Our first glimpse of the cast of the forthcoming horror movie was posted earlier today in an Instagram post made by James McAvoy, who’s playing the adult version of Bill Denbrough.

The behind-the-scenes shot shows McAvoy with fellow members of the Loser's Club, young and old.

Jessica Chastain, who plays the adult version of Beverly Marsh, also posted a "transformation" picture. The snap is of herself and Sophia Lillis (who, of course, plays the young Beverly) with their faces blended together.

Check out the photos below:

It was recently revealed that all tickets for the trip to Derry, Maine have been booked.

On June 25, it was announced that Teach Grant and Jess Weixler would be joining the cast of the IT sequel. Grant is set to play Henry Bowers, who was portrayed by Nicholas Hamilton in the first film, and Weixler will play Bill’s wife.

The two will be joining recently announced Xavier Dolan (The Death And Life Of John F. Donovan director,) who will be playing the role of Adrian Mellon and Will Beinbrink (Manhattan Night,) who is set to portray Tom Rogan.

We also know that the adult version of the Loser's Club has been cast!

Jessica Chastain is set to play Beverly Marsh, James McAvoy will play Bill Denbrough, Bill Hader will take on the role of Richie Tozier, James Ransone will be Eddie Kaspbrak, Jay Ryan will play Ben Hanscom and Andy Bean will play Stan Uris and Isaiah Mustafa will play Mike Hanlon.

While the film will focus on the adult version of the club, that doesn’t mean the kids from the first film won’t make an appearance. As previously reported, the kids from the first film will appear in flashbacks during the sequel.

In addition to the new and old versions of the club appearing in the film, we also know that Bill Skarsgård will be coming back to eat the children, uhm, adults, of the Loser’s Club.

What’s more?

The new sequel is set to be a lot scarier than the first. It was also reported the forthcoming flick from Andy Muschietti is set to be so scary that the director shared you might need to invest in some adult diapers, saying:

“They’re gonna find a lot of things that resemble the first one, the humor, the emotion, the horror,” said Muschietti to CinemaCon. “People are very invested emotionally in the characters of the story.”

He continued on to say: “It’s gonna be scarier. It’s gonna be a more intense experience. So, bring your adult diapers to the theater.”

Yeah, we’re already spooked, but seriously excited, and it looks like we won’t have to wait too much longer for snippets of information. James McAvoy recently confirmed the news that filming for the forthcoming horror flick is now underway!

We can’t wait for IT: Chapter two! The new film will be hitting theaters on Sept. 6, 2019.
