Demi Moore is apparently making an appearance in Lovelace.
The Ghost star is set for a cameo as political activist Gloria Steinem in the upcoming biopic about adult actress Linda Lovelace, reported Variety.
The OC's Adam Brody and Heroes' Eric Roberts are also rumoured to have joined the cast list.
Amanda Seyfried is already on board as the porn star, with Peter Sarsgaard as her husband.
Sharon Stone, Juno Temple, Wes Bentley and Hank Azaria are in talks to appear, with James Franco possibly portraying Playboy founder Hugh Hefner in Rob Epstein and Jeffrey Friedman's movie.
Gloria is the founder of Ms Magazine, which published an article discussing Linda's abusive relationship with her pornographer husband, whom she claimed coerced her into the erotic film industry.
Demi - who announced her plans to divorce husband Ashton Kutcher in November - will next be seen in ensemble financial drama Margin Call alongside Kevin Spacey, Jeremy Irons and Paul Bettany, to be released on January 13.
