It's the story that's been blamed for fuelling the Western world's widespread fear and mistrust of clowns - and now, the new trailer for the 2017 adaptation is set to stoke that phobia even further.
It, originally a 1986 horror novel by Stephen King, was adapted as a TV miniseries starring Tim Curry in 1990, but since then the tale has remained dormant - until now.
Under the direction of Argentine horror director Andres Muschietti, the new film - which will be split into two parts, with the first coming out this September - looks to be even scarier than the first trailer suggested.
The second trailer ramps up the horror even more than the one released in March, with Benjamin Wallfisch's chilling soundtrack and Bill Skarsgard's unnerving depiction of Pennywise the sewer-dwelling, shapeshifting clown creating palpable tension.
The new trailer reveals a little more of the storyline than the last, showing that the group of boys terrorised by the dark, brooding force embodied by the clown band together to beat it.
The second It trailer also features a number of frights - one that features a truly insidious room packed with clown dolls that one of the boys is lured into by Pennywise, who fans finally get a few proper look at.
Skarsgard's youthful, handsome look creates a Pennywise that is quite different to Curry's iconic depiction, with his casting raising a few eyebrows for that very reason - but he said it's important he brought something different to the role.
"It's important that we do something fresh and original for this one. It's purposely not going toward that weird, greasy look," he told Entertainment Weekly.
It will be released in New Zealand cinemas on September 7.
