● HBO reconstructs Stephen King's world with a new perspective and visual expression

Faithfully inheriting the worldview of the original author, Stephen King himself praised it, saying, 'It's wonderful. The first episode is terrifying.' Reconstructed under the executive production of the Muschietti siblings, this new chapter combines high drama and cinematic quality that will resonate with both horror fans and drama enthusiasts.

● Set 27 years before the film 'IT'. What happened in the era before Pennywise appeared?
