Sarah Jessica Parker explains the last-minute phone call she received last week asking her to read for Demi Moore's part in the upcoming biopic Lovelace, which Demi had to pull out of when she decided to enter an addiction treatment center.
Sarah revealed to ET at last night's annual amfAR New York Gala that producers relayed their "sense of urgency" and said she had to read the script quickly because they were down to their final few days of shooting Lovelace, a movie based on the life of porn actress Linda Lovelace.
The film -- set for release later this year -- stars Amanda Seyfried as Lovelace and Sarah was chosen to replace Demi in the role of the famous feminist activist Gloria Steinem. Sarah said things happened so quickly that she didn't have much time to think much about the process, which she said was in many ways "daunting."
Also stopping by to chat was model/actress Carol Alt, who sounded off on the controversy about celebrity 911 calls being released to the media in the wake of Demi's recent health scare at home. "No, I think that's horrible, something has to be private in this life. When you're in your worst moment, the last thing you want is that splashed on the front page."
Carol also said she understands what Demi must have been going through before her split with Ashton Kutcher because she too is with a younger man.
