Who knows if the usually squeaky-clean Amanda Seyfried can plumb the sordid depths of the life of Linda Lovelace, the Deep Throat star-turned-anti-porn activist? Not us, but we're gutter-minded enough to be curious about how she fares in this account by bio-film masters Rob Epstein and Jeffrey Friedman. Our prurient curiosity is further aroused by the presence of an all-star ensemble, including Hank Azaria, Wes Bentley, Adam Brody, Bobby Cannavale, James Franco, Sarah Jessica Parker, Peter Sarsgaard, Chloe Sevigny, Sharon Stone and Juno Temple.
