Want to be a fly on the wall of the IT set?

Filming wrapped last year on Andy Muschietti’s first of two film adaptations of IT, and Muschietti was awesome enough to invite us all on the set through the power of social media. He and sister Barbara, who produced, took a ton of behind the scenes shots on set that they each uploaded to their Instagram accounts during production, and they’ve continued sharing more to this day.

If you haven’t been following along, you can check out a gallery of the behind the scenes images below. And be sure to follow @andy_muschietti and @barbaramus for many more!

In theaters September 8, 2017, the film is set “in a small town in Maine, where seven children known as The Losers’ Club come face to face with life problems, bullies, and a monster that takes the shape of a clown called Pennywise.“

The cast also includes Jaeden Lieberher, Finn Wolfhard, Nicholas Hamilton, Jack Dylan Grazer, Wyatt Oleff, Chosen Jacobs, and Jeremy Ray Taylor.
