It: Welcome to Derry, the prequel TV show for Stephen King’s It, has a new trailer. Coming to HBO Max (née Max, née HBO Go, née HBO Now, née…) this fall, the show centers on what seems to be the origins of It’s supernatural villain Pennywise the Clown and the first crop of kids to ever take him down.

Stephen King's iconic clown demon Pennywise stalks a Maine town during the 1960s in "It: Welcome to Derry," an "It" prequel series on HBO.

"Get ready to go back to where IT all began..." reads HBO's tagline, suggesting It: Welcome to Derry presents the morbid origin story of Pennywise. Set in the 1960s, the plot centres on a group of young people exploring the mystery of an evil force that has been terrorising the town of Derry for centuries.
