MTV.com has an article on ‘Game’ with interviews with Gerald Butler. Here is bits I pulled from it that relate to Alison and the plot of the film;

Which brings us to the film’s constantly evolving “The Sims”-meets-”The Running Man” plot. Set in a time described as “some years from this very moment,” the story follows Kable (Butler), a burly prisoner in a jail system now financed by a private company. Video games have hijacked pop culture to the point where the most popular diversion is “Slayers,” a first-person shooter set in a “Second Life”-like environment. But the avatars are actually prisoners like Kable, controlled by implants they willingly install in their brains in exchange for the faintest hope of freedom.

“We have four main games, and every single one is going to be different,” explained Butler, looking around at the motorcycles-and-machine-guns setting of one of the game’s levels. “There’s so much character and gruesomeness to it all.”

A prisoner needs to successfully complete 30 games to earn amnesty, and the script begins with Kable as the only prisoner to have ever reached 27 wins. Fifteen-year-old “3:10 to Yuma” actor Lerman is the gaming rock star who has been manipulating Kable from his wealthy family’s living room, engaged by a gaming system that follows the boy’s every gesture like a Wii on steroids, then forces Butler’s character to do the same in real life.

If you haven’t wrapped your mind around the plot at this point, it’s probably useless to mention that Kyra Sedgwick plays a reporter trying to take the game down, Ludacris and Alison Lohman are militant protesters trying to free Kable, and John Leguizamo is a fellow prisoner.
