Rigoletto (1993)

The mysterious old mansion on the hill has a new occupant, a disfigured recluse named Ribaldi, and the townspeople are afraid of him. Bonnie is nervous when she goes to work at his mansion, but she soon discovers that he is a musical genius with a beautiful singing voice. As he teaches Bonnie to sing, her kindness melts the ice around his heart to reveal the goodness that has been hidden. A wonderful lesson of tolerance and self-worth.
