The Grand Rapids Ballet Company is doing Jack the Ripper for the Halloween season. From the article:

Classical ballet has told tales of princesses, mythical personalities and Shakespearean characters, but never about murderers -- which is what intrigued GRBC artistic director Gordon Peirce Schmidt.

"No one's done it," Schmidt said. "To my knowledge, no one's done 'Jack the Ripper.'"

Interesting. I know of operas (Lulu) and scores of songs, movies and TV shows about Jack. There really hasn't been a professional ballet before?
