Actress Sharon Stone has joined the cast of Inferno: A Linda Lovelace Story for director Matthew Wilder (Your Name Here).

Sharon Stone will play the mother of porn star Linda Lovelace, who we reported last year will be portrayed by Malin Akerman. The biopic will be based on Linda Lovelace's autobiography, Ordeal: An Autobiography, which she co-wrote with Mike McGrady. The book chronicles Linda Lovelace's rise to international fame after starring in the XXX classic Deep Throat, and how she was forced into the porn industry by her abusive husband.

Matthew Wilder will direct Inferno: A Linda Lovelace Story from his own screenplay, which is adapted from Ordeal: An Autobiography. It isn't known when production will begin, although it is reported that Sharon Stone will shoot The Mule before working on Inferno: A Linda Lovelace Story.
