Stephen King's iconic horror narrative, "It," returns to the screen with the HBO Max prequel series, "IT: Welcome to Derry," which plunges viewers into the cursed town of Derry, Maine, in 1962. This series serves as a direct prequel to Andy Muschietti's critically acclaimed "It" films from the 2010s, with Muschietti and his sister Barbara returning as co-creators and executive producers. The show aims to explore the deeper lore and origins of the malevolent entity Pennywise the Clown, set 25 years before the events of "It: Chapter One," and is planned for a three-season arc that will delve into Pennywise's previous cycles in 1962, 1935, and 1908, drawing inspiration from the hidden stories and "crumbs" within King's original 1986 novel.

The premiere episode, titled "The Pilot," immediately establishes the series' dark and brutal tone. It opens with 11-year-old Matty (Miles Ekhardt), a troubled child with a pacifier, who attempts to hitchhike out of Derry on a snowy Christmas night. He is picked up by a seemingly friendly family, but their demeanor quickly turns bizarre. As they repeatedly pass the "Welcome to Derry" sign, suggesting they are trapped in a loop, the pregnant mother goes into a horrific labor, chanting "O-U-T! O-U-T!" alongside her family. What emerges from her is a grotesque, two-headed, bat-winged demon infant, still attached by its umbilical cord, which violently attacks Matty, leaving his fate ambiguous but implicitly fatal.

Four months later, in April 1962, the narrative introduces new characters, including Major Leroy Hanlon (Jovan Adepo) and Captain Pauly Russo (Rudy Mancuso) arriving at Derry Air Force Base. Hanlon, a Black man, quickly faces disrespect and racist undertones, highlighting Derry's dark history of racism, a theme the series intends to bring to the forefront as a reflection of societal injustices, portraying "man-made" evil as equally significant as the supernatural horror. Concurrently, a group of high school friends, Lilly (Clara Stack), Marge (Matilda Lawler), Phil (Jack Molloy Legault), and Teddy (Mikkal Karim Fidler), are grappling with Matty's disappearance. Lilly, who shares a past memory with Matty in an abandoned observation tower, starts hearing his voice singing from her bathtub drain, while Teddy experiences a terrifying encounter where Matty's face appears in his lamp shade.

The friends, joined by Phil's younger sister Susie (Matilda Legault) and Ronnie (Amanda Christine), the daughter of the local movie theater owner, decide to investigate Matty's whereabouts. Their search leads them to the local library, where they find an article about Matty's disappearance, and then to Ronnie, who admits to also hearing unsettling voices in the movie theater. Meanwhile, Major Hanlon is assaulted by masked figures demanding classified information, from which Pauly Russo helps him escape.

The climax of "The Pilot" unfolds when the children gather at the deserted movie theater to watch a print of "The Music Man," which Matty had been singing. Matty mysteriously appears on the screen, looking demented and holding the same winged demon baby. He blames his friends for his predicament, and the creature dramatically emerges from the screen, initiating a brutal attack. In a shocking departure from previous "It" adaptations where victims were typically killed individually, the demon baby swiftly and gruesomely kills Teddy and little Susie. Lilly and Ronnie barely escape, with Lilly screaming in horror as she realizes she is still clutching Susie's dismembered hand. This unexpected mass slaughter of child protagonists subverts audience expectations, sending a clear message that "nobody is safe" in this iteration of Derry, making the series' future highly unpredictable.

The creation of these horrifying scenes involved a seamless blend of practical effects and cutting-edge visual effects. VFX supervisor Daryl Sawchuk and prosthetics department head Sean Sansom, both veterans of the "It" films, collaborated closely. The opening birthing sequence, for instance, utilized a practical birthing rig, prosthetic legs for the actress, real goo and blood, and a practical puppet for the fetal demon baby, which was also digitally enhanced. Confined spaces like the car interior presented challenges, requiring innovative techniques for puppeteering and actor interaction. The practical elements were crucial not only for the visceral visual impact but also for providing tangible references for lighting and allowing the young cast to deliver more believable and visceral performances, demonstrating a respectful homage to old-school horror techniques enhanced by modern technology. With seven more episodes and two additional seasons planned, "IT: Welcome to Derry" promises an intensely graphic and unpredictable journey into the origins of Pennywise and the pervasive evil infecting the town.
