Whitney Elizabeth Houston (Brown) 1963-2012

 Genre appearances included...

Rodgers & Hammerstein's Cinderella (Fairy Godmother / performer: "Prologue", "Impossible", "It's Possible", "Finale Ultimo", "There's Music in You")
The Preacher's Wife (Julia Biggs)
The BodyGuard (Rachel Marron / performer: "Queen of the Night")

 Note: The BodyGuard is not really genre, but it's use of footage from the classic 1926 film Metropolis as well as the Maria-Robotrix-influenced costume prominently featured in the video for "Queen of the Night" and the film itself make it worthy, IMHO, of inclusion.
