Halle Berry has signed on to star in "Class Act" - the true-life tale of a teacher from Nevada who ran for Congress after being challenged by her pupils. The star will play Tierney Cahill, a teacher from Reno, Nevada, who agreed to run on the condition her students would help her run her campaign.

Filmmakers made the unusual move of casting Berry in the part of Cahill, who is a white woman. A source close to the film said when actresses where being considered, they felt it was important to find the right actress to play the role, rather than the right white actress.

Filming is expected to start next summer.
