Curry, That Scene, you name it — just in time for the release of the new blockbuster film adaptation for Rolling Stone.

This September, Lillis stars in director Andrés Muschietti’s highly anticipated adaptation of horror master Stephen King’s signature work, It. She plays Beverly Marsh, the sole female member of a close-knit gang of teen outcasts called the Loser’s Club. During one long, nightmarish summer, the Losers find themselves face to face with the child-murdering, shape-shifting entity that’s haunted their small town for centuries – a creature that most frequently takes the form of a sinister clown called Pennywise, played by Bill Skarsgård.

“We actually weren’t allowed to see him until our scenes, because we wanted the horror to be real,” Lillis recalls. “Everyone had different reactions, but all of us were like, ‘Wow, what did we get ourselves into?’ One look at him, and… you know, he’s a really scary clown that wants to kill us. I was a little bit shocked,” she laughs. “But then he went up to me afterwards and was like, ‘Hi, how’s things?’ He’s really nice, but I didn’t know how to react.”

Lillis had no such trouble connecting with her fellow Losers, who include Jaeden Lieberher as ringleader Bill Denbrough and Stranger Things’ Finn Wolfhard as class clown Richie Tozier. “I spent all my summer with them, so we got really close. We still keep in touch, send messages to each other.” That closeness helped Lillis connect with her own character. “I relate to Beverly – the way she deals with her emotions, and the way she was around the Losers. I felt that way around the actual actors.”

I wrote a little profile of Sophia Lillis, aka Beverly in the new IT movie, for Rolling Stone.
