Fans familiar with King’s work will already know that the show features Dick Hallorann (Chris Chalk), who later becomes the chef at the Overlook Hotel from The Shining, where he meets Danny Torrance and recognizes that the young boy has psychic abilities.

The teaser footage from It: Welcome to Derry Episode 3 explicitly mentions that the military is aware of Hallorann’s abilities and are using them to try find the entity that calls itself Pennywise. However, the trailer also makes a reference to The Shawshank Redemption.

It shows Hank Grogan (Stephen Rider) in jail because the police suspect the projectionist is the one responsible for killing the kids in the wildly gory theater massacre at the end of the first episode. Chief Bowers (Peter Outerbridge) tells him, “Do you know what they do to kiddie killers in Shawshank?” which is an obvious reference to the titular prison from The Shawshank Redemption.

Interestingly, Bowers is also a reference to Muschietti’s IT movies, because he’s the grandfather of Henry Bowers, the bully who frequently attacks the Losers Club and eventually becomes Pennywise’s pawn. Clearly It: Welcome to Derry Episode 3 isn’t trying to hide its wider connections to King’s universe.

For now, fans are celebrating the new teaser and the show itself, with one writing, “It’s my very first time watching a horror… It’s really good and scary, I’m glad there is no hideous gore.”

“The first two episodes were so good, but this one looks absolutely PHENOMENAL,” said another, while a third quipped, “This episode will shine.”
