Kristen Stewart has signed on to star in Cali, an action project being set up by Voltage Pictures.

The actress will play Mya, who, along with her boyfriend Chris, sells a fake snuff film of her "death" before ditching town with loads of cash. Years later, Mya is forced to return to the San Fernando Valley to save the younger sister she left behind. When the couple comes back to town, they must deal with volatile former business partners, murderous porn stars, and a stone-cold killer in a cowboy hat.

Michael Diliberti (30 Minutes or Less) wrote the sceenplay and will produce with Craig J. Flores, Zev Foreman, and Kristen Stewart, who makes her producing debut on the project. Here's what Craig J. Flores had to say about the actress signing on.

"Kristen is a talented and dynamic actor, with a proven box office draw. Her role in Cali will be edgy and sexy. It will no doubt push the envelope on the public's view of Kristen's wide-ranging abilities. Voltage is thrilled to have her as a partner on this fantastic film."

It isn't known when production will begin.
