The upcoming prequel “Welcome to Derry” is a follow-up to Andy Muscietti’s successful Stephen King movie adaptations “It” and “It Chapter Two.” These movies are about the town of Derry, which is visited every 27 years by Pennywise, a demon clown with supernatural origins who can take on different forms.

Pennywise thrives on fear, particularly of children, making him a formidable antagonist in the “It” series. While hints about Pennywise’s origins and motivations are scattered throughout Stephen King’s original novel and Muscietti’s films, much of his backstory remains shrouded in mystery. “Welcome to Derry” promises to delve deeper into Pennywise’s history and explore how his reign of terror impacts the town over an extended period.
