How about Cate Blanchett as Dylan? Gotta see that one!

Also, wasn't Iggy Pop in Coffee & Cigarettes?

I think Whitney Houston makes a credible actor, in that way Willie Nelson does through choice of material that isn't beyond what they are capable of. But I wouldn't describe either of them as being as good at acting as they are at music.

Diana Ross, not so much. I really dislike that dude who played Ray Charles, and the movie sucked. But his portrayal of Charles was pretty good, and he sings really well.

And Sissy Spacek channeled Loretta when she did Coal Miner's Daughter. But as far as I know she considers herself more a baton twirler than a musician.

Reba, OTOH, can NOT act. Seeing her on the tv makes me want to spit.

How about Snoop, eh? The rappers haven't transitioned well into acting I don't think. Too stiff and wooden.

But to me, one of the best film performance by a musician was Bjork in "Dancer in the Dark". She was astoundingly good. It was a really painful film to watch, but really good, IMO.

And Cher in "Moonstruck".

Can't wait to see Monsieur Depp sing in "Sweeney Todd". It is to be our family Christmas outing this year.
