Pennywise is back to his old tricks in the terrifying new trailer for highly anticipated horror sequel It Chapter Two.

Ahead of its online release today (July 18), the trailer was previewed at yesterday's (July 17) ScareDiego event that saw all of the adult Losers Club, including James McAvoy and Jessica Chastain, take part in a Q&A.

The new trailer shows more of the grown-up Losers Club than the first trailer that largely focused on a scene with Beverly (Chastain).

Kicking off with a tease of the sequel's take on the Jade of the Orient reunion scene ("we made an oath"), we then see the Losers Club battle Pennywise, such as in a hall of mirrors with Bill trying to save a young child from the evil clown.

And Pennywise is out for revenge after the Losers Club defeated him in the first movie: "For 27 years, I dreamed of you. I craved you. I missed you."

Horrifying.

Screenwriter Gary Dauberman recently told Digital Spy that It Chapter Two still holds some surprises for fans of the book.

"Oh, absolutely. I can guarantee that. And if you wanna know the specifics as to what, go see the movie," he teased.

As shown in the trailer, McAvoy has also been speaking about the changes with the Losers Club 27 years later. "When you leave Derry, something happens where you forget it all. I think it's like a [power] of Pennywise's," he explained.
