If you wait until the end of “It Chapter Two,” all you’re going to find is a blank screen and an empty theater. There are no post-credit scenes. “Post-credit scenes a la Marvel normally have a very distinct function, which is tease people about a future movie,” Andy Muschietti, the director of “It Chapter Two,” told HuffPost. “But yeah, this is, like, the idea that this is over.” Thanks to the influence of the Marvel Cinematic Universe, starting with 2008’s “Iron Man,” after-credit scenes have basically become ubiquitous among blockbuster movies. Some tease future films, such as the one in “Godzilla: King of the Monsters.” Others, such as in “Hobbs & Shaw,” seemingly just use the space to poke fun at the finale of “Game of Thrones.” The first chapter of “It” also goes somewhat without a post-credit scene, including just a sinister laugh from Pennywise after the credits roll. But it wasn’t always going to be that way.

“Something a lot of people probably don’t know is ‘Chapter One’ did have the idea to make a post-credit scene, which was Beverly Marsh picking up the phone,” Muschietti said. “So, 27 years later, post credit, you would see a phone ringing. It’s an iPhone, so it’s impossible that it’s 1989, and a hand comes in and the camera wraps around this red-haired back of a head, and we turn around, and it’s Jessica Chastain!” However, Barbara Muschietti, the film’s producer and Andy’s sister, said they couldn’t get the schedules together to shoot the scene with Chastain for their first installment of “It,” released in September 2017. “We did all that we had to do to make sure that Jess was our Beverly, and then she was, so we got our wish,” Barbara Muschietti said of “It Chapter Two.” In the new film, Chastain is joined by James McAvoy, Bill Hader, Isaiah Mustafa, Jay Ryan, James Ransone and Andy Bean as the adult versions of the Losers’ Club, who reunite to take on Pennywise one last time. “It was very important for me to get a cast that had physical similarities to their child-like counterparts,” Andy Muschietti said.
