How about Keith Richards?

no no no to all of them i'm not a fan of Whitney or Rihanna but surely Whitney deserves better than that little hoe playing her and Rihanna can't sing at all , you're getting probably the worst singer ever to play someone who is considered "the voice"? suggestion: how about Leona Lewis,she has the voice to pull it off ?

Here it is no I will say this again please put someone that will do Whitney justice and can sing, keep looking for that right guide there are some real good voices that can do this singer very well and also, do the acting as well go see a play even a musical that will give you a price that the film that is done on this singer justice and than the real money will be made.

I think the beauitful Tamyra Gray can sing and do Whitney she got the looked she and Kelly Clarkson did song of together a Whitney sound great....

If Rihanna were to play Whitney Houston then I guessthey could get Chris Brown can play Bobby Brown as art imitates life.
