As if we weren't already excited for the It sequel, now there's one more thing to celebrate: The adult version of the Loser's Club is almost complete.

Jessica Chastain had been rumoured to play Beverly Marsh in the film and the actress involvement has been confirmed, according to The Hollywood Reporter.

Plus, James McAvoy and Bill Hader are reportedly in talks to join the cast too.

Hader will be the adult Richie Tozier, who was played by Stranger Things' Finn Wolfhard in the first movie, and McAvoy will play Bill Denbrough. Per The Hollywood Reporter, his stutter will resurface when he returns to face his past.

It director Andy Muschietti recently confirmed he's coming back for the sequel on Instagram. The post is properly captioned: “Wake up, losers. Derry is calling.” And we couldn't be more excited.

As we knew going into the first film, the It sequel will be covering the second half of Stephen King's massive book and, for most of us, we've been referring to the upcoming horror flick as IT: Chapter 2. While we may have all assumed the movie would have a “chapter two” title attached to the end of it, it comes as a bit of a surprise (or not) that the movie will actually be called It: Part 2.

In It: Part 2, we can expect to follow the Losers' Club 27 years later as they are once again face-to-face with the evil Pennywise, but this time—as adults. 

Apart from the news of the ~ official ~ title, not much is known about the upcoming Stephen King movie. 

According to ComicBook.com, the film is expected to begin filming sometime this summer with a return of the younger version of the Losers' Club. They won't play as big of a role in the new flick, but it appears that they'll be shooting new flashback scenes to add to the plot of the second film.

Be sure to be on the look out for It: Part 2 in theaters September 6, 2019.
