After a brief intermission, M. Night Shyamalan is back. In addition to the new Fox series Wayward Pines, the twist-y filmmaker also has a new movie coming out: The Visit. We first heard about the film last year, but other than the casting of Kathryn Hahn, production has remained fairly quiet. With Shyamalan’s latest hitting theaters in just four months, the first trailer has arrived to reveal just what The Visit is all about.

Admittedly, the trailer is a bit of a letdown and appears to reveal a little too much. The Visit follows a brother and sister whose mother (Hahn) sends them off to grandma and grandpa’s house for a week of elderly fun. Once the kids arrive, grandpa firmly establishes a 9:30 p.m. bedtime, ordering the children not to leave their rooms at night. As the trailer reveals (way, way too much), something is definitely not right with grandma. Shyamalan has a fondness of fairytales, so maybe this is his take on Hansel and Gretel, and grandma is a witch. Or maybe the big twist is that she’s schizophrenic, which seems like a pretty fair guess.

Honestly, I was hoping that the grandparents’ big secret involved throwing Eyes Wide Shut-style ragers every night, but what can you do.

The Visit comes courtesy of horror outfit Blumhouse Productions, the folks behind Insidious, Paranormal Activity and The Purge. The film also stars Ed Oxenbould, Peter McRobbie, Olivia DeJonge and Deanna Dunagan, and hits theaters on September 11.
