this be a great mainstream movie with a pop artist in the starring role that have substance . diana ross become billie holiday . i felt like this be billie holiday and this be what she sound like . i even like some of diana version of some billie holiday classic well than the original . ok and i do have some problem with the script ( the script ) . however and it do not really take away from the overall movie . a must see . diana and billie dee williams look great on screen together . this be probably my favorite african american on screen couple of all time . i think the movie have a great mix of dramatic scene mix with musical number and a little comedy ( richard pryor ) to evenly pace this film . lady sing the blue address racism without dwell on the issue or make it big than the movie . the movie should also be commend for make diana ross equally bad and beautiful within the same movie . she look and sound great . billie dee williams and richard pryor also give strong performance . i love richard pryor a piano man . great movie .
