I'm also rooting for Guillermo Del Toro. :)

I haven't written a musical biopic top ten, but if I did, it would include The Buddy Holly Story, Amadeus, Sid and Nancy, Bird, What's Love Got to Do With It, Control, Ray, and Walk the Line. Honourable mentions would go to The Doors, Hilary and Jackie, La Vie En Rose, Great Balls of Fire, and (if I didn't stick to my ten year rule), Elvis and Rocketman.
