Knock Knock is a 2015 psychological horror film directed by Eli Roth, known for his work on films like Hostel and Inglourious Basterds. The movie stars Keanu Reeves, Lorene Scafaria, and Nathalie Emmanuel in lead roles. The film's plot revolves around a man who answers a strange knock on his door, which leads to a series of terrifying events.
The movie begins with Keanu Reeves playing the role of Jeff, a recently separated father who is trying to reconnect with his children. One evening, while he's working from home, there's a knock on the door. He answers it to find two young girls, Izzy (Nathalie Emmanuel) and Eve (Lorene Scafaria), who claim to have been friends with his children in school. They ask if they can use his phone to call their parents, and Jeff, being a kind-hearted person, allows them to come in.
As the night progresses, Jeff becomes increasingly uncomfortable with the girls' behavior, which seems strange and erratic. The girls start to manipulate Jeff, and he realizes that they might not be who they claim to be. The situation takes a dark turn, and Jeff finds himself trapped in his own home, with the girls wreaking havoc on his life.
Eli Roth's direction is commendable, as he masterfully builds tension and creates an atmosphere of unease. The cinematography by Shawn Christensen adds to the film's eerie feel, with close-ups and medium shots that make the viewer feel claustrophobic.
Keanu Reeves delivers a solid performance as Jeff, bringing a sense of vulnerability and desperation to the character. Nathalie Emmanuel and Lorene Scafaria shine as the unsettling and unpredictable girls, Izzy and Eve. Their chemistry on screen is undeniable, and they play their roles with conviction.
