First Trailer For 'It' Is Here, So Get Ready To Have Clown Nightmares

If you want to feel legitimately terrified for the rest of the day, then you're in luck, because the first trailer for the "It" film is here.

Many are already familiar with Stephen King's classic 1986 horror novel about a demonic clown, thanks in large part the ABC television miniseries adaptation from 1990.

But this new film from director Andrés Muschietti will be the first time "It" has been on the big screen.

And it's clear they're trying to do the source material justice — because this trailer is scary AF.

At first, you might think, "Oh, this is a cute movie about a loving relationship between brothers."

But then, NOPE. True to the original, it's about finding terrifying clowns in sewers.

And seeing creepy floating red balloons everywhere!

The setting has been updated from the '50s to the '80s, giving this trailer a "Stranger Things" vibe.

Well, that, and the fact that Mike from "Stranger Things" is literally in the trailer.

Actor Finn Wolfhard from "Stranger Things" takes on the role of Richie Tozier in "It."

The iconic role of Pennywise is played by Swedish actor, Bill Skarsgård.

We don't see much of him, but it seems this Pennywise is much grittier than the one from the '90s.

But the absolute scariest part of the trailer comes at the very end when Georgie starts laughing and screaming maniacally.

There is literally nothing worse than creepy children laughing.

If you've never read the book or seen the miniseries, the basic idea is that It is a demon that preys on young children, and takes the form of a clown in order to lure children to It. The story follows several different children and their disappearances.

So, you know, it basically just inspired a worldwide fear of clowns in everyone. No biggie!

"It" (2017) hits theaters everywhere this fall, September 8.
