After her death, her success skyrocketed with posthumous releases, praise from stars like Sting, ice skaters who skated to her music, appearances on film soundtracks, and a cover by Katharine McPhee during American Idol that made Randy, Paul, and Simon wow. Topping off this fame, Variety reports that her life is going to be turned into a biopic by AIR Productions -- headed by Amy Redford, Irwin Shapiro, and Rick Singer. As Robert's progeny describes it: "We see this film as an uplifting story of indomitable human spirit and an insightful look into the life and personality of an amazing talent." This project seems to be in the embryo stage -- there's no word of a script, director, or specific focus.
