THIS IS FPS!
Gerard Butler is gonna teabag your ass in Slayers.
Kable (Butler) is the latest "running Man" in this massively popular "online" FPS where deathrow inmates get a chance to be pardoned if they survive in Slayers. Originally titled Citizen Game, Gamer hits the sliver screen 9/4/09. With Lionsgate producing it and it's R rating fans of Infinity Wards Modern Warfare, Bungies Halo, and all the other FPS's will probably flock to see this!
As far as games to film goes this looks like it will work because it's not based directly on a specific franchise.
