Linda Lovelace’s name has become a punchline. After all, she starred in the infamous 1972 porn film Deep Throat. But as this gritty biopic shows, there was nothing to laugh about behind the scenes. Lovelace (Amanda Seyfried) was regularly abused and forced to stay in the porn industry by her husband (Peter Sarsgaard). ”I keep telling myself that I’m not going to play people who I wouldn’t bring home to dinner,” says Sarsgaard with a laugh. ”People always ask me about the sex scenes, but the violence is way more intense.” Watch for cameos by Sharon Stone, Chris Noth, and James Franco — as Hugh Hefner, of course.
