13 is an English-language remake of the 2005 French film 13 Tzameti.

Vincent "Vince" Ferro (Sam Riley) overhears people talking about a dead man who was going to start a well-paid job. Ferro, in need of money, steals an envelope containing the instructions for the job. He arrives at an event in a secluded place. He is ordered to strip, and his boot heels are cut off, in order to check for surveillance equipment. The organizers accept him for the job instead of the dead man. The job is participation in a series of Russian roulette games. There are several participants, identified by number. In each round, the participants have to spin the cylinder of their revolver, and shoot when the light of a special lightbulb is switched on. The event is organized for the enjoyment of rich spectators, who place bets on who will survive, one of them being Jasper Bagges (Jason Statham), who bets on his brother Ronald (Ray Winstone), who was brought from the mental institution.

In the first round, the participants each get one bullet in their revolver, they are arranged into a circle, and each has to aim his revolver at the man in front of him. Ferro tries to back out, but he is forced to participate. As #13, he survives the first round and fires his gun only after being threatened with death. In the second round, in which two bullets are placed in each gun, Ferro survives only because the man behind him is killed before he could fire. In the third round, with three bullets in each gun, Ferro again survives, along with four other men. Ferro is one of two survivors randomly chosen to participate in a duel. The three others are finished and get a large sum of money. One of them, Patrick Jefferson (Mickey Rourke) was brought from prison, where he served a sentence, and is surprised that he is also free now, and he is escorted by Jimmy (50 Cent), one of the employees.

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.
