->''"Because you were home"''
-->-- '''One of the strangers ForTheEvulz motivation.'''

The 2008 (but filmed in 2007) debut movie of filmmaker Bryan Bertino. The movie is about a couple, Kristen [=McKay=] (Creator/LivTyler) and James Hoyt (Scott Speedman) being ambushed in James' family's vacation house by mysterious strangers apparently ForTheEvulz. A sequel is currently in some stage of development.

Not to be confused with the 2006 horror film ''Film/{{Ils}}'' (aka ''Them''), which has a similar premise.
!!Tropes used in this film:

* CarFu: The Strangers use their car to slam into the couple's to prevent their escape.
* DangerTakesABackseat: The male lead makes a dash for the car to see if it's still working. He sees that all the windows of the car have been smashed in, but doesn't bother to look around his car at all before getting in. [[spoiler:He doesn't get killed (there), but there WAS someone in the backseat.]]
* DevelopingDoomedCharacters: The first twenty-thirty minutes of the movie.
* TheFaceless: The killers as they're always masked and [[spoiler:their faces are not revealed to the audience]].
* DoesNotLikeShoes: Kristen is barefoot for the majority of the movie.
* DullSurprise: The children at the end who [[spoiler: explore the Hoyt's house after the Strangers have seemingly killed them]]. Okay, you can't always expect much from child actors, but how hard is it to show a little discomfort?
* TheFamilyThatSlaysTogether: The three masked people, presumably.
* ForTheEvulz: The killers' motive (and the movie's tagline) is ''Because You Were Home''.
* HowWeGotHere: The movie begins with the end and then rewinds.
* [[MalevolentMaskedMen Malevolent Masked People]]: The Strangers.
* NoNameGiven: The Strangers are credited as "Doll Face", "The Masked Man", and "Pin-Up Girl", but none of those names are heard in the film.
* NothingIsScarier: This was the main source of the scares in the movie. How effective the scares are depends on the viewer (see YMMV).
* OffScreenTeleportation: The Strangers are adepts at this.
* RedHerring: The smoke detector. When Kristen takes it off of the ceiling early on and leaves it lying on the floor, it seems like a foregone conclusion that the strangers will later try to burn the house down. They don't.
* TheUnreveal: The Strangers at the end [[spoiler: take off their masks]] but the movie cuts away before you can [[spoiler: see their faces]].
* TooDumbToLive: ''All the good guys''. Kristen just runs around the house terrified and manages to injure herself, James manages to tell his girlfriend to ''stay in the middle of danger'' while he goes looking for help, and their friend Mike, despite the various things suggesting foul play (including ''a rock thrown on his windshield'') does not think for one second about calling the police or even ''calling for his friends'' which leads to [[spoiler: AccidentalMurder]].
* VeryLooselyBasedOnATrueStory: Director Bryan Bertino recounted a story from his childhood when a stranger came to his house at night, asking for a woman that wasn't there. The next morning, it turned out that the houses that didn't answer the door had been broken into.
** He also said that he was inspired by the [[UsefulNotes/CharlesManson Manson murders]] and a [[http://en.wikipedia.org/wiki/Keddie_Murders 1981 homicide where a woman, her two children, and a third child were murdered in their rural home in the Sierras, which turned up absolutely zero suspects.]]
