Task: Question Answering
Input (English): passage: The Strangers is a 2008 American slasher film written and directed by Bryan Bertino. Kristen (Liv Tyler) and James (Scott Speedman) are expecting a relaxing weekend at a family vacation home, but their stay turns out to be anything but peaceful as three masked torturers leave Kristen and James struggling for survival. Writer-director Bertino was inspired by real-life events: the Manson family Tate murders, a multiple homicide; the Keddie Cabin Murders, that occurred in California in 1981; and a series of break-ins that occurred in his own neighborhood as a child. Made on a budget of $9 million, the film was shot on location in rural South Carolina in the fall of 2006.
