There is a story at rollingstone.com about all the rock and country biopics that are being made in the wake of the sucess of "Ray." In the works are movies about Johnny Cash, Brian Jones, and Janis Joplin. The most promising project, though, is about Bob Dylan. Here's a note about the casting:
Filmmaker Todd Haynes, who's directing the Dylan-themed I'm Not There, solved his casting conundrum by splitting Dylan into seven different characters, played by multiple actors -- among them a woman and an African-American boy. "It kind of explodes the idea that anybody could be depicted in a single self," Haynes says of the experimental film, due by early next year.
