Sharon Stone is set to star in Running Wild, a drama from ESX Entertainment, the newly launched outfit from Lucas Oil head Forrest Lucas and Ali Afshar. Alex Ranarivelo is directing the film, from a script by Christina Moore and Brian Rudnick. Principal photography begins this week in Napa, CA. The pic centers on Stella Davis, a widow who saves her ranch by working with convicts to rehabilitate a herd of wild horses that wandered on to her property. She must fight prejudice, greed, bureaucracy and vanity –- including her own –- to finally understand that there is no better remedy to misfortune than helping another living creature. Stone will play the baddie role of Meredith.

ESX, launched last month, has a pic slate that includes the social issue drama The Wrong Side Of Right with Lea Thompson, James Remar, Allison Paige and Jayson Blair; coming-of-age story The Wizard starring Jon Voight, William Fichtner, Gabriel Basso and Afshar; and Afshar’s Born To Race franchise which includes the original film, its sequel Born To Race: Fast Track and a TV series.
