After the debut of the first season, IT: Welcome to Derry confirms itself as a much more ambitious project than a simple prequel series. In a recent interview, Andy Muschietti clarified that the story was conceived from the beginning as a multi-season narrative, with an arc that could extend at least to a third season. The idea is to explore Derry going further back in time, showing the cycles of Pennywise's awakening and the tragedies that marked the city before the events of IT and IT – Chapter Two.

The second season, not yet officially confirmed by HBO but already outlined creatively, should be set in 1935, during the Great Depression. At the center of the plot would be the massacre of the Bradley Gang, one of the darkest episodes cited in Stephen King's novel, with Derry becoming the stage for collective violence and hysteria. According to Muschietti, each season will have its own historical and narrative identity, but will always be linked to the cyclical and "timeless" nature of the entity hidden beneath the city.

The long-term plan then includes a third season set even earlier, in 1908, with the explosion of the Kitchener Ironworks as a possible central event. A disaster that, in the original material, represents one of the key moments in Derry's past and one of the most evident signs of Pennywise's influence on the community. The goal is not only to show new horrors but to tell how evil takes root over time, passing from generation to generation.

For now, there are many uncertainties: HBO has not officially announced the renewal, there are no release dates nor details about the future cast. However, Andy Muschietti's statements and the reception of the first season suggest that IT: Welcome to Derry could become a true horror fresco on the cursed history of Derry, expanding the cinematic universe of IT in a coherent and unsettling way.
