The first official trailer for Andres Muschietti's highly anticipated "It" is due to arrive tomorrow. In the meantime, a new -- and particularly creepy -- poster and teaser have floated up from the sewers of Derry.

The poster features what is most likely young Georgie Denbrough in a yellow rain slicker walking toward Pennywise the Dancing Clown (Bill Skarsgard), the face of fear somewhat obscured behind a red balloon. There have been steady stream of official Pennywise images, but this poster may just be the creepiest yet.  Between the word "IT" in blood red letters, the "You'll float too" tagline, and a deliciously disturbing look at Pennywise, this teaser should be enough to wring every last bit of anticipation out of fans waiting for the full trailer.

As for the teaser, it features a short voice-over from the Loser's Club, possibly Bill Denbrough (Jaeden Lieberher) and Eddie Kasbrak (Jackie Dylan Grazer). I you listen closely, you can just catch what may be some unsettling laughter from Pennywise in the background.  All and all, it's a sufficiently unsettling first taste of what's to when the trailer drops tomorrow. Check out the teaser below:

Based on the Stephen King's classic novel of the same name, "It: Part 1 - the Losers Clubs" stars Bill Skarsgård, Finn Wolfhard, Jaeden Lieberher, Jeremy Ray Taylor, Sophia Lillis, Jack Dylan Grazer, Chosen Jacobs, Wyatt Oleff, Nicholas Hamilton, Owen Teague and Logan Thompson.
