Demi Moore joins porn biopic Lovelace

Los Angeles - Demi Moore has been tipped to star in Lovelace.

The Ghost actress looks set to portray feminist activist Gloria Steinem in the movie, a biopic about 1970s porn legend Linda Lovelace, who will be played by Amanda Seyfried.

Adam Brody and Eric Roberts have also joined the cast of the film - which is set to be directed by Rob Epstein and Jeffrey Friedman - with Sharon Stone in line to play the titular character's mother, and Peter Sarsgaard set to portray Linda's spouse Chuck Traynor.

Gloria co-founded Ms. magazine which went on to publish an article entitled The Real Linda Lovelace, which discussed Linda's relationship with her pornographer husband Chuck, who steered her into the adult movie industry before she eventually quit and sought a divorce.

The 77-year-old journalist also penned the introduction for Linda's 1986 memoir Out of Bondage and attended a press conference for the porn star's 1980 memoir Ordeal alongside other members of the feminist group Women Against Pornography.

Adam is set to play Harry Reems - Linda's co-star in 1972 movie Deep Throat - and Eric, the older brother of Julia Roberts, is in line to star as lie detector expert Nat Laurendi, who administered a polygraph test to Linda at her publisher's request.
