Alone in the Dark is a 2005 Canadian-German-American action horror film loosely based on the fourth installment of Infogrames' video game series of the same name. Directed by Uwe Boll, the film stars Christian Slater as supernatural detective Edward Carnby (the main character in the games), Tara Reid as the scientist assisting him, and Stephen Dorff as the government operative who joins forces with them.

The film was a critical and commercial failure, and is widely considered one of the worst films ever made. Despite this, a sequel was released in 2008.

Edward Carnby (Slater) is a detective who specializes in the occult & other paranormal subjects. He was apparently the subject of strange experiments when he was a child, leaving him with heightened abilities as well as a "sixth sense" that allows him to sense the paranormal. Throughout the film, we also learn that Carnby used to work for Bureau 713, a secret government organization that seeks to protect the world from paranormal dangers.
