Washington, Jan 28: Sarah Jessica Parker is set to play feminist author and activist Gloria Steinem in the upcoming Linda Lovelace biopic, after replacing Demi Moore for the role.

Moore, 49, dropped out of the film, starring Amanda Seyfried as the '70s porn star, after being hospitalized this week.

A 911 caller reported that the actress had gone into convulsions after she "smoked something". Moore is now seeking "professional assistance to treat her exhaustion and improve her overall health," People quoted her rep as saying.

Filming for the biopic began last month in Los Angeles. (ANI)
