How do you follow up the biggest horror movie ever? Make the evil dancing clown really mad.

After Pennywise (Bill Skarsgard) was defeated by the youngsters of the Losers' Club in 2017's hit adaptation of Stephen King's "It," he returns yet again to Derry, Maine, to haunt his now-grownup foes in "It Chapter Two," opening Sept. 6.

While the first trailer offers us some creepy glimpses at Pennywise, it mostly features one seriously freaky old lady.

A grown-up Beverly Marsh (Jessica Chastain, taking over for Sophia Lillis) comes back to her childhood home and finds an elderly woman there, who offers her tea. Let's just say the beverage is the only soothing part of their encounter.

Though the young actors from the first "It" return for the sequel, the first footage from the highly-anticipated flick showcases the adult versions of their characters.

This time around, "SNL" alum and "Barry" star Bill Hader plays Richie Tozier (portrayed by "Stranger Things" actor Finn Wolfhard in the original), while "X-Men" alum James McAvoy takes over for Jaeden Martell as Bill Denbrough. James Ransone ("Generation Kill") inherits the role of Eddie Kaspbrak, who was played by Jack Dylan Grazer the first time around. The crew also includes Isaiah Mustafa as Mike Hanlon (originally Chosen Jacobs) and Jay Ryan is a grownup Ben Hanscom, played by Jeremy Ray Taylor in the first "It."

And naturally, we've got Pennywise up to his old tricks: luring kids to their doom and flying high with his trademark red balloons.
