Stone takes role in porn biopic.

Yahoo! reports that Sharon Stone has joined the cast of the Matthew Wilder-directed ‘Inferno: A Linda Lovelace Story.’ The actress will be playing Lovelace’s mother.

Malin Akerman is attached to play Lovelace, who is famous for starring in the 1972 pornographic film ‘Deep Throat.’ The film, based on the Lovelace’s autobiography ‘Ordeal,’ will chronicles her rise to international fame and how she was forced into the pornography business by her abusive husband Chuck Traynor, played by Matt Dillon. ‘Boardwalk Empire’ actress Paz de la Huerta will also co-star.

A competing biopic starring Amanda Seyfried as the porn starlet is set to head into production around the same time as Wilder’s biopic. Rob Epstein and Jeffrey Friedman will be directing with Peter Sarsgaard (‘Green Lantern,’ ‘Orphan’) in line to play Trayor.
