CANNES, France (AP) — Destiny's Child alum LeToya Luckett will star as Dionne Warwick in a planned biopic of the R&B singer.

The 75-year-old Warwick was in Cannes on Friday to announce the project, which will also co-star Lady Gaga, Danny Glover and Olympia Dukakis. Gaga is to play the late British singer Cilla Black.

The film, based on Warwick's memoir "My Life As I See It," will focus on the years 1962 through 1968. The five-time Grammy winner's hits include "Say a Little Prayer" and "That's What Friends Are For."

AMBI Pictures will produce. The recently launched AMBI, founded by Italian producer Andrea Iervolino, made headlines earlier this year when it claimed to be distributing a movie starring the Pope. The Vatican quickly denied that.

"Dionne" is being shopped for buyers in Cannes.
