The now-untitled sci-fi thriller, which used to be called Game (from Crank writer/directors Mark Neveldine and Brian Taylor), continues to put together one heck of a varied cast. They've got top names like 300's Gerard Butler, and even some old faces to spot. Last month, a certain serial killer and ex gay mortician (Michael C. Hall) joined the cast, which also includes Alison Lohman, John Leguizamo, Amber Valletta, and Kyra Sedgwick. (Johnny Whitworth is also involved -- you might remember him as the pensive artist in Empire Records.) Now Coming Soon reports that two more are added to the list -- one Mr. Chris "Ludracris" Bridges, and the toughest chick to hit the movies Zoe Bell (Death Proof). (Movies have tough women, but rarely are the tough women just as tough off the big screen.)

In a dystopian future, the film is about a mass-scale online computer game called "Slayers" where some humans control other humans. The top player, Kable (Butler), is the top warrior, and as everyone tracks his every move, he struggles to regain his self and bring down the imprisoning system. Ludacris will play one of Alison Lohman's "resistance group called HUMANZ that is protesting the way that the prisoners are being used as part of these video games." Bell, well, her character hasn't been shared, but I am pretty sure that she'll be a fellow warrior, or maybe a covert op of the resistance group. The flick is currently in production, but you're going to have to wait until 2009 to see it.
