Viewers got a first glimpse of Whitney Houston's upcoming film Monday when NBC's "Today" show premiered a trailer for the much-awaited release, and a fuller clip debuted on Yahoo! Movies. A remake of the 1976 original, "Sparkle" stars Houston as the mother of three girls who form a singing group and struggle with fame and drug addiction. The trailer displayed the daughters, including "American Idol" winner Jordin Sparks, in performance. Houston is prominent throughout, at one point singing the classic gospel song "His Eye Is on the Sparrow."
