Pennywise is back.

The teaser trailer for 'It: Chapter Two' dropped Thursday and it's fantastically horrifying, as expected.

Warner Bros.' sequel to the wildly successful 2017 "It," cinema's highest-grossing horror of all time, is scheduled to hit theaters Sept. 6.

We see the reunion of the Losers' Club, now portrayed by Jessica Chastain as Bev; James McAvoy as Bill; Bill Hader as Richie; Jay Ryan as Ben; Isaiah Mustafa as Mike; James Ransone as Eddie; and Andy Bean as Stan.

Bill Skarsgård returns as Pennywise, or It.

Stephen King promoted the teaser trailer's release Tuesday, writing that the film was "terrific" and that "you'll float."
