Keanu Reeves regrets answering the door in new Knock Knock trailer

A new trailer has appeared online for Knock Knock, Eli Roth’s new horror film in which Keanu Reeves plays a family man who strays from the kind of appropriate behaviour for a married father, and finds himself paying for it in spades. Should really have kept it in your pants there, buddy…

The new trailer jumps straight into the living nightmare in which Reeves finds himself, as Ana de Armas and Lorenza Izzo set about punishing him for his crimes. Kinky and chilling in equal parts, this new sneak peek is seriously disturbing. Just when you think it can't get much worse, the trailer resets itself to where it all started, with the 'knock knock' at the door from which the film takes its name.

Check out the new trailer, below…

It looks like suitably chaotic stuff, with the two female leads doing an excellent job of flicking between sexy and utterly terrifying, while Reeves freaks out appropriately. Looks like it’s going to be a long day for poor old Keanu.

Co-starring Ignacia Allamand, Aaron Burns and Colleen Camp, Knock Knock will open in cinemas on October 9 2015.
