Warner Bros. has released the first cast photo for the follow-up to last year's blockbuster horror film, "It," to celebrate the start of filming. The sequel, "It: Chapter Two," follows the adult versions of the Losers' Club seen in the first film, who were terrorized by the murderous clown Pennywise in the small town of Derry.

27 years later, the Losers' Club is reunited when Pennywise makes his return. The movie's official Twitter tweeted the photo on Monday with the caption "Back to Derry with these Losers."

From left to right, the photo features Jessica Chastain (who plays an adult Beverly), James Mcavoy (Bill), Isaiah Mustafa (Mike), Jay Ryan (Ben), James Ransone (Eddie), Bill Hader (Richie), and Andy Bean (Stanley).

The movie also stars Bill Skarsgard, who's returning as Pennywise; Teach Grant as an adult Henry, the neighborhood bully; Xavier Dolan as Adrian Mellon, who is a bullied gay man in the Stephen King novel; and Will Beinbrink as Tom Rogan, Beverly's abusive partner in the novel. 

"It: Chapter Two" comes to theaters September 6, 2019.
