First, Sam Mendes and Russell Crowe were attached to direct and star in the film version of Stephen Sondheim's grand, gory musical "Sweeney Todd." Terrific. Add the beatific Emma Thompson as Mrs. Lovett? Wonderful. But now there's a report that Tim Burton and Johnny Depp are the latest creative pair on board. Tragedy. They disgraced the legacy of Willy Wonka, and they'll do the same to "Sweeney." No doubt it will be all CGI, even the meat pies. And we'll have to put up with a Danny Elfman-ized version of Sondheim's glorious score. As Sweeney sings, there's a hole in the world like a great black pit and it's filled with people are who are filled with shit.
