A pair of femme fatales wreak havoc on the life of a happily married man (Keanu Reeves).
The movie Knock Knock is directed by Eli Roth and was released in only a handful of movie theaters by Lionsgate Premiere, the ultra low budget division of Lionsgate that releases movies in a handful of theaters day-and-date with Video On Demand (in and of itself, a dreadful business model).
The majority of movie critics poo-pooed Knock Knock saying, Knock Knock brings a lot of talent to bear on its satirical approach to torture horror, but not effectively enough to overcome its repetitive story or misguidedly campy tone.
