Sparkle looks like it has a lot going for it. It also happens to be the movie Whitney Houston finished before she died. She plays the mother of a trio of singing sisters destined for stardom during the Motown era. Title character is played by Jordin Sparks, and her sisters by Carmen Ejogo and Tika Sumpter. Derek Luke, Mike Epps, Omari Hardwick and Cee-lo Green also star in the project directed by Salim Akil and written by Mara Brock Akil from a story by Nicholas August and Howard Rosenman. The TriStar release is slated to open August 17.
