The 'It' sequel just got an official release date — here's everything we know

It 2 Warner Bros

The amazing box office for "It" — the adaptation of the classic Stephen King book — just keeps climbing.

After taking in over $123.4 million its opening weekend, the biggest opening ever for the month of September, the movie is now the highest-grossing R-rated horror of all time.

Now Warner Bros. has officially pulled the trigger on a sequel. Chapter two of the story will be released September 6, 2019, according to the studio.

Always intended to be two movies, the first, called "Chapter One" at the end of the movie, looks at the Losers Club as kids when they first encounter Pennywise. The second will then jump to present day when the losers are adults and must return to Derry to take on Pennywise one last time. This mirrors the structure King did with the book.

"It" director Andres Muschietti revealed some plans he has for the sequel to Entertainment Weekly.

Below is everything we know that will happen in the sequel:

Warning: Spoilers coming!

We'll still see the kid version of The Losers Club.

Despite the movie taking place 27 years after the events in the first "It" movie, Muschietti said there will be a place for the younger version of the losers as they will appear in flashbacks.

This will continue on one of the best elements of the first movie: the wickedly fun interactions between all the friends. But also flashing back brings more depth and understanding in the internal fears each loser still struggles with as an adult.

Will the adult losers be known actors or unknowns?

Almost instantly people took to social media after seeing "It" to throw out names of actors who could play the adult version of the Losers Club (Jessica Chastain as the fiery Bev? Chris Pratt as the once chubby Ben?). And though Muschietti admits he and his producers have been thinking about what do to since filming wrapped on the movie, there's still no official decision on how they will handle the casting.

The 1990 "It" TV movie was prominently made up of character actors (John Ritter was the only recognizable name), but times have changed, and with the success of the first movie there may be pressure to get at least a few stars in the club.

The one who stays in Derry becomes a librarian junkie.

One knock on "It" is Mike doesn't get a lot of screen time compared to the other losers. But that will likely change in Chapter Two.

Mike is the one member who doesn't leave Derry. He stays to watch for the return of Pennywise while working as a librarian, and staying behind, he ends up taking the brunt of Pennywise's powers.

“My idea of Mike in the second movie is quite darker from the book,” Muschietti told EW. “I want to make his character the one pivotal character who brings them all together, but staying in Derry took a toll with him. I want him to be a junkie actually. A librarian junkie. When the second movie starts, he’s a wreck.”

Mike will also take part in a ritual that will bring him better understanding of the origins of the alien behind the Pennywise clown, and how the defeat it for good. This is a portion of the book that was cut out of the first movie, but will certainly be of importance in the sequel.
