Sex and the City fans will get a dose of Sarah Jessica Parker as another feminist icon, Gloria Steinem, in the upcoming movie Lovelace, a story about a porn star who fought the industry in the early 1980s. SJP is taking over for Demi Moore, whose health troubles have cost her the role. Moore pulled out of the movie this week after a medical emergency forced her to go to the hospital, where she was treated for exhaustion. Moore has already left the hospital, but her schedule is uncertain. Parker will begin shooting the movie on Monday.
