The first-look images released last year were tantalizing, but HBO’s eerie first teaser has solidified our ravenous desire for It: Welcome to Derry, a show we’d 100% drop into a sewer occupied by a demonic clown to watch.

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.
