Sinister 2 seeks to further expand the mythology of the child-eating pagan deity Mr. Boogie

Focus Features' Sinister 2, the sequel to 2012's hit Sinister, will be hitting US theaters beginning August 21. Directed by Ciaran Foy from a screenplay written by Scott Derrickson and C. Robert Cargill, the second installment in the newest supernatural horror film franchise will next center on a young mother and her twin sons who move into a rural house that is marked for death.

In the first Sinister film, a true-crime author, Ellison Oswalt (played by Ethan Hawke), moves into a house where almost an entire clan was recently killed by hanging. When he moved out, it triggered an action that awoke an ancient child-eating pagan Babylonian deity named Bughuul which caused the death of his own family. Made with a budget of just $3 million, the film reportedly grossed $82 million at the box office worldwide.

Shannyn Sossamon portrays Courtney, the young mother in Sinister 2, with real life twins Robert and Dartanian Sloan acting in the movie as her 9-year-old twins, Dylan and Zach. James Ransone returns to reprise his role as the unnamed local deputy, as will Nick King who will once more portray Bughuul, aka Mr. Boogie. Joining them in the cast are Tate Ellington as Dr. Stromberg, Laila Hailey as Emma, Lucas Jade Zumann as Milo, Lea Coco as Clint, Olivia Rainey as Catherine, Jaden Klein as Ted, Caden M. Fritz as Peter, Robert Finlayson as Milo's father, and Sierra Doyle as Mio's sister.

Sinister 2, now in post-production, is being financed by eOne. Jason Blum of Blumhouse is producing it with Derrickson. Charles Layton, Brian Kavanaugh-Jones. Xavier Marchand and Patrice Theroux are serving as executive producers. Amy Vincent is the cinematographer and Ken Blackwell will handle the editing.

Co-creator Scott Derrickson, who directed the original, on what to expect from the sequel, told Shock Till You Drop: "It's a completely different approach. The script was so hard to write because Cargill and I were determined to do a sequel that we wanted to see. And what we weren't going to do was, hey, another family, another box...same formula. Sinister 2 takes a different point of view, literally. When you see a sequel, you want to see an expanding mythology and an expanding point of view. It's very hard to do, but because we love the genre and seen so many horror franchises - mostly inferior ones - we're taking our best shot at making a worthy sequel."
