Whitney Houston was supposed to make a big-screen comeback in Sparkle, a remake of a 1976 movie loosely based on The Supremes' story. Houston contributed two songs and stars as the mother of three daughters who form a music group, and the New York Post notes that the film is still on track for its original August release date—or perhaps as early as Memorial Day. Pushing the film up "absolutely isn't being done to make money," an apparently straight-faced source tells Radar. "The reasoning is that Whitney's fans will want to see her in this movie, in which she gives a remarkable performance." In other sad movie news, the president of Fox 2000 Pictures tells Vulture that the planned sequel to Waiting to Exhale will move forward without Houston. Who could take Houston's place? The idea of Oprah Winfrey "isn't inconceivable," the president says. (A remake of The Bodyguard is also in the works.)
