Moore had been slated to play feminist Gloria Steinem in the story of the porn actress who became famous for her role in Deep Throat, one of the films that launched the 1970s porn chic movement.
According to a statement from her publicist-
Because of the stresses in her life right now, Demi has chosen to seek professional assistance to treat her exhaustion and improve her overall health. She looks forward to getting well and is grateful for the support of her family and friends.
Sevigny, however, will not be stepping into Moore’s abandoned role. Instead, she will be playing a feminist journalist writing a story on the titular porn actress.
Previously announced as Inferno: The Linda Lovelace Story, Lovelace stars Amanda Seyfried in the title role with Rob Epstein and Jeffrey Friedman directing and Peter Sarsgaard, Debi Mazar, Cory Hardrict, Adam Brody, Eric Roberts, Hank Azaria, Bobby Cannavale, Chris Noth, Robert Patrick, Wes Bentley, Sharon Stone and Juno Temple rounding out the cast.
