Rhianna is the only potentially plausible candidate for the part. She has an edgy fashion image and she’s very thin and still young enough to play a woman who would be launched as a major model. However I have no idea if she can act or be charismatic in a film role. She’s only one movie so far, an ensemble role in Battleship [[based on the board game) last year and the movie had no impact, positive or negative, on her career. Beyonce would have to do some extreme dieting to get in shape to convince us she’s a high fashion model and she’s pretty much a stiff on screen anyway. Tracy Ross Ellis is nearly 40, she’s too old.
