Londoner Harper Marlowe (Jessie Buckley) needed a reset after the abrupt and violent death of her spouse (Paapa Essiedu), so she opted to holiday at a remote Hertfordshire B&B. As the subtly creepy behavior of the landlord (Rory Kinnear)-as well as that of all the local menfolk (Kinnear again, in multiple roles)-grows increasingly hostile, the getaway will prove anything but leisurely. Alex Garland's unnerving allegory also stars Gayle Rankin, Sarah Twomey, Sonoya Mizuno. 100 min. Widescreen; Soundtrack English.

Just gotten clean, privileged Sophie (Amandla Stenberg) dragged working-class rehab buddy Bee (Maria Bakalova) to the remote manse of vacant pal David (Pete Davidson) for a hurricane party. As the Gen-Z one-percenters engage in a murder game, the storm takes the power out for real-and as resentments and jealousies erupt, the casualties become genuine as well. Halina Reijn's dark horror-farce also stars Rachel Sennott, Myha'la Herrold, Chase Sui Wonders, and Lee Pace. 96 min. Widescreen; Soundtrack English

It was a traumatic day for therapist Rose Cotter (Sosie Bacon) when a young patient (Caitlin Stasey) complaining of tormenting visions convulsed, flashed a ghastly grin-and killed herself. There'd be more to follow, as her investigations found a string of similarly bizarre and lethal incidents... and as she encounters sundry strangers with the same evil rictus, the more certain she is she'll be the next victim. Disquieting chiller also stars Jessie T. Usher, Kyle Gallner, Kal Penn, Robyn Weigert. 115 min. Widescreen; Soundtrack English.
