Gamer Movie (2009)

In a near-future New York, mind-control technology has taken the world by storm. Ken Castle (Michael C. Hall) has revolutionized the gaming industry with his invention of self-replicating nanites. The nanites colonize in the brain, gradually replacing the existing brain cells and allowing full control of all motor functions by a third party. The first major application of this technology allows gamers to control a real person in a pseudo community (much like current simulated worlds such as Second Life but with far more telepresence). Those who work as characters in Society are paid for their participation, unlike Castle's latest creation, Slayers, a multiplayer, third-person shooter game. Slayers allows gamers to control death row prisoners in mass-scale death matches. Any inmate who lives through 30 matches wins a full pardon. Due to Society and Slayers popularity Ken Castle has become the richest man in the world. Simon, a 17-year old gamer (Logan Lerman) has control over Kable (Gerard Butler), the most recognizable face in Slayers due to him surviving 27 matches, far more than any other participant.
Gerard Butler, formaly known as "Leonidas" in "300", in his new movie. Nothing for people with weak nerves....
