hmm.... di ba may movie na nung 70s na The Color Purple also based on the book? i would think remake na itong kay Spielberg. i've heard good things about it too, tho.
not a musical but i thought "O Brother Where Art Thou" w/ George Clooney et al was hysterically funny! so many subtle but very accurate references to blues/Jim Crow slave culture as well as red neck Americana. unlike "Crossroads" this one represented the person who was known to have really made a pact w/ the devil, Tommy Johnson. music featured blues as well as spirituals, gospel, Appalachian mountain music, etc...
we should do a blues film festival.
