Gamer is a 2009 American science fiction action film written and directed by Mark Neveldine and Brian Taylor.

Alongside Butler and Lerman, it also stars Michael C. Hall, Ludacris, Amber Valletta, Terry Crews, Alison Lohman, John Leguizamo, Sam Witwer and Zoë Bell.

The first application of Castle's "Nanex" technology is a virtual community life simulation game, Society, which allows gamers to manipulate live actors as their avatars.

He then creates Slayers, a third-person shooter where the "characters" are death-row prisoners using real weapons in specially designated areas.

An activist organization called the "Humanz" hacks a talk-show interview with Castle and claims that his technology will one day be used to control people against their will.

Kable/Tillman's estranged wife, Angie, works as a Society character, but in spite of her earnings, she is refused custody of their daughter, Delia, who has been placed with a wealthy foster family.

Kable is brought to the Humanz' hideout; he refuses to help their fight against Castle but learns of Angie's current location in Society.

He plans to release airborne nanites, which will infect the entire country within six months, giving him ultimate control.

In May 2007, Lakeshore Entertainment re-teamed with Mark Neveldine and Brian Taylor, the creators of Crank (2006), to produce a "high-concept futuristic thriller" called Game.

Neveldine and Taylor wrote the script for Game and were slated to direct the film, while actor Gerard Butler was cast into the lead role.

The site's critical consensus reads, "With all of the hyperkinetic action and none of the flair of Mark Neveldine and Brian Taylor's earlier work, Gamer has little replay value.
