Often hailed as his scariest fiction, the story has been adapted before for the small screen in a double episode feature, but it wasn't until previous year that it made its way to cinemas across the globe, making the franchise's Pennywise a true global horror icon.
One person who might not be looking forward to the sequel is Bill Skarsgard, the actor who portrays Pennywise in the reboot.
When he was done with the role, he said the moment he realised he was done with Pennywise was like "an exorcism", but revealed how the clown still visited him in "very odd and vivid Pennywise dreams", where the entity would take on a number of different forms. "I liken every character that I do to a relationship that you are in. It was in the shape of either me dealing with him, sort of Pennywise as a separate entity of me, and then also me as Pennywise in circumstances that I didn't appreciate".
Though Pennywise managed to scare millions of viewers, the assumption from the majority would be that Skarsgard would be immune to his fear, but just like most other people, the clown managed to work his way into the young actor's psyche.
"I was home, done with the movie, and I started having very unusual and vivid Pennywise dreams. Every night, he came and visited", he said. "It's just like being in a very destructive relationship", Skarsgard adds.
Explaining the meaning of his dreams, the actor said that "this was a process of letting go of the monster". "People don't really realize it until they're out of it". The sequel will pick up 27 years later after the first film and is scheduled to be released in the USA on September 6, 2019.
