A new film tells the story of an American student studying abroad in France. She ends up in prison, accused of murdering her roommate. And her father, played by Matt Damon, goes on a pursuit to prove her innocence. If the story sounds familiar, it's because, as Vanity Fair put it, the director, Tom McCarthy, was, quote, "directly inspired by the Amanda Knox saga," a phrase Knox says inaccurately frames the truth about what happened.
