Unknown is a 2006 American crime-thriller film directed by Colombian filmmaker Simon Brand and starring James Caviezel, Greg Kinnear, Bridget Moynahan, Joe Pantoliano and Barry Pepper about a group of men kidnapped and locked in a factory with no memory of how they arrived there. Piecing together information around them, they realize that some were kidnapped and some were the kidnappers. They decide they must work together to figure out how to get away before the gang that captured them returns.

The film was previewed before a theater audience for the first time in New York City on December 13, 2005.

In an abandoned warehouse, a handful of men slowly regain consciousness, but they have amnesia and have no idea who they are, where they are, or what has happened to them. All five seem to have been in some sort of serious scuffle; one is tied up on a chair (Joe Pantoliano), another has been handcuffed and shot (Jeremy Sisto), a third has a broken nose (Greg Kinnear), and the other two have their share of scrapes and bruises (Jim Caviezel and Barry Pepper). Everyone is asleep at the start. Caviezel's character wakes up first. He checks to make sure everyone is alive and then decides to walk around and try to find out what is going on. He discovers that all the windows have bars over them and the only door has a mechanized lock. He finds a ringing phone and picks it up. The caller asks what is going on and Caviezel tells the caller that everyone is fine. The Caller tells him he will be back in a few hours. Meanwhile, somewhere else a money drop off is going down. Mr. Coles has been kidnapped.

A film, also called a movie or motion picture, is a series of still or moving images. It is produced by recording photographic images with cameras, or by creating images using animation techniques or visual effects. The process of filmmaking has developed into an art form and industry.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating – or indoctrinating – citizens. The visual elements of cinema give motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue into the language of the viewer.

Films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.
