Summers have become home to the superhero blockbusters, but this year, a horror flick scared up some great anticipation. It, the New Line Cinemas and Warner Bros. adaptation of Stephen King’s incredible novel, has been enjoying plenty of buzz and followed through by breaking some box office records.

In the opening weekend, It, made $123.1 million domestically. It had the third largest opening weekend of 2017, after Beauty and the Beast and Guardians of the Galaxy Vol. 2. Additionally, it had the second largest R-rated opening, after 2016’s Deadpool, and now holds the largest opening weekends for a September debut, the biggest horror movie, and Stephen King adaptation.

A sequel for the movie has been expected since the first movie was filmed and while it hasn’t been greenlit yet, plans are already in the works. In King’s novel, the story takes place in a few time periods, primarily with the Losers Club as preteens, then 27 years later when they are adults in their mid-thirties. The first movie focuses singularly on the story of when they are kids, meeting, forming the Losers Club, and fighting Pennywise for the first time.

The sequel will feature the adult portion of the story. Six of the seven members have left town, scattering all over the country, and becoming quite successful. But, they return to Derry, Maine after called upon by the only member who stayed in the small town. The kids from the first movie will appear in the sequel as memories from their adult counterparts.

The adult casting has not been announced, though the process is likely in the works.

It’s likely that screenwriter Gary Dauberman will write the sequel with Andy Muschietti is expected to return as the director. Producers Barbara Muschietti, Roy Lee, Dan Lin, Seth Grahame-Smith, and David Katzenberg are also expected to return.

It stars Jaeden Lieberher, Jeremy Ray Taylor, Sophia Lillis, Finn Wolfhard, Chosen Jacobs, Jack Dylan Grazer, and Wyatt Oleff as the Losers Club with Bill Skarsgård as Pennywise.
