Eli Roth's Horror Thriller Knock Knock Unleashes Scares with Teaser Trailer

Keanu Reeves frighteningly learns that some doors shouldn’t be opened in the new teaser trailer and stills from his upcoming horror film, ‘Knock Knock.’ The psychological thriller’s helmer, Eli Roth, unveiled the clip last night on Facebook before the movie had its premiere at the Sundance Film Festival, during the Park City at Midnight section.

‘Knock Knock’s teaser trailer follows Reeves’s character, Evan Webber, as he hears a knock on his front door during a rain storm. He suspiciously asks who’s there as he approaches the door, and finds two young women desperate to find shelter from the rain. After he lets the two women in, they then ask him where his wife is, and he tells them she’s at the beach with their two kids. While the trio spends time together as they wait for the storm to end, Evan insist he can’t spend become involved with them, but they assert he can.

The Sundance Film Festival has released the following synopsis for ‘Knock Knock’:

Evan Webber (Keanu Reeves) is living the dream. Just look at his beautiful, successful wife, his two wonderful kids, and his truly stunning house—which he designed himself. Of course he did. Things are going so well, Evan doesn’t even mind spending Father’s Day alone while the rest of his family heads out for a beach weekend. Then there’s a knock on the door.

The two young women (Lorenza Izzo and Ana de Armas) standing on Evan’s doorstep are where Evan’s dream takes a nightmarish turn. Given co-writer/director Eli Roth’s well-deserved reputation for creating cinematic discomfort, it should come as no surprise what happens next: Things get weird, and then dark, and then much, much, much darker. But this is no splatter film, so Roth keeps the horror nice and psychological as Evan’s life—and house—get ripped apart, piece by beautiful piece.

In addition to helming ‘Knock Knock,’ Roth also co-wrote the psychological thriller with Nicolas Lopez and Guillermo Amoedo, who he previously worked with on such horror films as ‘Aftershock’ and the as-yet-to-be-released ‘The Green Inferno.’ Besides Reeves, Izzo, and de Armas, ‘Knock Knock’ also stars Aaron Burns, Ignacia Allamand and Colleen Camp.
