“Something bad’s coming…” HBO Max has finally unveiled the creepy full official trailer for IT: Welcome to Derry, a brand new horror spin-off series based on the two IT movies from 2017 & 2019. This has been in development for years, finally debuting for streaming starting in October – just in time for horror season. This prequel series about Pennywise the Clown is set back in the 1960s, leading up to the events of the first movie. The director of the movies, Andy Muschietti, developed this with his sister, Barbara Muschietti. IT: Welcome to Derry stars Taylour Paige, Jovan Adepo, Chris Chalk, James Remar, Stephen Rider, Madeleine Stowe, Rudy Mancuso, and Bill Skarsgård returning to his role. This trailer shows more of what’s going on in this town – stories involving kids and the military and a disappearance. And eventually the arrival of the alien creature that becomes Pennywise. They’re playing this as the Origins of Pennywise the Clown series. As expected, this has tons of scary shots – especially in the final 20 seconds. Watch out. 🎈

Here’s the main official trailer (+ posters) for HBO Max’s series IT: Welcome to Derry, from YouTube:
