Houston served as executive producer of the movie, which had already finished filming in Detroit when she died in Beverly Hills on Feb. 11 at age 48.
A brief preview shared with theater owners Wednesday night at the CinemaCon conference in Las Vegas featured Houston's trademark dazzling smile as she danced in a living room in celebration.
The remake of the 1976 movie stars Houston as the mother of three girls who form a singing group and struggle with fame and drug addiction. The movie, scheduled for release in August, was seen as a comeback vehicle for the superstar, whose career suffered in recent years as she battled with drug and alcohol abuse.
The preview footage largely focused on Sparks, who was seen playing a piano in a modest home, glasses dangling from her nose. In later scenes, she appeared glammed up in sparkling, curve-hugging gowns. It's the American Idol winner's first notable Hollywood role.
Houston labored for 12 years to get "Sparkle" on the big screen. The film marked her first return to cinema since 1996's "The Preacher's Wife." Her Hollywood debut came 20 years ago in the blockbuster movie "The Bodyguard."
