A paved stretch of road with working streetlamps was built in the woods by the production crew for use in the film.
At the beginning of the film, in a voice-over, Lizzy says "My mom tells me there's no such thing as monsters. But she is wrong." This phrase is similar to one in the film Alien: Resurrection (1997), where Ripley, also in a voice-over says: "My mommy always said there were no monsters. No real ones. But there are."
Previously titled There Are Monsters.
Scott Speedman starred in another film directed by Bryan Bertino, The Strangers (2008).
