The film, directed by Eli Roth (The Green Inferno, Hostel: Part II, Cabin Fever), stars Keanu Reeves, Lorenza Izzo, and Ana de Armas. KNOCK KNOCK will be released in theaters on the US in a date TBD. Evan (Reeves) seems like the perfect guy. He’s an architect, lives in a beautiful California home, has two kids and a lovely talented wife. One afternoon, the wife and kids go to the beach but Evan has to stay home and work. It’s raining, he’s alone, listening to music, and there’s a knock at the door. Two beautiful young girls, played by Ana De Armas and Lorenza Izzo, are standing in the cold. They’re drenched, lost and just want to come in to dry off and use the phone.
