Stephen King's It (1990)

Things are not right in the small American town of Derry: half a dozen children have been murdered or are untraceable. “It” – evil – is once again playing its bloody game in the form of the clown Pennywise, just like it did thirty years ago. Seven teenage friends, known as the “Losers Club” and all of them ridiculed outsiders, were only able to defeat him because they remembered their common strength and used supernatural powers. Only one of them remained in Derry: librarian Mike Hanlon. He brings the group back together to fulfill an old vow. Deep down in the sewer labyrinth, the men once again face their fear of horror personified.
