It Chapter 1 & 2: Every Monster Explained & Ranked
18. The Richie Doll
In one of the most memorable sequences of the first movie, Richie ends up being cut off from the rest of the Losers in a room full of clown dolls - one of his ultimate fears. Because he's normal and clown dolls are horrifying.
He walks through the room full of grotesque mannequins and marionettes - which themselves are pretty terrifying - with some of the dolls moving slightly as he walks by. At one point there's a doll based on Tim Curry's Pennywise, in a nice touch, but the climax of the scene sees Richie come upon a coffin.
Inside, in a slightly weird revelation, is a puppet version of Richie infested with maggots. It makes very little sense, but for a creepy moment it works and it leads to a good jump scare when Richie closes the casket and Pennywise bursts out.
